Hire the Best Groovy Developers & Programmers
in Argentina

I am a software designer and developer. I've been programming for 20 years. More than 10 years of working remotely I know several programming languages, DBs, CI/CD tools, etc. I am very experienced in API integration (Slack, Bitbucket, Jira, OpenAI, Jenkins, AWS, and more) Currently, I develop back end micro services in Python using FastAPI under Linux / Kubernetes.

I'm a software developer specializing in backend systems, integrations, and cloud infrastructure, currently working as a Software Engineer at a consulting firm where I build integrations between platforms like Ramp and ERPs (SAP, Odoo, Salesforce) and maintain Azure-based cloud infrastructure. Previously, I contributed to an open-source Python library providing a RAG pipeline and document parsing utilities, developing core modules and companion automation tooling. I work across Python, Java/Kotlin, Elixir, JavaScript, and Go, with production experience in Flask/Django, Spring Boot, Phoenix, React, PostgreSQL, and Docker. I'm also comfortable integrating AI into real products — I've built LLM-powered features for repository analysis and automated assistants. I'm also a Teaching Assistant at the National University of Quilmes (Data Structures and Persistence Strategies), where I'm finishing my Computer Science degree, and I recently built Vela, a self-hosted container deployment platform (FastAPI, React/Vite, Traefik, GitHub OAuth, full test coverage with pytest and Playwright). I care about clean, well-tested code and clear communication — happy to jump on a call to scope your project.
