Lab
Interactive tools for data contracts, quality, AWS and backend delivery.
SELECTED WORK
Selected systems.
Operational AI agents
Internal agents that help engineers triage logs and diagnose pipeline errors in their existing workflows.
Domain-owned data platform
A self-service lakehouse foundation connecting ingestion, domain data products, contracts and governance.
AWS online feature serving
The AWS serving side of a lending feature store, connecting offline feature pipelines with DynamoDB-backed online access.
Data Contract Platform
Versioned contracts that align data producers and consumers on structure, meaning, and quality.
TECHNICAL BLOG
From idea to implementation.
AI Agents
One search experience. Current access at every boundary.
A shared search architecture for conversations and content: hybrid retrieval, governed ingestion, typed results and permission-aware release.
AI Agents
Build agent context that keeps its evidence.
An incident-assistant design exercise: bounded retrieval, evidence envelopes and checkpoints that preserve uncertainty.
