What I'm looking for

I’m looking for a Full-Stack Developer role where I can build secure, scalable web apps and APIs using React/Node, strong testing, and modern deployment—shipping production-ready features and improving continuously through practical engineering.

I’m a Full-Stack Developer focused on building secure, scalable web apps and APIs, from authentication and APIs to deployment and quality. I enjoy shipping production-ready code and improving reliability through testing and careful integration of third-party services.

In open source, I’ve contributed merged PRs with full test coverage in freeCodeCamp, and I’ve worked on critical TypeScript typing fixes in Mongoose that required comprehensive assertion coverage. I also improved express-mongo-sanitize by resolving Express v5 query sanitization compatibility issues and adding stability tests.

On my own projects, I build end-to-end systems like a secure MERN e-commerce platform with JWT authentication, HttpOnly cookies, CSRF protection, PayPal integration, and Dockerized deployments. I’m currently pursuing an M.S. in Software Engineering while continuing to develop real-world applications and stronger engineering practices.
