What I'm looking for

I seek backend/cloud engineering roles where I can design scalable infrastructure, improve system reliability, mentor teams, and build developer-focused SDKs with strong CI/CD practices.

I am a Senior Software Engineer with seven years building scalable backend systems, cloud infrastructure, and SDKs for enterprise customers. I have deep experience with Python (Django, FastAPI), Node.js, PostgreSQL, microservices, REST/GraphQL APIs, and AWS services, and a proven record of improving performance and reducing operational costs.

I architect and implement type-safe SDKs and cloud integrations, designed PostgreSQL solutions using JSONB and partitioning, and established CI/CD pipelines achieving high test coverage. I collaborate closely with product teams and open-source contributors to deliver production-ready features that reduce support load and increase reliability.
