Gabriel Martins

Thomson Reuters Brasil

Working within a cross-functional team of developers, QA, and product on an enterprise accounting office management platform serving customers across Brazil at one of the world's leading information services companies. Actively involved in migrating legacy Angular and C#/Java services to a modern React and Node.js stack, applying clean code and clean architecture principles throughout. Contributes across the full stack — REST API development, frontend interfaces, and unit test coverage.

Didows

Allocated at Ingresse — one of Brazil's largest event ticketing platforms — developing high-impact features relied on daily by event producers across the country. Given the nature of the business, zero-downtime and bug prevention were critical priorities, as any disruption directly affected producers' ability to run their events. Built two internal Design Systems from scratch (Material-UI and Radix UI/shadcn), standardising UI across teams. Mentored 2 junior developers through code reviews and pair programming sessions, helping to improve overall delivery quality.

CodeHouse IT

Joined an already live product — a multi-payment store management platform enabling business owners to process sales regardless of payment method. Developed new features and maintained a microservices backend with NestJS, a ReactJS web application, and a React Native mobile app, while ensuring production stability through ongoing support and unit testing.

4Map IT Consulting

Contributed to a bill payment platform for partner business owners to pay utility bills (water, electricity) powered by in-house machine learning. Worked within a layered MVC architecture and participated in training the internal AI model alongside backend development.

Grupo FCamara

Participated in a cloud migration project moving partner company services from AWS to Azure. Analysed codebases written in multiple languages, identified compatibility issues, replaced and refactored legacy code, and adapted existing tests to the new infrastructure — gaining broad exposure to multi-language systems and cloud platform differences early in my career.

GiftMe

Built a dynamic wish list web application from the ground up — a Node.js/Express REST API backed by MongoDB and PostgreSQL with Sequelize ORM, transactional emails via Google SMTP and Handlebars templates, and a React Native mobile app with Redux and Saga for state management. The mobile app was fully prepared for store submission but was not launched after a competing product reached the market first.
