Summary

In software since 2014, I started full-stack on MERN before spending more than a decade building Ruby on Rails projects end to end.

That work covers frontend, backend, admin dashboards, mobile apps with web views and native mobile apps, alongside Linux, server administration and Cloudflare edge infrastructure.

I have worked in the social-impact sector for more than a decade and shipped my own products throughout.
