Senior AI Product Engineer
Austin, TX
I build production AI systems for healthcare. I solo-engineered a clinical AI platform from zero to production — 10 integrated modules, hybrid RAG pipeline over thousands of curated medical papers, self-hosted medical LLM, and healthcare regulatory compliance (HIPAA/LGPD-grade). Currently serving physicians in clinical pilot.
Before engineering, I spent 7+ years in M&A and venture capital, including a successful founder exit (acquired by the largest PR conglomerate in Latin America) and portfolio value creation for a R$1B+ AUM fund. This combination of hands-on engineering and business thinking is how I build AI systems that are technically rigorous, economically viable, and regulation-ready.
Production clinical AI platform for physicians. The doctor asks a clinical question in natural language and receives an evidence-based response with verified citations in under 2 seconds. Accessible via web and WhatsApp.
What I engineered: Hybrid RAG (BM25 + semantic + Reciprocal Rank Fusion) with zero citation hallucinations. Self-hosted medical LLM (AWQ quantized) with 4-model fallback chain achieving 80–95% cost reduction. 5-layer safety system with PII scrubbing, drug interaction checks, and regulatory disclaimers. 10 modules: clinical chat, lab interpretation (22+ analytes, deterministic classification), ECG analysis (ResNet-1D trained on 345K Brazilian ECGs), ambient clinical scribe (Whisper + speaker diarization), adaptive quiz engine (1,053+ real exam questions), spaced repetition flashcards (ts-fsrs), interactive clinical cases, scientific library, WhatsApp channel, and gamification.
The AI infrastructure layer behind DocMinds. Proprietary model built on MedGemma, PaliGemma, and other open-weight foundations, fine-tuned with real Brazilian clinical interaction data. Five-layer safety agent, structured clinical knowledge fabric (national protocols, drug formularies, diagnostic codes, epidemiology), and data sovereignty — all processing on Brazilian soil.
Self-hosted LLM RAG Pipeline Healthcare Compliance Data SovereigntyPortfolio growth and value creation for R$1B+ AUM fund platform. Sourcing, due diligence, governance, crisis PMO. Notable outcomes: Neoway exit ~$360M (B3), Grão Direto seed-to-Series B ($0.46M to $15M).
Venture Capital M&A Portfolio OpsBuilt white-label orchestration platform automating campaign workflows. Clients included Uber, Rappi, Airbnb, Spotify via agency partners. Successfully exited to the largest PR conglomerate in Latin America.
Founder Exit SaaS AutomationProduction-grade RAG combining BM25 + semantic search + Reciprocal Rank Fusion with authority boosting and recency weighting.
Post-generation citation verification for RAG systems. Eliminates hallucinated references before they reach users.
Smart LLM routing with automatic fallback, complexity scoring, and cost optimization. 80–95% cost reduction vs single-model.
