Experience
- Roving HealthData / AI EngineerJanuary 2026 - Today (6 months)Built AI call classification on Claude (AWS Bedrock) for a hospital — ~600 calls/daycategorized by intent and quality, withschema validation preventing bad LLM output from reaching the database(an eval/guardrail at the write boundary). Owned the surrounding production system: event-driven ingestion (webhooks → API Gateway → SQS → Lambda classifier → RDS) with idempotency, DLQ failure isolation, and HIPAA controls (PHI masking, KMS, pgAudit, cdk-nag). Built GraphQL EHR integrations (Healthie) and a billing rollup engine for CMS-1500 claims. *Claude• · Python◦ · AWS Bedrock/CDK/Lambda/SQS/RDS◦ · Drizzle◦ · Postgres*
- SiasolaFounder & Lead EngineerJanuary 2024 - Today (2 years and 6 months)Built and operate a multi-agent orchestration framework — agent teams own tasks from research through execution and self-verification, auto-deploying above a 0.85 confidence threshold — reaching ~95% ideation-to-deploy autonomy across 9 concurrent projects. Built a 21-tool Model Context Protocol (MCP) server (Python, 2,260 lines) with an FTS5/BM25 search engine, cross-project constraint validation, and execution-trace logging — the context backbone the agents run on. Made evals first-class: a 6-layer confidence-scored verification gate per change. Cut LLM/inference cost 98% ($120→$2/mo) by self-hosting on serverless GPU; built a4-stage daily pipeline (3.75× speedup via asyncio). *Claude/OpenAI/Gemini• · Python◦ · TypeScript◦ · asyncio◦ · Convex◦ · Supabase◦ · Sentry*
