Shipped native vector search and Bedrock ML integrations at Redshift scale. Won org-wide Amazon AUTA AI Hackathon (800+ interns) for a multi-model cost-aware router.
Twenty enterprise scenarios in openai/evals format plus three novel evals the public corpus does not cover: tool-use trajectory, streaming-cancel JSON validity, and PII leakage through tool arguments. Cross-model: Sonnet 4.6, Opus 4.7, GPT-4.X.
Reference implementation of a multi-agent enterprise assistant: one orchestrator, three specialist workers, Postgres Row-Level Security as the data-side guardrail. Live demo deployed on Fly.io.
Reproducible benchmark comparing Replit Agent, Cursor paired with Claude Sonnet, and the raw Claude API across 7 real-world development tasks. One command to run, pinned model versions, open scoring rubric.
Browser agent on Playwright and CDP, driven by Claude Sonnet 4.6 with tool use. Each proposed action classified by payload content before dispatch, so permission scope depends on what the agent is about to do, not just where.
