About
I'm Pablo, a software engineer in Madrid. I studied Computer Engineering at UC3M, with an exchange year at Florida Atlantic University, where I won the IBM Bluemix IoT hardware competition. In between I spent a summer in Rheda-Wiedenbrück, Germany, coaching youth basketball at DJK Rheda.
I started on C# and Java, then spent years on Rails and React before Solana pulled me in. The full list is on the work page.
Now I build multi-agent systems at Jupiter, and I publish notes as I learn.
