The engineer behind JVC
John Ugonabo.
I build mobile products.
Senior iOS engineer operating through JVC. I take on mobile builds end to end, from concept and architecture to App Store, for startups, teams, and founders who need it done right.
About Me


I'm an iOS engineer who's fascinated by turning complex ideas into polished apps that people actually enjoy using. Over the past six-plus years, I've built and shipped production mobile applications across enterprise platforms and startup products, working with teams at Microsoft, HSBC, and several high-growth companies.
I think about engineering the way I think about everything else, from both a technical and strategic lens. I care about whether code is structured well, and I care just as much about whether the product communicates clearly and creates the right experience for the people using it.
Recently, I've been deep in AI-native development workflows, building custom agents and tools that multiply engineering velocity without sacrificing quality. Mobile product development powered by intelligent tooling is the intersection I'm most excited about right now.
Off the laptop, you'll catch me trail-walking, on the court, or digging into something I'm reading. I bring that same energy to my work by iterating fast, learning continuously, and leaving every codebase better than I found it.
