Shipping LLM platforms
and production infrastructure.

I build LLM-powered applications and the backend infrastructure underneath them. At AlphaSense, I helped ship Alphred — a GenAI Q&A system over earnings calls and financial filings — and built the high-throughput REST APIs powering its search layer. At NASCAR, I architected serverless Lambda/SQS pipelines and connected Adobe Experience Platform to LLM-assisted workflows serving millions of fans, backed by Datadog observability and quality gates that keep releases reliable. Seven-plus years of corporate engineering across AI, AWS, and full-stack development, with the backend depth and production instincts that applied AI roles require.

Applied AI & LLM Platforms

Production experience with LLM APIs, RAG pipelines, prompt engineering, and agent workflows — shipped at AlphaSense and NASCAR.

AWS & Cloud Infrastructure

Lambda, SQS, S3, CloudFront, EC2 — event-driven serverless architecture and infrastructure that holds up under real load.

Backend & API Design

REST API contracts, database schema design, and backend services built to be extended — not just to ship once.

Quality & Observability

Datadog dashboards and alerting, CI/CD quality gates, and integration/regression testing that keep releases reliable.
