Hi, I'm Olumide (Lums), a low-ego, high-impact Product Design Engineer who turns complex problems into clear, useful experiences.

Over the last 6+ years, I've designed across fintech, SaaS, ecommerce and enterprise software, working on everything from banking and lending to payments, internal tools and design systems. I care about the full product, not isolated screens: how it works for users, how it supports the business, and how well it translates into something engineering can actually ship.

I'm curious by default and collaborative by nature. I ask a lot of questions, challenge assumptions and like working with people who bring different perspectives to the table. These days, AI is also deeply embedded in how I work, from research and ideation to prototyping, design systems and production-ready builds. The goal is pretty simple: understand the problem, make the work better, and get useful things shipped.

Words from people I've built with

  • Lums is not a pixel pusher. He is an AI-native builder with a designer's eye and a PM's brain — and that combination is exactly what product teams need to stay relevant in 2026. He specialises in taking an abstract problem, dissecting it surgically, and creating something better than what you imagined. Beyond the work — he is a generous collaborator, a fun teammate, and someone who makes the people around him better.
