About me

JUAN MARTÍN DE ROSA

Full Stack Web Developer & Automation Specialist

I'm a web developer specializing in React and TypeScript, with experience creating applications and websites. I also work with Node.js, service integrations, and automations, which gives me a more comprehensive view of projects and how to connect each part of the solution.

I've participated in the development of landing pages, websites, and web applications connected to both proprietary and third-party APIs, always prioritizing performance, maintainability, and a seamless user experience. Furthermore, my previous experience in e-commerce and digital marketing has given me a more product-oriented perspective, focused on conversion and business objectives.

I adapt easily to different teams and work dynamics, maintaining clear communication and a practical approach to problem-solving and efficiently managing projects.
