Guilherme Luiz B.

I'm a Revenue Operations specialist who builds the systems that decide which leads get worked and turns messy CRMs into engines leadership can trust. Top Rated, 100% Job Success, HubSpot RevOps certified. Recent work: ⚙️ LEAD SCORING & FUNNEL DESIGN — For a US real-estate marketplace, rebuilt the lender lead funnel end to end: scoring model across ~65,000 contacts (backtested against 22,671 deals — cut disqualified-lead leakage from 32% to 13% while keeping 52% of winners), MQL gate that produced 1,700+ qualified leads in 24 hours at launch, and a lifecycle engine classifying ~46,000 contacts. 📈 FORECASTING & REVENUE MODELING — Built the forecast model behind that funnel: upside/base/downside scenarios on live close-pace and deal-velocity data, every input tagged live vs. derived vs. assumed, reproducible in code — presented to Sales Leadership, sizing the funnel's contribution at $1.4–2.2M in-year. Separately restored forecastability of ~€4M in stalled pipeline for a consulting client and shipped the dashboard on top of it. 🔍 CRM AUDIT & REMEDIATION — For a Danish clinical-research company (5.0★ on Upwork): audited 41 HubSpot workflows, 13 Make scenarios and 30 email lists; found and fixed a GDPR consent exposure affecting ~4,300 contacts; restored a broken lifecycle model with line-by-line reconciliation; made €4M of pipeline forecastable again. The client's words: "Guilherme is the complete package." 🤖 AI-NATIVE AUTOMATION — I ship AI inside revenue systems, not just talk about it: LLM call-transcript classification running in production HubSpot workflows, AI lead summaries routed to Slack, and a custom HubSpot MCP server (TypeScript) that lets AI agents operate a CRM with guardrails. 📊 DASHBOARDS & DATA — SQL/Supabase data mirrors, 11 executive dashboards (React/Next), attribution foundations, deliverability forensics. How I work: audits before opinions, backtests before thresholds, dry-runs before writes, rollback plans before launches — and honest numbers (I'll always tell you what's measured vs. modeled). Stack: HubSpot (RevOps + Marketing Hub certified) · ActiveCampaign · n8n · Make · Zapier · SQL/Supabase · Python · Claude/GPT production workflows. If your CRM has leads falling through cracks, scores nobody trusts, or automations nobody dares touch — that's exactly the work I do. Let's talk.
