What I'm looking for

I seek a collaborative, growth-oriented team where I can build scalable web applications, take ownership of features, learn new technologies, and contribute to impactful projects.

I am a motivated and detail-oriented Full-Stack Developer with hands-on experience designing REST APIs, building React interfaces, and managing databases like MongoDB and SQL Server.

I have worked as a Full-Stack Developer and IT Consultant, contributing to projects for banks and enterprise clients, deploying web services, and configuring enterprise content solutions.

My academic background includes a Bachelor in Software Engineering from the Polytechnic Institute of Setubal, complemented by practical internships in electromechanics and automotive maintenance that strengthened my problem-solving and technical discipline.

I bring strong communication, teamwork, leadership potential, and a proactive mindset, committed to continuous learning and delivering high-quality, user-focused solutions.
