About Me
Ilyas Sülen
AI Engineer & Python Backend Developer
I’m interested not only in what an AI model can generate, but in how it becomes a reliable application. That is why I combine clean backend logic, structured data flows and grounded retrieval to build systems that are understandable, maintainable and useful.
Turning complex problems into clear services, data flows and responsibilities.
Building on real context, retrieval and verifiable structured outputs.
Creating code that stays understandable, maintainable and extensible.
Let’s connect
I’m especially interested in Python backend development, FastAPI systems, AI-powered applications, RAG and retrieval systems, and products that turn complex ideas into reliable software.
