$ About Me
I'm a senior software engineer specializing in AI/LLM systems and full-stack delivery. I've been building production AI since 2019, including one of fintech's earliest LLM deployments, and I've since gone deep across the full applied AI stack: agentic pipelines, ML inference optimization, LLMOps, vector search, and security-hardened LLM middleware.
My career started at Intuit, where I shipped a Python LLM chatbot for QuickBooks and built the AI agent platform that cut CX support costs by 40% across QuickBooks and TurboTax. From there I led authentication infrastructure at EarnIn, deploying OAuth 2.0 and Passkey auth to millions of users. Most recently I've been building pay recommendation AI and an LLM compensation agent at Syndio.
When I'm not coding, you can find me exploring new technologies, reading books on science and history, or sharing knowledge through technical writing and mentoring.

AI Software Engineer
Syndio · Remote
Building pay recommendation ML API end-to-end: REST API design, async Pub/Sub + Cloud Functions inference pipeline, and multi-model Vertex AI predictions from a single endpoint, achieving 2-4x inference speedup. Migrated Vertex AI Vector Search to pgvector, eliminating managed vector service costs with no retrieval quality loss. Built PII redaction middleware using Microsoft Presidio + spaCy NER to satisfy enterprise compliance requirements. Architected an AI compensation agent with Google ADK and Vertex AI Gemini.
