Zero-downtime search migration
Wayground · 2025–26
Moved a critical, unowned indexing pipeline into an owned, observable service and re-indexed
120M records with no maintenance window. Reads go through an alias, so cutover and rollback
are each a single atomic swap.

OAuth 2.0 + dynamic client registration for AI tools
Wayground · 2026
Led a cross-team build that opened the platform to ChatGPT, Claude and Superhuman over MCP.
Encrypted opaque tokens in Redis instead of JWTs so access can be revoked instantly, with PKCE
required for every client. Once registration existed, the Claude integration took under a week.

District intelligence for sales
Wayground · 2025–26
An agentic pipeline that verifies CRM contacts and reads public school-district documents
(board minutes, improvement plans) with OCR and LLM extraction. It produces structured signals
about curriculum needs, competitors and decision makers, and a dashboard the sales team used live on calls.

13-stage LLM content pipeline
Wayground · 2025
Took an ML proof of concept to production as a pipeline where every stage retries independently
over SQS. Cut LLM spend with model tiering and by replacing some LLM calls with rules. Separately,
reworked a core API with cursor pagination to bring P95 latency down 70%.

First-party intent
Apollo.io · 2023–25
Built one of Apollo's most-requested features end to end: resolving anonymous website-visitor IPs
to companies, aggregating intent signals, and indexing them beside a 256M-record search index
without touching it. Taken from proof of concept to production.
