About
I’m a software engineer based in Surabaya, Indonesia, and I’ve been building software for about ten years. Most of that time has gone into backend systems: chatbots, CRMs, REST APIs and, more recently, SaaS blockchain products and AI applications built with tools like LangChain. Along the way I’ve also led backend teams, reviewed a lot of code and mentored newer engineers. These days I work independently as a freelance software engineer.
This site is my personal notebook in public — a place to share essays, practical notes and the occasional reflection.
Currently writing here at least twice a week: notes from my software work, and thoughts on the books I’m reading.
Updated October 2026
Practical notes from building backend systems and working on engineering teams.
Shorter thoughts on work, learning and growing as an engineer.
Books and ideas worth sharing.
The best way to reach me is by email. I’m happy to hear from you about software, backend engineering or books.
