Currently leading AI-native transformation for a North American digital bank — shipping RAG pipelines, LLM agents, and RPA automation to production on AWS with a 90-person team.

21 years across banking, fintech, edtech, and telecom.

What I've been building

  • Conversational banking agent — Amazon Lex + Bedrock (Claude 3) + RAG over OpenSearch + custom MCP server; auto-detects Spanish/English, deflects 45% of tier-1 queries
  • LLM-powered KYC pipeline — RAG-based document processing cutting compliance review time 65%
  • Voice agent prototype — LiveKit · Deepgram STT · AWS Bedrock · Cartesia TTS benchmarked for production readiness
