I’m a Full Stack Developer with 4.5+ years of experience building scalable web applications, with strong expertise in React.js and Next.js and growing depth in backend systems using Node.js and modern databases. Over the years, I’ve worked on SaaS products across domains like HR tech and maritime analytics, contributing to both frontend architecture and backend systems. My work includes building complex dashboards, designing API integrations, and handling real-time data-driven features. Recently, I’ve been focusing more on full stack development — working on database migrations (MongoDB → PostgreSQL), designing relational schemas using Prisma, and delivering end-to-end features from backend APIs to frontend interfaces. I enjoy solving problems that involve performance optimization, clean architecture, and scalable system design. Whether it's improving application responsiveness, structuring data efficiently, or building intuitive user experiences — I like taking ownership of features end-to-end. Tech I work with: • Frontend: React.js, Next.js, TypeScript, Tailwind, Redux • Backend: Node.js, Express, Next.js APIs • Databases: PostgreSQL, MongoDB, Prisma, Redis I’m currently open to opportunities where I can contribute as a Full Stack Developer and work on impactful, scalable products.
