Hi šŸ‘‹šŸ¾ I'm Francis, a software engineer with 6+ years of experience. In the past I've built financial systems, compliance workflows, monitoring tools, and developer tools. I primarily work with Go and Haskell, and I'm mostly interested in distributed systems, databases, and functional programming.

Feel free to read about myself, look at my posts, or book a chat with me.
