I’m a Senior AI Full-Stack Software Engineer with 10+ years of experience building scalable cloud-native platforms and AI-driven applications. I combine modern full-stack delivery with practical AI engineering—especially LLM systems designed for clarity, safety, and real-world use.

Since 01/2023, I’ve shipped clinician-facing TypeScript + React/Next.js features for citation-first answers and follow-ups, optimizing perceived latency and response clarity for high-stakes APIs. I architected secure clinician sign-up, login, and RBAC flows using Next.js, Node.js, PostgreSQL, Redis, and OAuth/JWT, adding audit logs and admin tools for compliant access control.

On the AI side, I implemented RAG-based retrieval across 35M+ clinical workflows and developed Python-based AI integration services for model routing, prompt/tool orchestration, retrieval adapters, and deterministic fallback behaviors. I also integrated safety patterns for medication queries using 3,200+ drug monographs to enable refusal and no-answer behaviors when evidence is insufficient.

Earlier, at Airbnb (10/2018–12/2022), I delivered the Split Stays UI in React + TypeScript and improved search performance through lazy loading, code splitting, and prefetching. I also built and operated booking/checkout microservices and event-driven workflows, deploying on AWS and Kubernetes with Terraform CI/CD, canaries, rollbacks, and traceable releases.
