Experience

I build systems for the company’s clients and products with .NET, React and data automation.

• Took the CRC Equipamentos work order system into production.
• Redesigned, for Datacar, the algorithm that matches each car offer to its entry in FIPE, Brazil’s vehicle price table. It ran alongside the old one to compare results and has been in production since October 2026.
• Cut the load time of the main screens of Datacar’s pricing platform from about 3 s to under 1 s, with half the requests (median in a local environment, warm cache; delivery under review).
• Maintained and improved, since my internship, 40 Datacar data collection bots and services, plus the platform that schedules and monitors them.
• Wrote 9 playbooks that guide AI agents in building bots to the team’s standard.

Web interfaces, bug fixes, refactoring and technical documentation, working in an agile team.

• Built from scratch, as the only developer, the work order system for CRC Equipamentos, an industrial maintenance company, replacing paper, Trello and spreadsheets.
• Built the admin panel and API for the PriceFleet website, a fleet pricing product, with login, permissions, blog, image uploads and lead management.
• Prepared and ran 2 internal AI training sessions for the company (harnesses and MCP).

Systems for my community and my own projects, from planning to deployment.

• Website for Primeira Igreja Batista em Lagoa Santa, now in production, replacing the old WordPress site.
• Inventory system for the church storeroom and the live website of its youth group, Salt.
• FIT.AI, a workout app with an AI assistant, live and open source.
• Website for the Recanto Vida care home, live, with hosting, domains and email under my care.
