Summary
👤
Senior🎓
Top SchoolRoark Innovations (Daniel) is a pragmatic engineering leader and serial founder with 11 years of experience building mobile-first products and teams across Android and Flutter. As Co-Founder & CTO of Roark (YC W25) he’s now applying that mobile expertise to analytics for voice agents, after leading Android launches and Flutter initiatives at companies like Casumo, Akiflow and several startups he co-founded. He combines deep hands-on skills in Kotlin, Jetpack, Flutter and backend services (Go, Mongo, Firebase, Kubernetes) with a track record of shipping full apps end-to-end as the sole or lead engineer. Comfortable moving between product, design and infra, he’s repeatedly turned prototype ideas into production apps—often integrating chatbots, gRPC/websockets and ML-backed conversational systems. Based in the San Francisco Bay Area but forged in Malta’s startup scene, he brings founder grit and a taste for elegant mobile UX.
