Victor Fialho — 20 · Brasília, Brazil 🇧🇷
AI Engineering @ IESB (one of Brazil's first bachelor's programs in the field)
Founder @ AoTomate Sistemas

I don't just study automation — I build it, ship it,
and debug it in production for real clients.

Flagship AoTomate system: an AI customer service agent built for a remote secretarial company, live in production. End-to-end ownership — architecture, deployment, monitoring, and production debugging.

• What it does: answers inbound WhatsApp messages 24/7 in seconds, routes conversations per tenant, escalates to humans only when needed
• Engineering highlights:
  • Diagnosed and fixed a production-breaking change in Meta's remoteJid → @lid GUID format that silently broke message routing in Evolution API
  • Multi-tenant message routing with hardened Supabase RLS policies
  • Zero-marginal-cost inference pipeline — migrated from Claude API to Groq free tier
• Code: private (client production system) · architecture writeup available on request

STATUS: ● LIVE

Full-stack system built for a real organization (União Centro Oeste Brasileira). Complete order lifecycle — request → warehouse separation → shipment → delivery — with role-based access and photo evidence at each stage.

STATUS: ● LIVE

NLP pipeline for sentiment analysis in Brazilian Portuguese — classical ML from scratch, no pre-trained models. Corpus preprocessing → TF-IDF → Logistic Regression, with focus on PT-BR text normalization, class imbalance, and model interpretability.
