What I'm looking for

I’m looking for EU-based opportunities (on-site or remote) where I can build full-stack products and apply data analysis and machine learning to solve real problems, collaborating closely with teams that value clean REST APIs, strong engineering, and measurable impact.

I’m a Junior Full-Stack Software Developer focused on building full-stack platforms that turn real-world data into reliable decision support. At OPT (Planning and Transport Optimisation), I develop and maintain public transport network systems using TypeScript, .NET, and C#, while building React frontends and RESTful APIs for workflows supported by SignalR. I also clean and process GTFS datasets, using SQL, Tableau, and Python foundations to underpin operational and technical decisions, with applied machine learning always in mind.

My work is shaped by both product impact and technical rigor: during a Summer Internship at TecStorm, I produced an AI-powered clinical pre-triage prototype based on the Manchester Triage Protocol and built an AI-driven chatbot trained on structured GTFS data to support transport operators, earning 2nd Place – EBEC 2024 for interactive KPI dashboards. Earlier, my curricular internship included implementing a Kalman Filter in C++ and JavaScript to predict bus ETAs by fusing real-time GPS with static GTFS, delivering the project two months early; I’ve also built graph-based, heuristic approaches for optimization problems in project work. I’m currently strengthening my engineering foundation through a Bachelor in Computer Engineering and Informatics (University of Porto) and a Networks Engineering master track, and I stay grounded through mentoring and volunteering as a Buddy at FEUP.
