Senior DevRel Engineer @ Serverpod Google Developer Expert, Flutter & Dart

A career spent empowering developers.

I'm Jamiu Okanlawon. 9+ years in tech, 7+ years shipping production Flutter apps, founder of FlutterBytes, the community behind Africa's first Flutter conference. I build, I teach, and I gather people around the tools they love.

Chapter 1 · The builder
Shipped production Flutter apps for 7+ years

From a mental health platform at HavenHealth to fintech at Redbiller, where I owned the full mobile lifecycle and mentored a junior engineer who is now a senior. At Talabat, I rebuilt the order checkout flow in Flutter as part of their native-to-Flutter migration. And over three years at OneRoof, I helped grow the app into more than 100,000 active users, shipping features and raising the bar on quality along the way.

Chapter 2 · The gatherer
Built a community, then gave it a stage

FlutterBytes is a community of 776+ Flutter engineers, and the conference it produced is the first of its kind in Africa: 4 editions, 500+ engineers at each, and the 5th in planning. Members have gone on to land roles both locally and internationally. Beyond the stage, I run pair programming sessions to unblock members, review their architectures, and hold mock interviews. Watching mentees grow into senior engineers is the work I am proudest of.

DevRel for the full-stack Dart era

At Invertase I ran a one-person DevRel function for Globe: support, docs, starter templates, and Recall, an open-source full-stack reference app whose launch hit 6x typical reach. Google named me a Developer Expert for Flutter and Dart. Today I'm a Senior DevRel Engineer at Serverpod, teaching developers to build agentic-ready, full-stack apps with a single language. I also contribute to mobile development at the Human Development Fund.

Community

The mission: teach, mentor, and empower.

FlutterBytes is the center of it, but the work goes further: co-organizing Flutter Lagos, serving as a teaching assistant at the Google Cloud Roadshow in Abuja and Accra where 200 attendees got through their first cloud workshops, contributing to open source, and one-on-one mentorship that has carried engineers from junior to senior. Community members have landed roles both locally and internationally.

What people say

"Jamiu's dedication to the developer community is unmatched. Co-convening FlutterBytes with him has shown me firsthand how deeply he cares about raising the next generation of engineers in Africa."

What people say

"If not for Dev Jamiu, I genuinely don't think I'd have the level of skill I have now. He's a product person to the core—not a lot of software engineers extend their skills into product strategy and UX... Dev Jamiu is a blessing to the tech community and I'm a direct beneficiary of his benevolence."
