App and Software Developer for Businesses in the UAE

iOS & Android apps, web platforms, POS and ordering systems and integrations for companies in Dubai, Abu Dhabi and across the Emirates — delivered by a senior developer just one hour behind UAE time.

Quick answerHakan Sevimoğlu is a freelance full stack and iOS developer in Izmir, Turkey, with 18 years of experience. Turkey (UTC+3) is one hour behind the UAE (UTC+4), and both countries work Monday to Friday, so the working week overlaps almost completely. He builds mobile apps, web platforms, POS and inventory systems, AI integrations and trading software.

Why UAE companies work with a developer in Turkey

The UAE moves fast, and businesses there need developers who can deliver quickly and stay reachable. Turkey is one hour behind UAE time and shares the Monday–Friday working week, so communication is as easy as with a local team — at a fraction of local senior developer costs.

You work directly with the engineer: no sales layer, no hand-offs. The person who scopes your project is the person who builds, launches and maintains it.

What I build for UAE businesses

Customer apps for retail, hospitality and services; ordering, booking and loyalty apps; POS, barcode and inventory systems for retail chains; B2B portals; AI assistants and sales tools; and crypto/trading platforms and exchange API integrations.

Payment gateway, SMS, maps and delivery integrations are API-based; for each project I scope them against the provider's official documentation during the pre-analysis.

Retail and POS experience

I build barcode-based retail software used in multi-branch stores, Kassa — an iPhone POS and inventory app for small businesses — and store analytics with AI-based visitor counting. That experience transfers directly to retail and F&B operations in the Emirates.

Why UAE businesses work with me

  • One accountable developer

    You talk to the person who writes the code. No account managers, no hand-offs between sales and a hidden offshore team.

  • Full stack, end to end

    iOS & Android apps, web platforms, backends, APIs, ERP modules and hardware/IoT — designed, built, deployed and maintained by the same engineer.

  • Staged delivery

    Work is split into milestones you can test. You approve each stage before the next one starts, so budget and scope stay under control.

  • Source code ownership

    The code, repositories and accounts are yours. Documentation and handover are part of the job, not an extra.

  • Async-friendly communication

    Written updates in English, a shared task list, and short video calls when a decision needs to be made together.

  • Long-term maintenance

    18 years in the field means many systems I built are still running years later. Post-launch support is planned from day one.

Frequently asked questions

What is the time difference between the UAE and Turkey?

The UAE is UTC+4 and Turkey is UTC+3, neither with daylight saving, so Turkey is always one hour behind UAE time.

Do our working weeks overlap?

Yes. The UAE federal working week runs Monday to Friday, as in Turkey, so the working week overlaps almost entirely.

Can you build iOS and Android apps for the UAE market?

Yes. Native iOS apps in Swift/SwiftUI and Android apps, with a web admin panel and API backend, including App Store and Google Play submission.

Can you integrate local payment gateways?

Payment integrations are API-based; I scope the specific gateway against its official documentation in the pre-analysis and include it in the written proposal.

Do you work in English?

Yes. All communication, documentation and the product interface can be in English.
