Languages, frameworks and tools I use to build production systems.
A sample of what I've shipped recently.
Built a foundational framework for AI agent communication at AWS Bedrock, defining standards, exploring agentic patterns, and integrating human-in-the-loop. Used LangGraph, LangChain, LangSmith, and Python for orchestration, tooling, and observability, setting the groundwork for advanced AI interactions.
Developed serverless, event-driven billing services for Apple/Google digital purchases, powering 16M+ annual subscriptions and processing 4.5M digital and 100k subscription orders monthly. These services scaled to handle 1.5M+ events/day, supporting 25% of Amazon's digital purchases and driving $184M+ in annual revenue.
Delivered user, group, and link-sharing features within SageMaker Unified Studio with a 5-person team. This project was showcased at AWS re:Invent 2024, significantly enhancing collaboration, permissioning, and governance capabilities across generative AI applications.
