Freelancer Overview

Full-Stack Developer with 4 years of freelance experience specialized in the Angular + Node.js + TypeScript ecosystem. I build production-ready web applications end-to-end, including real-time systems with Socket.io, authentication with JWT, and MongoDB-based data layers. I use AI tools (Claude, ChatGPT) as part of my daily workflow, which gives me hands-on perspective on model output quality, edge cases, and where LLMs succeed or fail at code generation tasks. Currently completing a University Programmer degree at Universidad Nacional de Tucumán.
