Hi, I'm Zulkifli

Your Software Lab Partner

Fullstack Engineer & Coding Mentor

I build software end to end — APIs that hold up under load, interfaces that feel considered, mobile apps that ship, and the pipelines that carry all of it to production. Then I teach the engineers who take it from there.

The engineer behind the lab

Six years across the whole stack, and a stubborn belief that good software and good teaching are the same skill.

Senior software engineer with 6+ years building and shipping production systems for Indonesian government ministries, enterprises and startups — web, mobile and backend. I work across React, Next.js and Node.js, with Go, React Native and cloud infrastructure alongside. I've owned products end to end, from architecture through deployment, and shipped AI-integrated features into live workflows. For most of that time I've also been teaching: instructing full-stack cohorts at Hacktiv8, then leading curriculum and the instructor team.
