Web apps built properly,
from the backend up.
I build custom applications where the backend actually matters — real-time data systems, payment integrations, and the infrastructure to keep them running. Not templates, not page builders. Systems you own, in code you can hand to anyone.
What I'm usually hired for.
Work that needs a developer rather than a plugin — where the requirements don't fit an off-the-shelf product.
Real-time systems
Live dashboards, event streams and push notifications over WebSockets. Continuous ingestion pipelines that stay up, recover from upstream failure and don't hammer their sources.
Payments & integrations
Payment gateways, webhooks and third-party APIs wired into your own systems — with the retry logic, idempotency and reconciliation that separate a demo from something you can bill through.
Custom platforms & portals
Client portals, admin systems and internal tools: authentication, roles and permissions, audit trails and reporting. Built around your actual process rather than a template's assumptions.
Data platforms
Aggregation, normalisation and scheduled processing at volume. Turning messy external feeds and APIs into something clean, cached and fast enough to serve directly.
Legacy PHP rescue
Inherited a codebase nobody understands? I work through undocumented systems, stabilise them, close the security holes and modernise incrementally — without a rewrite you can't afford.
Infrastructure & deployment
Linux servers, managed hosting, web stacks, TLS, mail, DNS, CDN and backups. I can host and run the apps I build — not a standalone service, but there if you want performance and uptime handled rather than left to someone else after launch.
Plugged into the ecosystem.

Fixed scope. Visible progress. Code you own.
Scope & proposal
We talk through the problem before anything is quoted. You get a written scope with deliverables, assumptions and a fixed price — not an hourly estimate that drifts.
Architecture
Data model, integrations and failure modes agreed up front. This is where the expensive mistakes get caught, while they're still just a diagram.
Build in milestones
Work lands on a staging environment you can use throughout. Milestone payments tied to working software, so you're never paying for progress you can't see.
Launch & handover
Deployment, monitoring and a documented handover. Full source and infrastructure access transfers to you — no lock-in, no proprietary layer you have to keep paying for.
Fifteen years of shipping.
I've been building and running web systems since 2011 — from early Python automation and data work through to real-time platforms and payment integrations. Along the way I built a mobile airtime top-up service that accepted Bitcoin, when that meant writing the settlement logic yourself, and ran a UK hosting company with hardware colocated in a London data centre.
That background shapes how I build. I've been the person on call when a server fails at 3am, so I write code that fails predictably and logs enough to diagnose. I've integrated payment rails and third-party APIs that break in production, so I plan for retries, partial failures and reconciliation from the start.
I work solo and take on a small number of projects at a time. You deal with the person writing the code — no account manager, no handoff to a junior team after the pitch.
I also work with modern, AI-assisted development — tools like Claude Code and Antigravity sit alongside my own testing and review, so I ship faster without cutting corners on quality or security. The AI accelerates the typing; the judgement about what to build, and what can safely go wrong, stays with me.

Built for working with international clients.
I work in English and I’m based in Istanbul on UTC+3 — two hours ahead of London, one ahead of most of Europe. That means a normal shared working day: same-day answers, calls at sensible hours, and no waiting overnight for a reply to a blocking question.
Every project runs on a written contract with a fixed scope and milestone payments. Where personal data is involved, I work to a written data processing agreement and the transfer safeguards UK and EU GDPR require — prepared up front, not negotiated afterwards.
Tell me about the project.
