I am a Full Stack Engineer with over 8 years of experience building scalable web applications and high-performance user interfaces, specializing in the React/Next.js ecosystem. I prioritize code quality, security standards (OWASP), and modern DevOps practices, and have driven measurable results such as a 66% reduction in page load time and improved organic visibility through SSR-based SEO strategies.

I have architected and delivered products across domains including airline ticketing portals, e-commerce UI modernizations, MVPs for health tech, and real-time ordering platforms, working with technologies like Next.js, GraphQL, Node.js, MongoDB, TypeScript, and Docker. I am open to international relocation and require sponsorship/visa to work.
