Hello!

I am Febriyan Ahza — a programmer who build systems that work, and I care deeply about how they work. Most of my time goes into distributed systems, networking, and the kind of foundational problems where you need to think carefully about what happens when things inevitably break or scale. I also lean toward the mathematical abstractions underneath — category theory, machine learning theory — not because they're fancy, but because they often reveal the obviously correct way to structure a solution.

My path here wasn't straight. I studied literatures in high school. Strange choice for someone who writes code now, but it stuck with me: the discipline of precise expression, the structure of grammar, the way meaning composes from smaller parts. Turns out that's exactly how I think about programs — as systems of meaning that need to be clear, consistent, and built from simple pieces that fit together naturally.

I switched to STEM later and arrived at university with zero programming experience. I just started building things, one step at a time, trying to close the gap between how things are and how they should be. That gap still bothers me. It's what drives most of my work, removing accidental complexity, making APIs cleaner, making systems more robust to time. As Feynman phrase it, "The pleasure of finding things out."

I spent time on CryptoHack, solving cryptography puzzles. I didn't go deep into security, but it shaped how I think about systems — especially the mathematical invariants that keep them correct under adversarial conditions. Good puzzles teach you to think rigorously.

This site is where I document what I build and learn backend systems, API design, architecture decisions. It's part journal, part playground. I write to clarify my thinking and to share pragmatic lessons.

Experiences

• Student (Cloud Computing) — Bangkit Academy (2024)
  Learned to design and deploy scalable applications on Google Cloud. Worked in a team to build an AI-based app that recommends vacation destinations.
• Practicum Assistant — Muria Kudus University (2024–2025)
  Assisted students in understanding networking concepts, including configuration, socket programming, and protocol design using Python.
• Fullstack Web Developer Intern — PT. Pura Barutama (2025)
  Built and maintained a transaction management web app using CodeIgniter 4, jQuery, and PostgreSQL.

Projects

• Golem
  A Go-based minimalist load balancer for distributing traffic across multiple service instances with health checks, streaming support, Docker containerization, Prometheus, and Grafana monitoring.
• Madkhal WIP
