I run the outbound loop — ICP → sourcing → enrichment → verification → cold email → CRM —
and build the automation underneath it when off-the-shelf tools run out.
I am not a developer who drifted into sales. I ran outbound by hand first — sourcing, qualifying, and sending for a UK property compliance company, alone, for six months. I scraped 150 websites a day by hand and asked to automate it. The answer was no.
So the tools below are not tutorial projects. Each one removes a bottleneck I personally hit while trying to get a reply rate off the floor.
The lesson that shaped all of them: most outbound does not fail on copy or tooling. It fails on the list. I burned five months and 15,000 sends learning that.
| 50,000+ | B2B contacts sourced and processed |
| <1% → ~7% | reply rate after diagnosing a failing 15,000-email campaign |
| 1,000 → 70 | prospects qualified down; 70% replied, 25% of those bought |
| 576 leads / 49 min | two sources, deduplicated, delivered unattended |
| 22,700 → 9,567 | messy client list cleaned, deduplicated and ICP-qualified |
Full teardowns — including what broke and how it was fixed — are on the portfolio.

There is a seventh, private: an orchestration layer that runs these together — plugin system, SQLite run history, FastAPI control surface. One command returns a finished, deduplicated sheet. That one stays closed because it is the thing that turns a six-hour delivery into 49 minutes.

Salesforce appears in roughly 45% of GTM engineering postings and I have not worked in it. Listing it as a skill would be a lie you would find out about in week one, so it is listed here instead.
Open to GTM Engineer / RevOps roles and freelance outbound work. Remote, UK and US hours.
If your outbound is not working, the fastest thing I can do is tell you whether it is a list problem, a deliverability problem or a targeting problem — usually within one conversation.
