Web application development company for custom portals and services

JEEKSSHIRE 24 is a web application development company that builds browser-based tools for real business work: customer portals, admin panels, internal systems, custom CRM and SaaS platforms. We run the project end to end, from understanding the task to release and ongoing support. The web versions of our own products, Wallet and Legal, are built and maintained by the same team, so clients get the same engineering discipline.

Custom web application development services we offer

People work in a web app rather than just read it: they sign in, place orders, upload documents and check reports. We build it around your process, not around a template.

• Customer or partner portals: orders, payments, documents, history and notifications.
• Admin panels for your team: catalog, requests, users and permissions, with an action log.
• Custom CRM development when off-the-shelf systems do not match how you sell or serve clients.
• SaaS platforms with plans, roles and a separate workspace for each customer.
• Internal tools and web portals: requests, approvals, reports and a knowledge base.
• A web version of an existing product next to its mobile and desktop apps, including PWA.
• Payment flows: subscriptions, refunds, reconciliation, with amounts calculated on the server.

The same team also builds iOS and Android apps and desktop apps for macOS and Windows.

Who a custom web app is for and what problems it solves

Custom development pays off when a boxed product needs too many workarounds. Typical cases:

• Clients keep asking about order status that a portal could show them.
• Requests live in messengers and spreadsheets instead of one queue with statuses and owners.
• Your CRM does not match your process, so staff keep a parallel record in spreadsheets.
• You are launching your own product and testing it with first users, so we start with an MVP.
• You are entering new markets and need the interface in several languages, including Arabic.

Not sure whether to build or buy? See custom vs off-the-shelf software. Sometimes process automation or a bot is simpler, and we say so.

How we build a web application, step by step

Work is split into parts you can see and check along the way.

1. Understanding the task. What gets in the way and what success looks like. A formal specification is optional; see our guide to the software requirements document.
2. Solution and estimate. The simplest solution that delivers the result, split into parts with an indicative timeline.
3. Design. Data, access rights, user flows and key screens, including languages and right-to-left layout.
4. Building in parts. The main scenario first, then the rest. Priorities can change between parts.
5. Checks and release. Build, lint and tests pass before deployment. A red check means no release.
6. Monitoring and growth. Failure alerts, backups, fixes and new features as agreed.

What you receive at the end

• A working web service in production, not a mockup or a demo stand.
• The source code and the rights to it, with terms fixed in the contract before work starts.
• A description of how the product is built and released, from the data structure to the release procedure.
• Configured failure alerts and backups.
• Ongoing maintenance and development as agreed; see software maintenance and support.

How to check finished work before you sign off is covered in our software project handover checklist.

Our own example: Wallet and Legal on the web, and the JEEKSSHIRE 24 website

We run web products in production ourselves.

Wallet in the browser

A wallet for paying for foreign digital services: catalog, balance, order history and refunds, in the browser and on Mac and Windows. It has an order queue with statuses and automatic refunds, a strict content security policy and isolated payment routes. The interface works in four languages, including Arabic with right-to-left layout. See the Wallet page.

Legal in the browser

An AI document editor: draft a contract from a description or review your own, work with PDF and DOCX, and extract text from images. Text recognition runs in the browser, so the document does not have to leave the computer. The interface is available in 184 languages, including right-to-left ones. More on the Legal page.

The JEEKSSHIRE 24 website

Built by the same team: four language versions generated from one source, each with its own URL, hreflang and Schema.org markup, adapted for phone and desktop.

Web app, website or mobile app: which to choose

The right platform depends on who uses the service and how often. A short comparison:

If your product also needs a showcase, see the guide on product website development.

Security, access roles and integrations

Security is a requirement for every change: validating every input field, separating permissions by role, logging admin actions, keeping secrets out of the code and enforcing a strict content security policy in the browser.

A web service rarely lives alone. We connect it to your CRM, warehouse, accounting, email and messengers so nobody copies data by hand. Notifications and requests can also go to a Telegram bot, and document review or answers from a knowledge base can be handed to an AI agent.

Multiple languages are part of the architecture from day one: texts are separated from code, and for Arabic the interface is mirrored right to left.

What affects web app development cost and timeline

We give an exact estimate after reviewing the task. Scope and timeline depend on:

• the number of roles and screens: client portal, manager panel, admin;
• integrations with external systems and the quality of their APIs;
• payments, subscriptions, refunds and reconciliation;
• security and logging requirements;
• the number of languages and right-to-left layout;
• migrating data from an old system.

As a guide, a small automation takes from one to several weeks and a standalone product from several months, with the first version shipping earlier.
