GTM Engineer | B2B Outbound Automation | Clay - Cold Email - Lead Gen

Hello! I'm a GTM Engineer and B2B Outbound Automation Specialist with 3+ years of hands-on experience building full-stack outbound systems — from raw data sourcing through to booked meetings. My work sits at the intersection of data enrichment, AI-driven personalization, and multi-channel outreach automation. I don't just set up tools — I architect the entire outbound engine: ICP list building, Clay enrichment workflows, email and LinkedIn sequences, CRM integration, and conditional logic that makes the whole system run without manual intervention. 💥 What Sets Me Apart? Clay depth: I build multi-step enrichment pipelines, AI personalization logic, lead scoring, and webhook-triggered workflows inside Clay — not just basic tables. Clients specifically seek me out for Clay work. Multi-source prospecting: I combine commercial databases (Apollo, LinkedIn Sales Navigator) with custom scraping of niche directories, event attendee lists, and industry-specific sources using Apify and Octoparse — so your list isn't the same one your competitors are using. Full outbound stack: I work across the entire GTM toolchain — Clay, HubSpot, Instantly, Smartlead, Lemlist, Woodpecker, LaGrowthMachine, Expandi, Make, Zapier, Kixie, LeadMagic, and more. Whatever your stack looks like, I can plug in and build. AI-powered workflows: I engineer prompt logic inside Clay for context-aware personalization at scale, and I'm actively developing custom automation scripts with Claude Code for use cases that go beyond native tool capabilities. 💥 What I Build: Clay enrichment and automation workflows Cold email infrastructure and sequences (setup, copy, deliverability) LinkedIn outreach automation and multi-channel sequences Lead sourcing systems — databases + custom scraping for niche audiences HubSpot CRM integration and workflow automation End-to-end outbound stack setup for teams going from zero to pipeline Some campaigns I've run achieve open rates above 70% and reply rates of 20–34%, with positive reply rates reaching 65–77%.
