GTM Go-to-Market Engineer · RevOps

I build the systems that find,
enrich, route, and convert leads
across 5 markets.

I turn hard-to-reach leads into booked meetings. I build the enrichment, outreach automation, and AI SDR systems that sit between a raw list and revenue.

01 Data engineering

The lead engine

A multi-source enrichment pipeline that turns a raw list into a clean, reachable one that is verified, de-duplicated, and ready for outreach across every market.

The problem

We had thousands of leads but no contact details. Without a verified email or phone, there is no one to reach out to, so most of the list was unusable.

The system

Leads are enriched with verified contact details: emails and phone numbers gathered from multiple sources, including data providers, web scraping, and outbound voice agents. Everything is verified, matched, and merged into one clean list, with duplicates minimised before records reach the CRM. One pipeline serves all five markets.

02 Inbound infrastructure

Automated lead capture

Every inbound channel flows into one place, then gets cleaned, filtered, de-duplicated, and routed to the CRM in real time, so no lead is entered by hand or lost.

The problem

Inbound leads arrived across half a dozen channels with no single place to catch them. They were entered by hand, routed slowly, and sometimes lost entirely.

The system

10+ small cloud services, one per channel. Each tidies up the incoming details, filters out test submissions, adds the lead to the CRM without duplicates, and tags its source for attribution.

03 AI automation

AI SDR agents

We set the target audience and design the campaigns; the AI SDR runs the conversation the moment a lead replies. It stays playbook-grounded, runs 24/7, and keeps a human in the loop about 20% of the time.

Why speed-to-lead wins

A lead that messages at 2:14am gets a reply at 2:14am, not 9am tomorrow. Speed-to-lead is one of the strongest levers on conversion.
