I build infrastructure for a living — and hold my side projects to the same standard.
15+ years designing secure, scalable cloud platforms for FinTech, Telecom, and global manufacturing teams. Outside the day job, I use the same standards — no dark patterns, no data collection, nothing you can't verify — to build small tools I actually needed myself: finance calculators, dev utilities, and a few apps that just made my own life easier.
Everything below is free to use and shows its work.
