About Samuel

I structure and automate the revenue operations of SMEs and B2B scale-ups: clean CRM, reliable data, self-running processes.

🔧 HubSpot from A to Z: Architecture from scratch or redesign: complex pipelines, rights management, advanced workflows (lead routing, automatic assignment, sequences). 4 years of HubSpot & Salesforce administration in a hyper-growth scale-up, then for my agency's clients.

🧹 Data Health: Deduplication, multi-level sirenization, CRM input safeguards (Regex, real-time API validation): your dashboards finally tell the truth.

⚙️ Automation & Integrations: n8n, Zapier, Make, Python, SQL (PostgreSQL, MySQL), business API orchestration. If a task is repetitive, I make it disappear.

📊 Reporting: End-to-end dashboards (deliverability, Lead-to-Opp conversion, generated revenue) for accurate data-driven decision-making.

🤝 Adoption: Sales training, Salesbooks, tutorials, day-to-day support: I bridge the gap between technical and the field.

Some results:
- Redesign of a fintech scale-up's acquisition: 100% intent-based targeting, major improvement in Lead-to-Opportunity conversion

- CRM cleaning systems (sirenization + massive deduplication) deployed on large-scale databases

- Cold email infrastructures with an inbox rate > 90%

- End-to-end B2B SaaS delivered (Python, PostgreSQL, Docker, n8n)

My advantage: I was a salesperson before being in Ops. I know what a Salesperson expects from a CRM and I design processes that teams actually adopt. Thanks to my Growth background, I can also connect acquisition (data enrichment, outbound, scraping) to your operations.

My method: hypothesis → POC on a sample → validation → industrialization. No overly complex systems, quick wins first.
