Why work with me

  • Full-stack ownership

    I take a feature from database schema to deployed interface, not just the frontend half.

  • Mission-critical systems

    Built and maintained software law enforcement and paying subscribers depend on daily.

  • Team leadership

    I currently direct 6 engineers, and I stay hands-on with the code while I do it.

  • Performance-minded

    Bundle size, load time, and query performance are things I measure, not afterthoughts.

I'm a full-stack software engineer with 5+ years shipping production software end to end, from Node.js backend systems to polished React and Next.js interfaces. I've led a team of 6 engineers, owned mission-critical systems used by the Nigeria Police Force, and been the sole engineer on a subscription product serving 8,000+ users. If you need someone who can take a complex requirement and turn it into shipped, reliable software without a lot of hand-holding, that's the work I do.
