What I Do

At Verzel (AI Developer — Lunella/RosanaDesk SaaS):

  • Architected event-driven serverless system on AWS: API Gateway → SNS → SQS FIFO → Lambda → EventBridge — 9+ microservices in production
  • Built Python ML/NLP pipelines on AWS Lambda for topic extraction and classification from conversational data, with multi-tenant consolidation and automated PDF/Slack reports
  • Integrated LLM agents (TaskingAI) and voice assistant pipeline (VAPI — STT→LLM→TTS)
  • Reactive Java backend: Quarkus · PostgreSQL · Redis · Keycloak · Flyway

Research (two master's degrees in progress):

  • UFABC — adaptive control (LQR, H∞), fault detection (EKF/UKF/CUSUM), LLM agent supervisor (CrewAI) in Hardware-in-the-Loop
  • UFPA — model-free predictive control and Deep RL/DQN for power electronics
