I build cold email infrastructure and Clay enrichment systems for B2B teams, then hand them over with training or run them for you. Recent work: a 34.5% bounce rate rebuilt to 2.0%, a 46,000-organisation database built for a sector Apollo and ZoomInfo don't cover, and 7 meetings booked in 5 days of a new launch.
I'm a British GTM engineer and owner of Groundswell GTM. On Upwork: Top Rated, 100% Job Success, five 5.0 reviews, and a longer list of clients off-platform. Clay Certified Expert.
Most teams that hire me have already bought the tools: Clay, a sequencer, a CRM. What they don't have is the system underneath: verified lists, warmed inboxes, deliverability that holds, replies landing in the CRM, someone reading the numbers. I build that part, inside the stack you already use.
If you're starting outbound from zero, I build the stack too.
WHAT I BUILD
Clay lead lists and enrichment
Company-first list building, a tight title whitelist, then waterfall enrichment and verification in Clay. For an NZ agri-tech company running a Spain pilot: 168 of 231 target companies came back with a named decision-maker (72%), 317 valid emails, none generic. Clay's own domain guess was wrong on more than a quarter of them. I check before anything touches your CRM.
Cold email infrastructure
Secondary domains, inboxes, SPF/DKIM/DMARC, 30-day warm-up, verification before anything loads, deliverability monitoring after. For a US cloud consultancy I rebuilt a 34.5% bounce rate to 2.0% and handed it over with 7 SOPs and 7 Looms.
Cold email campaigns in Smartlead
Sequences, inbox rotation, A/B tests, reply classification, bounce and deliverability checks before every send. Cold email is measured on positive replies and meetings booked, not opens. A September relaunch booked 7 meetings in its first 5 days.
LinkedIn outreach in HeyReach
Connection sequences, nurture, signal-triggered follow-up, routed alongside the cold email sequence. 43 replies from 151 conversations on one book. Website visitors routed into LinkedIn: 31 replies from 92.
Multi-channel orchestration
Clay to Smartlead to HeyReach, with replies and outcomes syncing to the CRM. One programme runs on a custom TypeScript and GitHub Actions pipeline. On another, reply-to-CRM routing creates the contact and the opportunity so the client sees their own pipeline.
CRM and RevOps
Selection, architecture, cleanup, deduplication, routing and reporting in HubSpot, Attio, Pipedrive and GoHighLevel. For a 25-person company: 10 CRMs assessed, 3 shortlisted, a 4-month implementation live on time, with training and a helpdesk inside the CRM. For a B2B services group: HubSpot and Apollo database cleaned, sync fixed, GDPR lawful-basis tracking added.
AI in the workflow
Enrichment prompts and personalisation logic inside Clay, plus custom automations built with Claude Code where the native tools stop. AI drafts the first touch. A human reads every reply.
RECENT WORK
US marketing agency serving nonprofits. Apollo and ZoomInfo barely cover the sector, so I built the database from source, with 9 custom Clay function tables: 46,051 organisations, 20,623 primary decision-makers. The newest campaign launch booked a minimum of one meeting per day in the first week.
Outbound arm of a web agency, running cold email for nine downstream clients. I audited all six inherited accounts, rebuilt the infrastructure to a 30-day warm-up standard and replaced the vendor data with a company-first Clay pipeline. The two worst accounts went from 17% bounce rate down to 0%. A recent campaign: 78% positive reply rate and 100% converted to meetings. Converted from a fixed build to a monthly retainer.
HOW I WORK
Nothing sends without human approval.
Draft, verify, then publish. I re-read what the tool did, not what it said it did.
Meetings over positive replies, positive replies over reply rate. Raw reply rate is vanity.
Documentation is a deliverable. SOPs, Looms and a runbook ship with every build.
Fixed-price milestones with a written acceptance definition. That is what has worked best on Upwork.
TWO WAYS TO ENGAGE
Build and hand over. I build inside your stack, document it, train your team, and leave. You keep the domains, the inboxes, the Clay workflows, the data.
Build and run. Same build, then I operate it: monitoring, iteration, monthly reporting.
Most clients decide near the end of the build, once they know whether someone internal will take it on.

I build n8n automations that handle real customer conversations and lead pipelines, not just app-to-app connectors, but systems with the guardrails production use actually needs
What i specifically build:
✅ AI chat automation grounded in your own knowledge base, responses are restricted to retrieved context (RAG), so the bot doesn't guess when it doesn't know
✅ Clean human handoff logic, status/label-based routing so a human agent and the bot never respond to the same conversation at once
✅ WhatsApp Cloud API integration wired directly into n8n for customer engagement and lead capture
✅ CRM/lead automation with real duplicate-prevention logic, matching by email/phone before create, branching into update-vs-create, tagged by source/campaign for routing
✅ Automated reporting pipelines (Google Sheets, email digests) that run on schedule without manual pulls
Recent work includes end-to-end lead generation systems (scraping, enrichment, AI-personalized outreach), CRM/dedup automations, and AI customer-service workflows with RAG and handoff logic
I'm upfront about what i have and haven't built before, if a stack is new to me, i'll say so and give you a realistic timeline instead of guessing
Based in Jakarta, working WIB hours. Let's talk about what's slowing your team down
