Hi, I'm Ahmad Hanaffi.

My rule for building web applications is simple: ship secure, ship clean. Whether I am leading a frontend team, designing a database-driven app, or testing API endpoints, my main priority is writing code that is easy to maintain and systems that people can rely on.

I do not just write code; I care about how all the pieces fit together. On the frontend side, I build user interfaces using React, Next.js, Vue 3, Nuxt, and Tailwind CSS. When it comes to the backend, I design and deploy REST APIs using NestJS or Laravel, backed by PostgreSQL and containerized with Docker. A huge part of my routine also involves architecture planning and doing thorough code reviews to keep technical debt as low as possible.

Currently open for backend, full-stack roles, and freelance projects. Reach me at [email protected] or explore my work at laznology.web.id.
