Start from the desk, not the diagram
A village clerk, a teacher, a shop owner. The workflow they already have is the specification; the software should shorten it, not replace it with a new one.
Software that keeps Public services running.
I’m Muhamad Irga, a fullstack developer in Purwokerto, Indonesia. I build administrative and public-service systems for local governments, village enterprises, schools, and small businesses.

Three kinds of work
Records, operations, and classrooms.
Most of what I build replaces paper, spreadsheets, and WhatsApp threads with something the whole office can rely on.
Selected work
83+ applications since 2020.
These 21 are the ones worth opening — the flagship systems and the builds still running in production. Each documents its real workflows, implementation, and technology stack, with no case-study fiction. The rest is client work, internal tooling, and smaller commissions.
About
A Fullstack developer in Purwokerto.
My work covers administrative systems, public services, and the tools people use to run their organisations — mostly for Indonesian local governments, village enterprises, schools, and small businesses.
That means population records and document services one week, point of sale and accounting the next. The common thread is that someone has to use it every morning, so it has to be fast, legible, and correct.
Purwokerto, Central Java
Records outlive features
Population data, ledgers, and report cards have to stay correct for years. Schema, validation, and audit trails get the attention first.
Ship it, then stay with it
Most of these systems are live and in daily use. Deployment, backups, and the boring maintenance are part of the job, not an afterthought.
