What I'm looking for

I’m looking for an opportunity to apply my backend development experience to larger, more challenging projects—building reliable products with talented teams, learning modern technologies, and improving how I design scalable systems.

I’m a Senior Python Backend Developer with 7+ years of experience designing and delivering scalable, reliable backend systems in fast-paced environments. I build high-performance RESTful APIs with Python (FastAPI), implement secure authentication, and structure microservices for dependable production outcomes.

Most recently, I’ve led backend architecture discussions and mentored junior developers while integrating cloud infrastructure and containerized CI/CD deployment pipelines with Docker and Kubernetes. Earlier, I developed backend systems and automation using Django and Flask, optimizing PostgreSQL and improving stability, scalability, and release performance.
