About
Full Stack Engineer with 3+ years of experience building products that have generated over ₦35m in revenue and are used by 15,000+ users, across B2B and B2C domains. I specialize in TypeScript, React, and Node.js, with experience in leading engineering teams, system design, and DevOps. I’ve helped companies like LaborHack, Peppermint and Wynk Limited turn complex business problems into scalable products that drive growth and efficiency — from AI-powered systems for blue collar workers, to external APIs for third party integrators and platforms that enable data-driven product development for top companies like Kuda. I care about shipping high-quality software, collaborating across teams, and building products that make real business impact.
