At Technomar Engenharia, I deliver end-to-end features for a production Vessel Traffic Service platform, working across React and TypeScript frontends and Python/FastAPI backends. I delivered five CRUD modules across frontend, API, and database workflows, and implemented radar image retrieval and visualization on the operational map.
At Nomad Digital, I contributed to modernizing legacy .NET/DotNetNuke applications toward PHP/Laravel and Vue.js 3, primarily developing the new frontend while making targeted backend changes. I also built a Vue.js 2 simulator frontend connected to an existing Node.js backend and onboard train equipment, reducing laboratory test cycles from approximately 40–60 minutes to around 10 minutes.
At Nomad Digital, I developed the event-driven DT4 Positioner service in Node.js using MQTT and operational inputs; it was deployed across approximately 120 trains in Hamburg. I also developed features for the Multimedia Application Server, enabling users to build and schedule multimedia playlists for passenger trains.
Across my work, I’ve contributed to business-critical enterprise applications, APIs, and data-driven systems, with a focus on software modernization, incremental improvement, testing, and production troubleshooting. My experience spans backend, frontend, integration, and data layers, including long-term work in Germany and collaboration across Brazil and Europe.
