Hi! I'm Cimar. My first production code wasn't at a bank: it was my thesis, a study-material sharing platform I built for UMSA's Faculty of Humanities. Before that I was already teaching programming fundamentals to first-semester students, where I learned that explaining something is the best way to truly understand it.
Today I work at Banco Bisa, where I build backend services and internal applications for the bank's operations.
Right now I'm all in on Go. I build REST APIs in my free time applying hexagonal architecture and DDD, and study how the language works under the hood: concurrency, internals, the parts most people skip.
