Projects
A selection of what I've shipped — real systems, real impact.
Fraud Detection Agent System
Async multi-agent system that analyzed 5,000+ calls in 100 minutes, tracking operator behaviors and false deal claims. Detected R$5M+ in fraud and eliminated the need for manual analysis.
Voice Platform — Debt Collection
End-to-end voice AI platform for call center debt collection. Covers audio preprocessing, Whisper fine-tuning, transcription post-processing, and a human evaluation loop for continuous improvement.
Monitoring & Quality Agent
AI agent that replaces human quality evaluation of calls with 90%+ accuracy. Includes a human feedback platform, dataset preparation pipeline, and fine-tuning loop.
AI Voice Agent — Operator Training
Simulates real client calls, scores operator performance in real time, and delivers structured feedback to accelerate training of new call center agents.
ML Pipeline Optimization
Migrated and optimized the full data pipeline from NiFi to Airflow, including audio preprocessing, Whisper fine-tuning stages, and transcription post-processing.
AI Governance Framework
Developed company-wide AI governance policy including PEAS framework mapping, model inventory tracking, and a defensive layered security model for AI systems.
