About
Who I am, where I've worked and what I've studied.
I'm Ibnu Batutah, a Jember-based Mobile Engineer from Indonesia who has been building Android and iOS apps since 2021. I specialise in Flutter and native Android with Kotlin, and I've shipped everything from an e-commerce app with 100,000+ downloads to an offline-first health app used by community health workers in rural Papua.
My focus is building apps that still hold up long after launch: clean architecture, code a team can keep extending, and performance that works on low-end phones and weak connections. I care as much about the developer maintaining the code a year from now as the user tapping the screen today.
Teaching keeps me sharp. I joined Google's Bangkit Academy as an Android mentee, then came back as a mentor and guided 25 mentees to a 4.92/5 rating. That habit carries into every project: clear communication, honest estimates, and leaving each codebase and team a little better than I found it. Beyond mobile, I build backends with NestJS and Golang, and I'm currently exploring how AI can make mobile apps smarter.
Best regards,
Ibnu Batutah
