Experience

2026 – present
Software Development Intern
Raposo Plástico
I work on the digital transformation of a plastics recycling company, building internal tools that organize the teams' work and cut down manual processes.
- FlowPilot: I build the company's internal platform for managing tasks and routines.
- Full stack: Vue 3 (Composition API) and Tailwind CSS on the frontend, and NestJS, TypeScript and TypeORM on the backend, with PostgreSQL.
- New features: I ship new functionality for the platform.
- Infrastructure: deploys on Railway with the database on DigitalOcean, plus planning and evolving schema migrations.

Undergraduate Research Fellow (Research & Development)
Federal University of Ceará (UFC)
- Wrote scripts for quantum circuit simulation and data processing.
- Worked in an academic team focused on solving mathematical and algorithmic problems.
Python, NumPy, Git
Jan 2024 – Dec 2024
Full Stack Developer and Project Manager
GTI (Junior Enterprise)
- Frontend: built responsive, dynamic interfaces with React and Tailwind CSS, turning high-fidelity Figma prototypes into working code.
- Backend: designed and built REST APIs with Node.js and Express.
- Leadership: as manager, I ran the Scrum ceremonies (dailies, sprints), keeping Git versioning in order and the project's features shipping.

Projects

Projects from my degree and of my own. Each one has open source code and a live version to try.

github.com/gabrimoreira/document-ocr-ai
AI-powered OCR platform
A full-stack app that extracts text from documents automatically. The frontend is Next.js, the backend is NestJS, and an AI integration summarizes each document and fills in fields such as vendor, dates and total amount.
Next.js, NestJS, TypeScript, AI
Open demo
github.com/gabrimoreira/lung-segmentation-web
Lung segmentation web app
A web interface for medical image analysis. Upload CT scans as DICOM files, run segmentation algorithms (Otsu, Watershed), edit the contours by hand and export the results. Built with React, TypeScript and shadcn/ui.
