What I'm looking for

I’m looking for a team where I can build scalable Python/React systems and production-grade LLM features, own end-to-end delivery, and improve observability and CI/CD. I want to lead through mentorship while shipping measurable business impact.

I’m a Senior Full Stack Engineer with 7+ years of experience building scalable full-stack and backend systems. I specialize in Python (FastAPI), React, and cloud infrastructure (AWS), and I focus on designing high-performance APIs and reliable production deployments.

I’ve delivered AI-powered features in real environments by integrating LLM-driven workflows and agent-like patterns into backend systems. I also emphasize operational excellence—improving observability, documentation, and end-to-end delivery from requirements gathering to deployment and iteration.

I’ve led teams through full delivery cycles as a Team Lead, mentoring junior engineers and driving performance and scalability improvements. Whether it’s CI/CD pipelines, Docker-based releases, or database and system tuning, I aim to reduce operational overhead and ship solutions that create direct business impact.
