Stefanus Candra.
6+ years shipping high-scale native Android apps — reusable design systems, MVI architecture, and production release ownership.
About
I specialize in Android applications that work reliably in low-connectivity environments — a constraint I've solved in production at SawitPRO, where palm-oil field workers operate with inconsistent network access.
Across SawitPRO, Bukalapak, and Otomoto Indonesia I've owned the full delivery cycle: architecture decisions, design-system consistency, Google Play Store release management, and cross-functional alignment with product and QA teams.
What I do
Mobile Architecture
Design and implement offline-first Android architectures using Room, WorkManager, and sync queues — proven in production at SawitPRO where connectivity cannot be assumed.
Design Systems
Build and maintain shared Compose UI libraries that enforce visual consistency across app modules, cutting per-screen design inconsistency.
Release Ownership
Own the full Google Play Store release cycle — build signing, staged rollouts, post-launch monitoring, and rollback decisions.
Cross-Stack Contribution
Extend beyond Android when the team needs it — built the Sparca.id frontend with Vue.js and contributed to cross-functional product and QA alignment.
