I've led Flutter development and maintenance for consumer products at Catalyst Tech, including revamps of Jamtangan and voilà.id focused on performance, UI/UX, and maintainability.

Across freelance work and mobile development roles at Eisbetech and Supersoft, I've delivered mobile and web products using Kotlin, Swift, Flutter, Java, and React Native. My projects include Bythen.ai, Interbat, Finashowroom, Mobile Survey, Rumah Ampas, MIC Pay, Ikhwan Mart, PKSS, Waqara, Jalurangkot, Internusa, and 58Cell.

I also review iOS student submissions for Dicoding Indonesia, provide structured technical feedback, and support developer learning through advising, facilitation, and mentoring.
