Ahmad Haizul Amany

Full Stack Developer

I'm Heinz, a full-stack developer and informatics student passionate about building modern, scalable web apps. I work with React, Next.js, TypeScript, and backend tools like Prisma and PostgreSQL. I enjoy crafting clean code, exploring new tech, and delivering user-friendly digital experiences.

How I Work

I like building from the middle of design and engineering: enough structure to keep a product maintainable, enough visual care to make it feel memorable. My best work usually starts with a clear problem, a small set of constraints, and a willingness to polish the details people actually touch.

The stack I reach for most often is Next.js, TypeScript, Tailwind CSS, Prisma, PostgreSQL, and small interface systems that make repeated work easier. I care about fast pages, useful content models, and interfaces that still feel calm after the hundredth visit.

What I Value

Clear communication before clever implementation
Responsive interfaces that feel intentional on every screen
Server-first architecture with client components only where interaction needs them
Content workflows that let projects grow without constant code edits
