We do not just design systems for clients — we run our own products in production.

Wallet and Legal were written, released and are maintained by this same team.

  • The same architecture
  • The same pre-release checks
  • The same security discipline

We will build what you have in mind: an app for iOS and Android, macOS, Windows and the web, a customer portal, an AI assistant, a Telegram bot, an integration with your systems or automation of manual work. We start with the problem, not the technology.

Under wraps until launch

The main thing is still in the making

The main JEEKSSHIRE 24 app

Right now we are building the JEEKSSHIRE 24 flagship — the most ambitious project in the company. We will show it in full on release day: how it works, what it is built from and what it solves.

For now, two showcases of the ecosystem are open — Wallet and Legal — and they show how we build products.

Materials, interfaces and technical details will appear on this page on launch day.

More on it soon The main JEEKSSHIRE 24 app is getting ready for launch. We will reveal it here together with the release — not a word before then.

Capabilities

What we build

iOS and Android, macOS and Windows, the web. One codebase where it pays off, and native builds where speed matters. Auto-updates, code signing and notarization, installers, app store publishing. Read more: Mobile apps.

  • iOS
  • Android
  • macOS
  • Windows
  • Web
  • Telegram

An agent that reads your documents and data, answers your staff and carries out work steps instead of just chatting. Read more: AI agents and chatbots.

Bots with buttons, conversation state and Mini Apps inside Telegram — for requests, notifications, payments and internal processes. Read more: Telegram bots.

Where staff move data by hand, we set up data exchange between systems, queues, checks and reporting. Read more: Process automation.

A customer portal, an admin panel, a dashboard for monitoring a fleet and money flows — with access rights and an action log. Read more: Web applications.

Connecting checkouts, subscriptions, refunds and reconciliations. Money is calculated on the server, and the customer sees the result.

Bringing your CRM, warehouse, email and messengers into one workflow without copying data between windows.

Four languages and right-to-left layout are built into the architecture from the start, not bolted on before a market launch.

Company websites, product landing pages and web services in several languages: responsive, fast, with request forms and a link to the app. Read more: Company and product websites.

Extensions for Chrome, Edge, Firefox and Safari: a button on the right page, data capture into your CRM, hints and an AI agent connection. Read more: Browser extension development.

Indexing, markup and sitemap, goals and conversions, Google Ads, Yandex Direct and VK Ads accounts with a test budget. Read more: SEO and ads at launch.

Process

How we work

  1. Step 1

    Understanding the problem

    We look at what is holding the business back today, where money and time are lost and what result counts as success. Sometimes this step shows that you need a bot, not an app.

  2. Step 2

    Solution and estimate

    We propose the simplest solution that delivers the result and break it into parts that can be shown and checked one by one.

  3. Step 3

    Building in parts

    You see working pieces as we go, not a single handover at the end, and you can reshuffle priorities between parts.

  4. Step 4

    Checks and release

    Build, lint and tests run before deployment. If the gate is red, there is no release, however urgent it is.

  5. Step 5

    Monitoring and growth

    We set up failure alerts and backups so that you hear about a problem from us, not from your customers.

Release gate: try it yourself

Turn off any check and the deployment stops. That is how every release of ours works.

✓ build

✓ lint

✓ tests

→ release allowed

Timeline and deliverables

How long development takes and what you get

The timeline depends on scope, so we give an exact figure after reviewing the task. Below are guidelines from our experience.

A Telegram bot or a small automation

Usually one to several weeks: a bot with a clear scenario, data exchange between two systems, a report that used to be compiled by hand.

An AI agent on your data

A first working version usually takes a few weeks: we connect the sources, set access boundaries and test the answers on your real examples, then expand.

A multi-platform app

A standalone product for iOS, Android, macOS, Windows or the web takes several months or more. We ship in stages: a first version with the main scenario comes out earlier, the rest follows in later releases.

What you get at the end

A working product in production, the source code and the rights to it, a description of how the product is built and how to release it, configured failure alerts and backups. After that — maintenance and further development as agreed.

5 platforms in one project

iOS, Android, macOS, Windows and the web

184 interface languages

from Russian, English and Chinese to Arabic and Hebrew — with right-to-left layout

10+ in-house products in production

built, shipped and maintained by this same team

1 team from brief to launch and growth

analysis, build, release and monitoring — nothing outsourced

Principles

Why us

01

We use what we build

Wallet and Legal are not slide-deck portfolio items but working products with users, updates and accountability for outages. Clients get the same engineering culture.

02

We solve causes, not symptoms

Our rule: solve a problem at its source instead of covering it up. That keeps the code free of patches, and maintenance costs go down over time instead of up.

03

Less code, less risk

We look for an existing path in the system first and only then add a new one. A simple solution is cheaper to build, faster to verify and safer to run in production.

04

Release only when everything is green

Build, checks and tests run before deployment, not after. If the gate is red, there is no release, however urgent it is.

05

Security and privacy by default

Data does not travel where it has no business being. In Legal, recognition runs in the browser; in Wallet, payment routes are isolated — your product gets the same approach.

06

We speak plainly

We explain decisions in terms of your problem, not our tech stack. You understand what you are paying for and why this path was chosen — and you can challenge it on the merits.

Focus areas

Custom development: AI agents, Telegram bots, macOS and Windows apps

JEEKSSHIRE 24 is a software development team that designs, builds and maintains products end to end: from architecture and interface to release, monitoring and updates. We work for clients and on our own products, so our decisions are tested on real users, not in a slide deck. We are strongest where we already have a working product of our own.

AI agent development for business

The agent works with your documents, emails and knowledge base: it finds what matters by meaning, prepares drafts, answers employees and customers and triggers process steps. You set the access boundaries, and every action the agent takes is visible in the log. Our track record is Legal: its AI lawyer reviews a contract, flags risky terms and opens the relevant section of the document.

Chatbot and Telegram Mini App development

Bots for requests, notifications, payments and internal processes: buttons, conversation state, broadcasts and an admin panel. When buttons are not enough, we build a Telegram Mini App — a full interface inside the messenger with a catalog, forms and a personal account. We connect the bot to your CRM, spreadsheets and website so nobody has to copy data by hand.

macOS and Windows apps

Desktop apps with an installer, code signing and notarization, auto-updates and access to files on the computer. That is how our own products work: Wallet and Legal have Mac and Windows versions alongside the web version.

Multilingual products: Arabic and RTL

Russian, English, Chinese and Arabic are built into the architecture from day one: copy is kept separate from code, and for Arabic the interface is mirrored right to left (RTL). Wallet runs in four languages, including Arabic, so entering Middle Eastern and Chinese markets does not mean rewriting the interface.

Mobile and web app development, client portals

iOS and Android apps, customer portals, admin panels and web services. One codebase where it pays off, and native builds where speed matters. Publishing to the app stores is part of the job.

Business process automation and integrations

We take repetitive work off your staff: moving data between the CRM, warehouse, email and messengers, manual reconciliations, status updates and reporting. The process gets a queue, retries and a log, so you see it as a whole rather than through people's accounts.

MVP development and phased launch

The first version with the core scenario ships early, the rest follows in later releases. Sometimes the discovery stage shows that a bot is enough instead of an app — then we start with the bot and test the idea faster.

Improving and maintaining existing code

We start by reading the code and working out what is really going on, then propose a plan: what to improve first, what to rewrite and what is better left as it is. After launch we set up monitoring, failure alerts and backups.

Websites and product landing pages

A company website and product pages in several languages, including right-to-left Arabic: fast pages, responsive on phone and desktop, SEO markup and a sitemap, analytics and enquiry goals and a link to the app — downloads for macOS and Windows, sign-in to the web version, an enquiry form. That is how the JEEKSSHIRE 24 website and the Wallet, Legal and Content Factory pages are built.

Browser extensions

Extensions for Chrome, Edge, Firefox and Safari: a button right on the page where an employee works, data capture into your CRM and spreadsheets, hints from your systems and a side panel with an AI agent. Access only to the sites that need it, keys stay on the server, and we handle publishing in the extension stores.

SEO and ad account setup

We prepare the product for search and ads: separate language URLs, hreflang, Schema.org, a sitemap and IndexNow, goals and conversions that respect cookie consent. We set up Google Ads, Yandex Direct and VK Ads: keywords from real query statistics, negative keywords, a test budget and growth for the campaigns that pass the test. This is how we launch ads for our own products.

Security from the first commit

A strict source policy, separated environments, validation of every incoming field, secrets kept outside the code and the repository. This is not a separate stage before handover but a requirement for every change — that is how our own products are built.

Questions

Frequently asked questions

Do you take on projects of any size?

Yes. Sometimes a task is solved by a bot or a small automation in a week, sometimes by a standalone product over several months. At the first review we will tell you honestly what size you actually need, even if it is smaller than you expected.

Where do I start if I have no technical specification?

A ready specification is not required. Describe the task in your own words in the form below: what gets in the way today and what result you need. At the discovery stage we will work out together what to build and split the work into parts. Read more: Writing a software brief.

How long does development take?

A Telegram bot or a small automation usually takes one to several weeks, a first version of an AI agent a few weeks, and a standalone app several months or more. We give the exact timeline after reviewing the task and ship the product in stages so you get value sooner. Read more: App development timeline.

How is the work scheduled?

We split the task into parts that can be shown and checked. You see working pieces along the way rather than one handover at the end, and you can reprioritise between parts.

What exactly can AI agents do?

Review documents and correspondence, answer from the company knowledge base, prepare drafts, search by meaning and trigger process steps. The agent works with your data within the boundaries you set, and its actions are visible in the log. Read more: AI agent for business.

Do you build Telegram bots and Mini Apps?

Yes. We build bots for requests, notifications, payments and internal processes, and when a full interface is needed, a Telegram Mini App with a catalog, forms and a personal account. We connect the bot to your CRM, spreadsheets and website. Read more: Telegram bot for business.

Can you build an app for macOS and Windows?

Yes. We build desktop apps with an installer, code signing, notarization and auto-updates. Our products Wallet and Legal have Mac and Windows versions alongside the web version. Read more: Desktop apps.

Can you build for Arabic and right-to-left layout?

Yes. Languages are built into the architecture from day one, and for Arabic and Hebrew the interface is mirrored right to left (RTL). Wallet runs in Russian, English, Chinese and Arabic; the Legal interface is available in 184 languages.

Can you improve something written by another team?

Yes. We start by reading the code and working out what is really going on, then propose a plan: what to improve first, what to rewrite and what is better left as it is. Read more: Ongoing development.

Who owns the code?

The client. Together with the product we hand over the source code, the rights to it and a description of how the product works and how to release it. The terms are set in the contract before work begins. Read more: Project acceptance.

What happens after launch?

We set up monitoring, alerts and backups and agree on a maintenance arrangement. The product stays alive: updates and further development are part of the work, not a separate story.

How is custom development different from an off-the-shelf solution?

An off-the-shelf solution works when your process matches the way it is designed. Custom development is built around your process and your systems, and the source code and the rights to it stay with you. A middle path often makes sense: a ready-made system plus integrations and automation around it. Read more: Custom vs off-the-shelf.

Can we start with an MVP?

Yes, and that is usually the right way to start. The first version with the core scenario ships early and the rest follows in later releases, so you get value before the whole product is finished. Read more: MVP development.

Do you build websites and landing pages?

Yes. We build company websites and product landing pages: multilingual, responsive on phone and desktop, with SEO markup and analytics. The JEEKSSHIRE 24 website and the Wallet, Legal and Content Factory pages were made by our team. Read more: Company and product websites.

Do you build browser extensions?

Yes. We build extensions for Chrome, Edge, Firefox and Safari: a button on the right page, data capture into your CRM, hints from your systems and an AI agent connection. An extension with one workflow usually takes one to two weeks plus store review. Read more: Browser extension development.

Do you handle SEO and ad account setup?

Yes. We prepare the site for search — language URLs, markup, the sitemap, indexing — and set up Google Ads, Yandex Direct and VK Ads: campaigns, goals and conversions, negative keywords and a test budget. We launch ads for our own products the same way. Read more: SEO and ads at launch.

What is the shortest development time?

A Telegram bot, a browser extension or a landing page with one workflow — from one week. Complex products ship in parts: the first version with the core workflow comes out sooner, the rest in later releases. Read more: App development timeline.

Can a landing page be connected to the app?

Yes. The product page gets downloads for macOS and Windows, sign-in to the web version and an enquiry form, and visitor steps show up in analytics — so you can see how many people reached a download or an enquiry.

How is a website found in search in different languages?

Each language version has its own address, reciprocal hreflang links, Schema.org markup and a place in the sitemap. Search engines then show visitors the version in their language rather than one shared page.

What are the stages of software development?

Task review, solution and estimate, building in parts, testing and release, then monitoring and growth. Each stage ends with something you can see and check, and acceptance follows a list agreed in advance.

How much does app development cost?

The price depends on scope and timeline, so we do not publish a price list — it would be misleading. Describe your task in the form below and we will come back with an estimate and a step-by-step plan. Read more: Software development cost.
