Projects with technical context.

Selected cases with complete technical documentation: problem, contribution, stack, and implementation direction. The selection criterion is quality of execution, not volume.

Activo Own ProductMobile App 2026

Full Stack

Quadra

A mobile app to organize personal finances quickly and efficiently — helping users record expenses, income, and transactions with less manual effort through assisted capture, categories, budgets, and simple reports.

Problem

Many people stop tracking their finances because logging every expense manually takes time and becomes tedious. Quadra aims to reduce that friction with a fast, clear experience built for daily use.

Role

Product design, technical architecture, mobile development, backend, data modeling, and device synchronization.

Stack

    Flutter FastAPI Python PostgreSQL Firebase Auth SQLite / Drift

Key highlights

  • Fast recording of expenses, income, and transfers with accounts, categories, notes, and transaction history.
  • Modules for budgets, goals, debts, reports, and assisted capture to reduce manual entry.
Funcional Complexity Media 2025

AI/ML

Computer Vision Gesture Controller

Real-time hand gesture recognition system that translates hand movements into desktop actions using computer vision.

Problem

Explore a webcam-based hands-free interface and validate whether a heuristic approach over MediaPipe landmarks could sustain real-time interaction without a trained classifier.

Role

Academic project focused on applied computer vision.

Stack

    Python OpenCV MediaPipe NumPy PyAutoGUI

Key highlights

  • Real-time hand landmark tracking from webcam with visual feedback overlaid on the live frame.
  • Gesture classification through per-finger state detection and geometric distances between key landmarks.
