Mobile App Developer & Consultant

I build and improve apps for Android and iOS.

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.

How I can help

App development

Build a new app

Turn an idea into an Android and iOS app, from planning and interface design through development and release.

Discuss a new app

App improvements

Improve an existing app

Fix bugs, finish features, modernize older code, and make the app easier for your customers to use.

Discuss an update

App maintenance

Keep your app up to date

Keep your app working through platform updates, ongoing fixes, and new releases.

Discuss ongoing support

I 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.

How we’ll work together

  1. Discuss the project

    Tell me what you want to build, who it’s for, and where things stand today.

  2. Agree on scope and milestones

    We’ll define what needs to ship, how we’ll review it, and what it will take to deliver.

  3. Build, review, and release

    I’ll share progress and working builds so you can give feedback before launch.

What people say about working with me

“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.”

Kambi VictorCTOTajji Real Estate

“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.”

EmmanuelFounderCity Homes Kenya

“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.”
