Systems I've built and run

Real, production systems — not a logo wall. Commercial and leadership experience lives on the Experience page.

Featured case

AI Sales Agent

A production, serverless WhatsApp SDR agent — a deterministic guardrail mesh at its core, not an LLM wrapper.

Problem
Manual research, qualification, personalized outreach and follow-up don't scale on WhatsApp — and generic automation produces activity, not pipeline.
Built
An inbound + outbound agent on Cloudflare Workers: multi-model routing, a guardrail mesh, Whisper voice, Calendly booking, RAG over a playbook and a React operator console — human-in-the-loop on the contract.
Result
84 partner contracts and 11,925 messages in a 31-day production run; 25.1% reply rate.

Clay Enrichment & Lead Scoring

A waterfall enrichment and scoring pipeline with AI personalization over live prospects.

Problem
Single-provider enrichment leaves gaps and generic messaging; the pipeline needed a high match rate at controlled per-record cost.
Built
A waterfall over multiple data providers with fallback logic to maximize match rate while controlling cost, feeding an AI-generated personalization column from firmographic and signal data.
Result
200+ live prospects enriched and scored with per-prospect messaging.
