What I'm looking for

I’m looking for a team where I can own end-to-end web development—building scalable React/Next apps, strong APIs, and secure auth—while optimizing performance, maintainability, and delivery through Agile and CI/CD.

I’m a Senior Full Stack Engineer with 7+ years of experience building web applications and backends. I specialize in writing clear, concise, maintainable code, and I enjoy troubleshooting and improving performance and reliability across products.

In recent roles, I developed scalable interfaces using React, Next.js, and Angular, built RESTful and GraphQL APIs, and implemented SSR/SSG for better user experience. I’ve also integrated backend services with Node.js/Express, added secure authentication/authorization with JWT and OAuth2, and implemented blockchain features using Web3.js/Ethers.js—often working across small and large teams using Git, CI/CD, and Agile.
