About William

Most acquisition systems fail for the same reason: they are built by technicians, not by builders who think about those who will use them. Salespeople don't adopt tools they don't understand. Complex workflows fall into disuse as soon as their creator leaves.

I build differently.
My background is unconventional: product designer at Accor on a loyalty program for several million users, then product builder in a no-code agency, and now GTM engineer specializing in B2B automation. This common thread has taught me something that few technical profiles possess: to design systems from the perspective of those who use them, not from the perspective of those who build them.

Concretely, this changes everything. A HubSpot dashboard that your Sales team reads in 10 seconds instead of 2 minutes. A documented and maintainable n8n workflow, not a black box. An outbound sequence built around the prospect's journey, not around the tool's capabilities.

Fundamentally, I focus on three areas. Building automated outbound machines: Clay enrichment, LLM scoring via Claude, n8n orchestration, Lemlist sequences by segment, HubSpot integration. Launching growth campaigns: targeting, personalization at scale, A/B testing of messaging angles. CRM & data infrastructure: HubSpot configuration, attribution workflows, data hygiene, actionable dashboards.

Recent results: +30% CRM data reliability on a B2B acquisition pipeline, 15% reduction in no-show rate through intelligent follow-up sequences, internal tool delivered in 3 weeks reducing daily admin processing time from 2 hours to 30 minutes.

I work remotely with complete documentation for each system delivered. You understand what I build, and you know how to use it without me.
