Hi, I'm Francis.

I'm a 🇳🇬 software engineer with a strong foundation in backend and infra development and a passion for tackling complex challenges. I'm fascinated by distributed systems, databases, and functional programming, and I primarily work with Go and Haskell.

You can read more about me on my personal website. You can also check me out on BlueSky @codehakase.com or Twitter (X): @codehakase.
