What I'm looking for

I am seeking frontend roles focused on React/Next.js where I can modernize systems, improve UX and performance, and work within collaborative Agile teams.

I am a frontend developer with four years of experience building scalable, responsive web applications using React.js, Next.js, and micro-frontend architecture. I specialize in modernizing legacy systems, creating reusable design systems, optimizing performance, and working closely with cross-functional teams to deliver enterprise-grade solutions.

I have driven measurable improvements—raising Jest unit-test coverage from 60% to 85%, resolving SonarQube issues to reduce vulnerabilities, and implementing CI/CD practices that cut deployment errors. I bring strong problem-solving, collaboration, and Agile experience to support ongoing product excellence.
