A nail journal with inspiration boards, appointment planning, and care tracking.
I’m Lazarus Mugo. I help founders, small businesses, and product teams build new mobile apps, improve existing products, and maintain them after launch. You work directly with me from planning and design through development and release.

Work
4+ years shipping apps to Google Play, the App Store, Microsoft Store, and Snapcraft.
Fun
Rugby prop — XVs. Scrums on weekends, code on weekdays. (I naturally dislike Bronco Tests)
App development
Turn an idea into an Android and iOS app, from planning and interface design through development and release.
Discuss a new appApp improvements
Fix bugs, finish features, modernize older code, and make the app easier for your customers to use.
Discuss an updateApp maintenance
Keep your app working through platform updates, ongoing fixes, and new releases.
Discuss ongoing supportI also build websites and web interfaces that support your product.
I bring an eye for interface design to mobile engineering. I care about how an app feels to use and how easy it is for the next person to maintain.
Tell me what you want to build, who it’s for, and where things stand today.
We’ll define what needs to ship, how we’ll review it, and what it will take to deliver.
I’ll share progress and working builds so you can give feedback before launch.
Mobile · Kotlin, Kotlin Multiplatform, Jetpack Compose, Compose Multiplatform, and Swift for iOS bridging. Release automation for Google Play and the Apple App Store.
Desktop · Desktop apps built with Kotlin Multiplatform and Compose Multiplatform. Published to the Microsoft Store for Windows and Snapcraft for Linux.
Web · React, Next.js, Tailwind CSS, and TypeScript.
“Mugo is a sharp, capable engineer who picks up new technologies fast and applies them well. He joined as an intern and grew into our Chief Product Officer and mobile lead, a trajectory that says a lot about his drive and range. He's absorbed and put to real use things like OAuth, OIDC, SvelteKit, Kotlin Multiplatform, and Gradle in short order. It's been a pleasure working with him across design, web, and mobile. His instincts on security and architectural trade offs, especially as the app moved from early stage to scale, were a real asset. I'd work with him again without hesitation.”
“Lazarus delivered an exceptional platform that beautifully showcases our luxury properties. His frontend work with SvelteKit resulted in a fast, elegant website that our clients love. He's professional, creative, and consistently delivers beyond expectations.”
“Mugo is one of the best frontend developers I've worked with. His code is clean, maintainable, and always well-documented. The collaboration was seamless—he understands the full stack and makes integration effortless. I'd work with him again in a heartbeat.”
