Why work with me

-
Remote-ready
Working remotely since 2023, both full-time and freelance. Based in Jakarta (UTC+7), with working hours that overlap Asia, Australia and Europe.
-
Work directly with the engineer
You talk to the person who writes the code, with no layer of sales or project managers translating your needs.

Grounded in computer science, not guesswork
Master of Computer Science with research in data and blockchain, and three journal articles. A good fit for non-standard requirements.
