📍 Buenos Aires, Argentina
I'm a Programming Technician and UTN Programming student, focused on backend development and building reliable, maintainable software.
My main stack is Node.js + TypeScript, with experience building REST APIs, working with relational and NoSQL databases, implementing business rules, authentication, authorization and automated testing.
I enjoy understanding how things work under the hood, exploring software architecture and turning requirements into working applications. I also use AI as a development tool to explore codebases, investigate problems and improve my workflow — while validating solutions through tests, code review and execution.
- AI-assisted development: using AI to explore implementations, investigate bugs, review alternatives and identify edge cases.
- Testing & quality: unit, integration and end-to-end testing, regression prevention and automated quality checks.
- Software architecture: SOLID, separation of concerns, dependency injection and layered or hexagonal architectures where appropriate.
- Backend engineering: REST APIs, authentication, authorization, data consistency and business rules.
- Continuous learning: building projects, studying fundamentals and exploring new tools through practical experimentation.
AI can accelerate development. Understanding the code and verifying its behavior remain essential.
