What I'm looking for

Frontend Developer with 5+ years of experience building fast, accessible, production-grade interfaces with React.js and

Next.js. Deep expertise across component architecture, state management, design systems, performance optimisation, and API

integration — backed by working backend fluency (Python, Django, PostgreSQL) that sharpens cross-team collaboration.

I’m a versatile Full Stack Developer with 5+ years delivering end-to-end web applications, from pixel-perfect responsive UIs in React.js and Next.js to scalable, secure backend APIs and microservices with Python, Flask, and Django. I comfortably own the full product stack—UI implementation, REST API architecture, database design & optimization, authentication/security, and cloud deployment on AWS.

In my recent role as a Senior Full Stack Developer, I migrated a legacy PHP monolith to a Python microservices architecture on AWS ECS, built event-driven workflows with Apache Kafka, and improved performance through PostgreSQL indexing and Redis caching. I also build CI/CD automation and mentor junior engineers, aiming for faster releases, measurable uptime, and products that work reliably for real users.
