What I'm looking for

I’m looking to build reliable, secure, scalable systems end-to-end—owning architecture and performance, improving CI/CD, and delivering containerized AWS services that modernize products with strong engineering discipline.

I’m a Senior Software Engineer focused on scalable full-stack systems and cloud-native architectures, building production-grade microservices and secure REST APIs. I bring strong ownership across architecture, performance optimization, CI/CD automation, and containerized deployments with Docker, with an emphasis on reliability and security.

In my recent work, I architected e-commerce services with NodeJS, Express, and PostgreSQL to support high-volume order processing, while improving checkout stability using React, NextJS, and TypeScript. I accelerated product discoverability by integrating Elasticsearch (including dynamic indexing and inventory updates) and improved search responsiveness by optimizing query reliability and high-traffic performance.

I’ve also built secure healthcare dashboards and backend systems, including real-time clinical visibility with React/NextJS/TypeScript and role-based access control via NodeJS/Express APIs. Earlier, I strengthened cybersecurity services by automating security validation in CI/CD with DevSecOps checks and improving AWS configuration compliance—helping reduce vulnerabilities and harden release workflows.
