At Digilivro, I developed a production web system from conception through deployment using PHP, React.js, and Python. I also developed mobile features in Flutter and Dart.
With the team, I helped structure a CI/CD pipeline with automated tests that reduced deployment time from a slow manual process to under one minute.
On Consórcio System, I built a document-processing system that converts PDFs into Excel spreadsheets. It cut processing time from 3–4 days to seconds for around 100–150 documents a month.
I also developed full-stack projects including Hivelancers, a freelancer marketplace with real-time chat and Stripe Connect payments, and Duelo, a real-time multiplayer quiz tested with up to eight simultaneous players.
