Tomás Pérez Losada

I’m a Full-Stack Developer experienced in building web applications and AI-powered solutions using React with TypeScript, Spring Boot Java, Node.js, and REST APIs. I bring a user-focused mindset shaped by 8 years of B2B/B2C Customer Support experience, so I care about how products feel in real operational workflows. I’m also comfortable in bilingual English environments and bridging communication between customers and technical teams.

I built a multi-architecture e-commerce platform to solve the same business requirement across Vanilla JavaScript, React + Firebase, Next.js, and MERN. It includes user authentication, an admin dashboard, and a persistent shopping cart, with REST APIs powering catalog and business operations.

I also developed backend-focused work like a REST API for invoice management using Java, Spring Boot, and MySQL, including RESTful endpoints and API documentation. On the AI side, I created Jazzam, an LLM-powered music recommendation assistant using the Google Gemini API with prompt engineering and an interactive Streamlit interface, blending practical engineering with experimentation.
