What I'm looking for

If you're scaling an outbound engine, I’m looking for a role where I can architect, automate, and execute GTM operations from day one.

At Interfell, I co-architected and independently maintain the Clay and n8n automation layer for multi-country lead sourcing and enrichment. I also engineered a Claude 3.5 and MCP prospecting agent that connects HubSpot with enrichment sources to search, qualify, deduplicate, and contact leads on scheduled runs.

I manage cold email infrastructure, including domain warm-up, DNS authentication, deliverability monitoring, and message testing. I also run inbound follow-up and manual prospecting, and design technical training on Clay, Apollo, Smartlead, and Claude AI for SDR teams.

On a contract through Upwork, I built a B2B database covering 540 companies and 798 verified decision-makers in regulated industrial sectors, and conducted market research across APAC, LATAM, and Europe. Earlier, at Keep Typinh CA, I handled inbound calls for high-ticket cosmetic surgery leads and achieved an 80% conversion rate on qualified leads.
