Ahmad Hanaffi — Backend & Fullstack Developer, Yogyakarta, Indonesia
Building backend architecture and clean frontend interfaces that hold up in production.
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 hello@laznology.dev or explore my work at laznology.dev.

Core engineering principles & decision standards.
SECURITY IS NOT A FEATURE
It's the foundation. Payment data, user credentials, and privacy cannot wait until 'phase two'.
CODE THAT LASTS > CODE THAT WORKS
Code that 'just works' isn't enough. It must be readable, maintainable, and built to scale.
CLARITY OVER CLEVERNESS
A crystal-clear function is always better than a clever one-liner that no one understands three months later.
SHIP FAST, NEVER SLOPPY
Deadlines can be negotiated. Quality standards cannot.
ARCHITECTURE FIRST
UI can be iterated. A broken database schema is a migration nightmare.
