Available for freelance & contract work
Hi!I'm Arda.
Freelance Software Engineer based in Berlin. I design and build fast, reliable web products for clients, from the first pixel to production infrastructure.
- TypeScript
- React
- Next.js
- Node.js
- PostgreSQL
- Docker
What I do
End-to-end web engineering for teams that want to ship.
I work with founders, agencies and product teams as an embedded engineer or on scoped projects, taking ownership from concept to production.
Full-stack & real-time systems
APIs, auth, data models and WebSocket-driven features. I take a product from an idea to a working system and keep the architecture simple enough to hand over.
- Node.js
- Express
- PostgreSQL
- Prisma
- Socket.IO
- Python
Infrastructure & delivery
Containerized services, CI/CD pipelines and hosting that fits the project: Vercel for the frontends, Docker on a VPS for what needs to stay under your control.
- Docker
- GitHub Actions
- Nginx
- Vercel
- Linux
Selected work
Things I've shipped.
A few projects that show how I work: real users, real infrastructure, and code I'm happy to hand over.

How I work
Senior hands you can hand a problem to.
Whether it's a greenfield product or a codebase that needs to move faster, I plug in quickly and leave things better documented than I found them.
- Ownership, end to end
- I'm comfortable across the whole stack, so there's no hand-off gap between design, frontend, API and deployment. One person, one thread of responsibility.
- Built to last, not just to launch
- Typed code, tests where they matter, and a deployment you can run without me. You get a codebase your next developer can pick up without a handover call.
- Clear, async-friendly communication
- Short written updates, demos you can click, decisions documented. Remote-first from Berlin, English or German.
