INDEPENDENT SOFTWARE ENGINEER

Building real-world software across Web2, Web3, AI automation, and hardware engineering.

Full-Stack Web2 / Web3 Developer

ABOUT

Information Systems undergraduate at Gunadarma University and an independent software developer. I work across Web2, Web3, AI automation, and hardware engineering — building practical, real-world systems from concept to implementation.

I'm comfortable developing products independently. From initial architecture decisions to the final deployment, I focus on shipping systems that solve tangible operational problems rather than chasing trends.

PHILOSOPHY


"Build useful systems."

"Learn by shipping."

"Connect software with real operational needs."
