Web & Mobile Developer
Hello, I'm
Enrico Irawan
I build ticketing and payment systems that thousands of people use every day — on the web, on their phones, and on the terminal at the counter.
About
Software that costs money when it breaks.
Four years on ticketing and payment systems for Indonesian banks, ports and public markets — the kind where a dropped form field costs someone their seat, and a frozen terminal costs a trader their day.
