I audit and build automated lead and revenue engines for B2B sales and marketing teams.

• Diagnose leaks in inbound, outbound, CRM, and RevOps workflows
• Save 15+ hours/week per rep by automating prospecting, enrichment, routing, and follow‑up
• Eliminate lost leads with bulletproof error handling, retries, and dead‑letter queues
• Stack: n8n, Make, Gemini/OpenAI, AI Agents, REST APIs, webhooks, and defensive data engineering.

• What it does: Ingests vendor invoices across Gmail and webhooks, runs autonomous line-item math checks, traps billing discrepancies, blocks duplicate payouts, and posts clean invoices to QuickBooks Online with Slack human-in-the-loop exception control.
• Architecture: Gmail/Webhook trigger → Multi-format document parser → Dual AI model fallback (Gemini/OpenAI) → Automated math verification gate → Supabase zero-data-loss exception vault → Slack interactive approval card → QuickBooks Online ERP sync.
• Outcome: Reclaims 10+ hours/week of manual bookkeeping, prevents duplicate/fraudulent disbursements, and ensures 100% audit readiness with immutable failure tracking.

• What it does: Sanitizes inbound leads, filters bots, scores intent, syncs to HubSpot, and routes to Slack/WhatsApp.
• Architecture: Sub‑5s E.164 phone normalization, bot filtering, Gemini AI intent scoring, HubSpot sync, dynamic Slack/WhatsApp routing.
• Outcome: 100% invalid CRM entries blocked; response SLA from hours → sub‑5 seconds.
• 🎬 Watch 4‑min Loom Demo

• What it does: Real‑time triage of inbound leads by budget, company size, and urgency.
• Architecture: Google Gemini AI scoring + priority routing to reps/channels.
• Outcome: Saves 15+ hours/week of manual qualification; high‑value prospects routed instantly.
• 🎬 Watch 3‑min Loom Demo

• What it does: Ingests webhook leads, normalizes schema, syncs to Google Sheets CRM, and fires instant Slack alerts.
• Architecture: Webhook ingestion → schema normalization → Sheets sync → Slack notifications.
• Outcome: Lead contact time −95% (5‑minute Speed‑to‑Lead); connection rates up to +391%.
• 🎬 Watch 4‑min Loom Demo

• What it does: End‑to‑end outbound: scraping → AI copy → HITL approval → send → logging.
• Architecture: Apify scraping, Gemini email copy, Slack Human‑in‑the‑Loop (HITL) approvals, fault‑tolerant logging.
• Outcome: Reclaims ~70% of rep prospecting time; protects domain deliverability with HITL gates.
• 🎬 Watch 4‑min Loom Demo

• What it does: Finds high‑intent job leads, validates pages, extracts tokens, drafts outreach, and sends via HITL.
• Architecture: SerpAPI ingestion, pre‑flight 404/duplicate checks, JS RegEx HTML token optimization (~70% cost reduction), Gemini + Groq failover, Zod schema validation, DLQ, Telegram HITL 1‑click approvals.
• Outcome: Automates 10+ hours/week of manual sourcing/audits; zero CRM data corruption via strict schema gates.
• 🎬 Watch 4‑min Loom Demo

• What it does: Recovers lost revenue (e.g., abandoned cart/checkout) with smart, non‑spammy email sequences.
• Architecture: Make.com scenario, webhook ingestion, stateful delay gates, Supabase purchase evaluation, Gemini AI email copy, custom Gmail dispatch.
• Outcome: No redundant outreach to converted buyers; protects sender reputation; recovers lost revenue automatically.
• 🎬 Watch 3‑min Loom Demo

• What it does: Captures n8n execution failures, logs audit trails, and sends instant alerts with 1‑click debug links.
• Architecture: Centralized error handler, Google Sheets audit logs, Gmail/Slack alerts, execution debug links.
• Outcome: Prevents silent downtime; cuts triage time from hours → under 2 minutes per incident.

• Discovery: map GTM process, tools, and data flows.
• Data model: define schemas, identity keys, and quality rules.
• MVP workflow: ship a minimal end‑to‑end automation in 1–2 weeks.
• Production hardening: add retries, monitoring, docs, and handover.
• Iterate: expand to more use cases (onboarding, CS, attribution, etc.).

Open to B2B contract and fractional GTM Engineer engagements.

• Location: Zamboanga Sibugay, Philippines (PHT, UTC+8)
• Overlap: Comfortable with 8 PM–12 AM PST (9 AM–1 PM PHT next day) for standups/handoffs
• Contractor-ready: invoice via Wise / Payoneer / Deel
• Engagement model: 2-week pilot → monthly retainer
• Production standards: centralized error handling, retries, DLQ, audit logs, Loom demos for every workflow
