What I'm looking for

I’m looking for a Python-focused backend role where I can build reliable RESTful services, modern cloud-native systems, and data/ML features (including AI integrations) using clean architecture and hands-on engineering.

I’m a software engineer with 13 years of enterprise software engineering experience, transitioning from a strong Java and Spring Framework background into Python-based backend and data-oriented systems. I build RESTful APIs with clean separation of concerns and layered architecture to keep services maintainable and scalable.

As Founder / Lead Backend Developer, I’m designing end-to-end backend systems with Python and FastAPI, integrating Supabase (PostgreSQL), Redis-based rate limiting, Dockerized local environments, and OpenAI-compatible LLM features. Earlier roles building Java microservices in Azure & Docker improved critical component performance by up to 90%, while comprehensive unit testing raised development efficiency by 80%.
