@joovitorhelm
I build scalable full-stack configuration platforms and lead cross-border engineering teams.
BrazilWhat I'm looking for
At TK Elevator, I led the Brazilian branch of the Product Configuration team as the primary technical liaison to the U.S. division. I developed, reviewed, debugged, and tested thousands of engineering rules, translating complex engineering documentation into JavaScript logic that supported faster elevator-model and market rollouts.
At UNA Tecnologia da Informação, I build and maintain a configurator tool for elevator sales, helping representatives generate accurate configurations and quotes without manual engineering review. I work across Vue.js, Vuetify, Groovy, Grails, APIs, microservices, and microfrontends while contributing to reliable production systems in a 20-person Agile team.
I also build end-to-end products with React, Next.js, Node.js, TypeScript, PostgreSQL, Prisma, Docker, and cloud deployment tools. I use AI-assisted development tools to understand unfamiliar codebases and review pull requests more efficiently.
