About

Professional summary

I am a junior full-stack developer based in Vila Nova de Famalicão, Portugal, transitioning from several years of customer service, sales, back-office, and delivery experience into software development.

I build web applications using React, Next.js, Node.js, TypeScript, JavaScript, PHP, Python, and MySQL. My recent work includes a production platform for a real client with an online store, secure authentication, and an administrative dashboard.

I have developed portfolio projects including a football quiz application with JWT authentication and dynamic leaderboards, a PokerStars hand-processing application with a PySide6 interface, and a PHP content management system with CRUD functionality and security measures.

My background in customer-facing roles has strengthened my communication, problem-solving, and service skills. I bring this practical perspective to building useful, user-focused software.

I hold a Full-Stack Web Developer certification and have completed programming training in Python. I am continuing to develop my technical skills through hands-on projects and production deployments.
