01About

I take systems from idea to production and keep them running. Most of my work is the software that businesses run on: internal tools, CRMs and the modernisation of old processes.

I have built client websites as a freelancer, contributed backend features to a Discord bot for two and a half years, led a small team on a CRM in Dubai, and taught Python to university students.

I study Computer Engineering at Deusto and I am drawn to secure-software work: reliable, hardened systems that hold up in production.
