I build products, and the communities around them.

Today I’m a tech consultant in data and AI at RSM Indonesia in Jakarta, where I work on client projects from stakeholder interviews and user testing through to prototypes and project reporting. Alongside that, I lead the marketing, creative, and community teams behind TechFusion’s programs and hackathons, and I’m part of the committee that runs community events for Apple Developer Academy alumni.

My path started in IT support and sales, ran through growth marketing and web work at AIESEC, and led to the first Apple Developer Academy in Bali, where I worked on five iOS apps, including BlockMiners and Quiby. After the Academy, I shipped Dokum to the App Store on my own.

Here’s what I’m up to this month.

What I do

Product management
Discovery and user research, PRDs and roadmaps, and sprints ranked by evidence, from first idea to App Store launch.
AI prototyping
Building working prototypes with LLMs, then comparing approaches to find the one that holds up.
Programs and community
Events and hackathons, from budgets to the day itself, and partnerships with tech companies to grow them. The alumni events I’ve helped run average 200+ sign-ups.
Growth and analytics
Website, SEO, and funnel work, measured in Google Analytics and Search Console. On one national website, that meant 20% more traffic and 10% more conversions.

Away from the desk

Outside work, I’m part of my church community and play badminton. The rest of the time, you’ll find me hanging out with friends or catching a sunset. I ran my first 5k in 2025. I enjoy multiplayer games too, like Valorant, CS2, and Teamfight Tactics, though it’s been a while since my last match.
