At Just Travel Tour, I built the Voucher Único MVP from scratch to production as part of a three-engineer team. The rechargeable digital card gives tourists access to local tours and attractions, with dedicated interfaces for tourists, the municipality, operators, and Just Travel.

I designed and implemented its React and Node.js application, backend architecture, APIs, and PostgreSQL database, then deployed it to GCP using Docker. I also helped evaluate agentic development practices, using an AI-assisted workflow with Cursor, Playwright analysis, and automated pull request reviews.
