Phi L.

Senior Software Engineer - AI-Driven Developer

Senior Software Engineer with 10+ years building and shipping production web systems — full-stack across React/TypeScript frontends, Node.js backends, and cloud infrastructure (AWS/GCP). Lately I’ve been deep in AI-assisted product work: designing LLM pipelines, structured outputs, and quality gates so model-generated results are safe enough for real users — including healthcare/HIPAA contexts. I’m comfortable owning a feature end-to-end: API design, UI, data, deploy, and debugging existing codebases. What I usually bring: - Strong JavaScript/TypeScript, React, Node.js, and PostgreSQL/MongoDB - Production LLM integrations (Anthropic, AWS Bedrock) and AI-native development (Cursor, Claude Code, Copilot) - Monorepo/build systems, CI/CD, and cleaning up complex legacy apps so they ship reliably Open to full-stack / AI engineering roles
