I’m a full-stack developer with 10+ years of experience building production-grade web applications and distributed systems, focusing on scalable backend architecture and reliable API-driven platforms. I work across Python/Django with GraphQL, REST APIs, relational databases, caching, and async/background processing, and I’m comfortable designing data models and optimizing query performance for real-world workloads. I also contribute end-to-end by building front-end experiences with React/Next.js and mobile solutions, integrating third-party services, and setting up cloud infrastructure on AWS with Docker and CI/CD practices. From leading technical design discussions and mentoring engineers to handling system planning and performance improvements, I enjoy turning business requirements into maintainable, secure, and high-availability software.
