Paul Waweru

Hi, I'm Paul. I'm a Senior Mobile Engineer with 11+ years of experience building software for venture-backed startups, scaleups, and large organizations. I'm currently at one of the top 5 banks in the UK, and I've shipped products at Medidata, Bulb and Onmo.

My expertise is building mobile apps, especially the small interactions, animations, and product details that make software feel fast, elegant, and useful. I've worked deeply with SwiftUI and React Native, and I've also built full-stack web and backend applications. I use Codex and modern AI coding tools as part of how I design, build, and ship.

Taste, to me, is how an app makes you feel. It's the small micro-interactions, the haptic feedback, and the way everything looks and feels together that helps people connect with it, remember it, and want to come back.

That shows up most clearly in the apps I build for myself. ReminderOS is a more personal reminders app for iOS, with flexible repeat schedules and workflows I wanted in my own day-to-day life. FrameOS helps app developers resize screenshots and screen recordings to match Apple's required dimensions, turning another personal workflow problem into a focused mobile developer tool.
