Backend depth
.NET, C#, relational and document databases, messaging, caching, search, and the patterns that keep them maintainable.
Software developer · Istanbul
I turn complicated systems into software people can rely on.
I’m Barış Çelebi — a software developer with strong backend foundations and a product mindset. I care about what happens behind the interface, what reaches the person using it, and every decision between the two.
A little about me
Law taught me how to reason. Software gave me somewhere to build.
I began my career as a lawyer after graduating from Istanbul Commerce University. In 2022, I made the decision I had been circling for years and moved into technology.
Since then, I’ve built strong backend experience while expanding into frontend, infrastructure, deployment, and product design through my own projects and AI-assisted workflows. The career changed; the habit of examining complex problems from every angle stayed.

How I work
Clear thinking. Durable systems. Useful outcomes.
I’m at my best where business rules, data, integrations, and operational realities meet. I like systems that are easy to explain, observable in production, and built to change without drama.
Whole-product curiosity
I cross into React, Next.js, mobile, and design when understanding the complete experience makes the system better.
Production ownership
Linux, Docker, CI/CD, cloud services, monitoring, and the practical work of keeping software alive after launch.
