Problem: moving money across borders is slow, opaque and overpriced. Responsibilities: architecture, stack decisions, delivery and technical leadership.

Jan 2022 - Apr 2023

Needer · FullStack Developer

I gathered requirements and built a multimedia marketplace with a social platform in Django.

Beyond the roadmap.

I'm a software engineer from Universidad Surcolombiana, based in Colombia. The same discipline that ships software shows up on the mat, in exams and at industry events: I train Brazilian jiu-jitsu and MMA, compete on the AJP Tour, and stay close to the industry building fintech and AI.
