What I'm looking for

I seek backend roles focused on building secure, scalable APIs and cloud-deployed services, with strong testing, CI/CD, and collaborative teams.

I am a results-driven backend engineer with a foundation in Chemical Engineering and focused training in backend development. I build secure, scalable APIs and systems using Node.js, Express, and modern databases, with attention to authentication, authorization, and API security.

At Helium Health I optimized Node.js/Express APIs and database queries to process 1,000+ daily patient records, reducing data processing time by 25% and improving platform adoption through user feedback endpoints by 40%.

I deploy and maintain services on AWS, use Docker and GitHub Actions for CI/CD, and emphasize testing and documentation (Jest, Supertest, Postman, Swagger) to deliver reliable, production-ready backends.
