Software Developer — backend services, APIs and cloud infrastructure
Barranquilla, Colombia
I build and maintain backend systems: HTTP APIs, background jobs and the infrastructure that runs them. Most of my work is in Python (FastAPI, Django) and .NET, deployed on AWS — often serverless, always with CI/CD and containers around it.
I care about the parts that show up six months later: clear boundaries between layers, tests that catch real regressions, and deployments that are boring to run.
- APIs and services — design and build REST APIs with FastAPI, Django and .NET, with a clean separation between transport, domain logic and persistence.
- Serverless on AWS — event-driven workloads on Lambda and managed services, sized to keep cost and cold starts predictable.
- CI/CD and automation — GitHub Actions pipelines that lint, test, build containers and deploy, so releases don't depend on anyone's laptop.
- Data layer — relational modelling on PostgreSQL and MySQL: schema design, migrations, and queries that stay fast as tables grow.
