Founder profile
Naufal Hilmi Abdurrahman
Web Developer and Software Engineer, Surabaya
The engineer behind Aufal Tech. More than six years designing, building and deploying enterprise web applications and freelance projects, from banking software to language learning apps.
Summary
Full-stack, from the interface down to the server.
Naufal works across the whole stack: front ends, REST APIs, database design, CI/CD pipelines and the servers they run on. That range comes from years of being the person who both ships a feature and gets called when it misbehaves in production.
He has worked for local and international clients, inside Agile and Scrum teams and independently. Aufal Tech is where that experience now goes: software designed and released under his own name.
