About

I'm a software engineer who works across the stack — from API and database design through to the interfaces people actually use.

Most of my work sits in fintech and developer tooling: payment integrations, MCP servers, and shipped products like Mizizi, Grocery Hero, Luta Rentals, IvyBackup, and PayScale. I like building reliable software that solves real problems.
