- Own the AI layer of NetworkChains, a live relationship-selling platform: social and messaging ingestion, identity resolution, a relationship model, signal detection, product opportunities and an agentic sales copilot.
- Measured 956 production recommendations and found the relevance score couldn't separate good from bad matches; replaced it with a per-item LLM judge allowed to say nothing fits, plus a separate writer, cutting forced product pitches from 100% to 8% and hedging from 83% to 0% on replayed cases.
- Built EarnGPT, a 5-iteration tool-calling copilot over a 7-layer context stack (relationship replica, memory slots, contextual retrieval with HyDE, document RAG) that skips raw RAG when the replica is fresh (estimated ~96K → ~2K tokens/turn); the reranker returns IDs only, so it can't mislabel products.
- Designed and built DeployMachine (Go, PostgreSQL, Next.js), which deploys open-weight LLMs with vLLM on NVIDIA and AMD GPUs in the customer's own cloud (DigitalOcean; AWS via a cross-account role), with a fit check before any GPU is bought. It now serves three models (27B FP8, 9B, embeddings) on one AMD MI325X to our production sales-assistant backend, falling back to Claude then OpenAI; an A/B on 30 real contacts kept extraction on the 27B (the 9B broke the schema 3/30).
- Synthesised each relationship from six sources with every claim cited and verified by exact match or ≥0.8 similarity; identity resolution auto-merges only on strong system-derived keys, so uploaded CSV ids can't poison identities, and merges are reversible.
- Mirrored the Garage catalog (9 item types) into Qdrant through a transactional outbox and HMAC-signed webhooks, skipping re-embedding when an item's text hash is unchanged, with an hourly reconcile and a daily orphan sweep as backstops.
- Moved Facebook and Instagram scraping onto users' devices (Electron over CDP, hidden mobile WebViews replaying the platform's own GraphQL) so no session is replayed from two IPs; LinkedIn and WhatsApp run server-side behind per-user geo-matched proxies with an API-contract canary.
- Shipped a live call copilot (one Deepgram stream per audio source, LangGraph), a crash-recoverable LiveKit note-taker, and turned OpenClaw into a multi-tenant agent service: 265 tools, 57 integrations, 36 OAuth providers, a 40-tool MCP server.
