Hi, I'm Donnovan.
Senior software engineer with production experience shipping LLM-powered applications, RAG pipelines, and event-driven AWS infrastructure — most recently at AlphaSense and NASCAR.
About Me
Shipping LLM platforms
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. 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.

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.
