React Native engineer at BILDIT who migrated El Palacio de Hierro’s app updates from CodePush to Expo Updates.

Indonesia

Message

At BILDIT, I built and customized El Palacio de Hierro’s React Native e-commerce app from BILDIT’s sample app. I also contributed to CMS and sample-app development so the retailer could update homepage banners remotely.

I migrated the app’s over-the-air update delivery from CodePush to Expo Updates and improved long-session performance by preventing duplicate, image-heavy screens from accumulating in navigation. I led a four-developer team while contributing hands-on to development, integrations, and delivery.

At OnTracka Australia Pty Ltd, I designed and built a configuration-driven survey system for a research-focused mobile application. At PT Solusi Hijau Indonesia (Smash.id), I provide technical leadership across web, Android, and iOS products and contributed to Adipura and SIPSD.
