Fullstack developer crafting reliable, scalable web applications — from databases and APIs to refined, human interfaces.
Ibuildsoftwarethatsolvesrealoperationalproblems.
I'm a fullstack developer based in Tangerang, Indonesia, with a degree in Informatics from Universitas Multimedia Nusantara. I've worked across the stack at companies like BCA and Singapay.
I co-founded Hesed Tech, a studio shipping animation-driven web products — integrating payment gateways, tuning APIs, and cutting content-update time by 60%.
Whether it's designing APIs, tuning database queries, or crafting interfaces, I care most about building things that are reliable and genuinely useful.
