I'm a Computer Science Engineer with 6+ years of experience, working as a 100% remote freelance Fullstack Developer.
I build the systems small businesses run on: invoicing, inventory, cash register and customer management — designed to keep working when the connection doesn't. My flagship product, CajaYa, is a management SaaS for Cuban small businesses (mipymes), live in production. I've also shipped an ecommerce platform and production websites for real-estate and logistics clients.
My stack: React, Next.js and Angular on the frontend; NestJS, Express and Django on the backend; PostgreSQL with Prisma and Supabase for data.
My unfair advantage: before going fullstack, I spent 4 years as a Senior Infrastructure Engineer (enterprise environments, 100+ VMs). So what I build, I also deploy, back up and operate — Kubernetes, GitOps, CI/CD and observability included. You don't get an app that "works on my machine"; you get a system running in production and maintained.
I work per project or per hour — freelance/contract only — with clear deliverables and direct communication in English or Spanish. If your business still runs on spreadsheets and notebooks, let's talk.
