What I'm looking for

I’m looking for a team where I can build and improve high-performance web platforms—pairing React front ends with scalable back-end services, GraphQL/REST integrations, and reliable CI/CD and cloud deployments to ship impactful features fast.

I’m a Software Engineer experienced in developing end-to-end web applications with React, Node.js, Python, and modern frameworks. I focus on building interactive front-end interfaces, optimizing back-end performance, and delivering seamless user experiences.

In my recent role, I designed and implemented a high-performance web platform that improved user engagement by 35%, built a microservices-based architecture for faster feature deployment, and integrated GraphQL APIs to reduce frontend data-fetching time for over 50,000 daily users. I also migrate legacy systems, optimize PostgreSQL and MongoDB queries (40% faster retrieval), and automate releases with CI/CD pipelines using GitHub Actions and Docker to achieve zero-downtime deployments.
