CAREER

Where I’ve worked.

  1. OPay logo

    OPay

    Junior Software Developer · 2020 – 2022 · Lagos, Nigeria

    In 2020 I won the OPay Hackathon, which was open to every developer in Nigeria. The win put my name in front of the Nigerian tech community. I applied to OPay soon after and joined as a junior software developer. There I learnt what it means to ship software millions of people trust with their money every day. I still work by what it taught me: ship carefully, listen closely, keep it simple.

  2. Torre.AI logo

    Torre.AI

    Full-Stack Software Engineer · 2022 · United States · Remote

    At Torre, I worked on Torre ATS and Torre Genome — recruiting and talent technology used by companies and professionals around the world. Scala and Play on the backend, Vue on the front. I saw how good data and good matching can change the course of a career.

  3. VeendHQ logo

    VeendHQ

    Lead Mobile Developer · 2022 – 2023 · Lagos, Nigeria · Remote

    I led mobile engineering at Veend, working with designers, product managers and backend engineers to turn ideas into apps used across Africa. Quick loans, transfers, bill payments and card services, plus a dashboard that lets lenders fund and track loans in real time.

  4. CHB Technologies logo

    CHB Technologies

    Full-Stack Software Engineer · 2022 – Present · Switzerland · Remote

    With CHB Technologies, I build and maintain enterprise software across backend services, web apps, mobile products and ERP systems. It’s the kind of work nobody tweets about and everybody relies on, systems that have to be right, every day.

  5. EasySpend logo

    EasySpend

    Lead Full-Stack Developer · 2025 – 2026 · Lagos, Nigeria · Remote

    From 2025 to 2026, I led the team that built EasySpend, working closely with product and leadership on a secure, scalable fintech product. We shipped USD and Naira virtual cards, instant loans, transfers, and electricity and cable payments, all in one app for iOS and Android.

  6. Marginplus logo

    Marginplus

    CTO & Co-Founder · 2024 – Present · Abuja, Nigeria

    As co-founder and CTO, I lead technical strategy and product at Marginplus, a platform for investing in real agribusiness across Africa, starting in Nigeria. We connect investors directly with vetted farms. I built the web and mobile platforms, and the architecture that keeps them reliable.

  7. SellWela logo

    SellWela

    CTO · 2025 – Present · Lagos, Nigeria · Remote

    At SellWela, I lead the technical vision and built the whole platform, web, mobile apps, backend, APIs, and the admin dashboard the operations team runs on. Retail stores, restaurants and online sellers use it to manage sales, inventory, orders and profit, online and in-store.

  8. Hire Africa logo

    Hire Africa

    Building the platform · Now · Remote

    Every product in this story was built with brilliant African engineers, designers and operators. Too often, the world never finds them. At Hire Africa, I’m helping build the platform that changes that — screened professionals across 31+ countries, hired directly.
