What I'm looking for

I seek a collaborative team role building secure, scalable web applications where I can apply React/Node skills, contribute to architecture, and grow technically.

I am a motivated Fullstack React & Node.js developer with practical experience building healthcare, government, and B2B e‑commerce applications using React, TypeScript and Next.js.

I deliver secure, scalable solutions—implementing REST APIs, optimizing performance with NGINX, and maintaining React libraries—while collaborating closely with cross‑functional teams to meet project milestones.

My background includes end‑to‑end testing with Cypress and CI/CD, server work with Java Spring Boot, and a strong attention to detail that drives reliable, maintainable products.
