Full Stack Engineer | TypeScript, React, Node.js, NestJS, PostgreSQL
Buenos Aires, Argentina
I'm a fullstack developer with 4 years of experience. I work with React, TypeScript, and Node.js daily, and I use AI tools like Claude Code and GitHub Copilot as a core part of my development workflow, though I always review and validate the code they generate before it reaches production.
At Abstract, my most recent company, I was the technical lead for two client accounts. I took ownership of complete features: implementation, testing, deployment, and monitoring. I integrated RESTful APIs, JWT authentication, and worked with MongoDB and PostgreSQL depending on the project. I used AI for coding, refactoring, and debugging, and took part in CI/CD processes. I delivered over 10 projects, averaging 3 weeks per project.
At Notimation, I built UiTool, a drag-and-drop SaaS platform for creating PWAs, landing pages, and email templates. I designed AI-powered chatbots integrated into the purchase flow, as well as an A/B test on that flow that improved conversion. I also led the frontend of UiTrade, a trading platform, working with a team of 4: I made architecture decisions, set up code review processes, and we defined standards from day one. Within the first 6 weeks I delivered the MVP with full test coverage on critical components, and by month three, production bugs dropped significantly. I integrated third-party services, including payment providers and analytics, and worked with OAuth 2.0 and JWT authentication.
I also have two personal projects: LinkWorlds, a fullstack template platform, and OficiosClick, a marketplace for skilled workers where I handled everything: development, architecture, design, and branding.
I work remotely from Argentina, speak English at B2 level, and enjoy keeping up to date with new technologies, especially AI applied to development.
