GTM Engineer · I build GTM infra for B2B SaaS [$1–5M ARR] · Claude Code · n8n · Python · Clay · Growth & technical partner. Fully hands-on.
I build the systems that take companies from founder-led to system-led. I do Growth / GTM Engineering for B2B SaaS companies doing $1M–$5M ARR. Most founders at this stage hit the same wall: Revenue is flowing. Customers are happy. But behind the curtain: → Pipeline is inconsistent → CRM data is unreliable → More tools, same confusion That's not a lead problem. It's a systems problem. I call it the Process-Market Fit gap, and it's exactly where I work. 🟩 Three things I build: → GTM stack + AI transformation: wire AI into your live GTM infrastructure. The companies doing this now compound hard. → Signal-based outbound system: buying signals → enriched contacts → automated sequences. End to end. → CRM as a revenue OS: clean, reliable data the whole revenue motion runs on. 🟩 What I bring: → Grew a bootstrapped B2B SaaS from €1M to €2.5M ARR as Head of Growth → Ran a Google-recognized performance agency out of Buenos Aires → Built acquisition, CRM, sales ops, and GTM infrastructure hands-on If you're ready to scale, let's talk. PS: 📩 I also write a newsletter for SaaS founders and operators at the same inflection point. 1,500+ subscribers. Real case studies and workflows to take you to $10M+ ARR

Cultural Fit Analysis
The candidate's career trajectory shows a strong inclination towards growth, entrepreneurship, and B2B SaaS. The diverse roles, from agency owner to co-founder and head of growth, suggest a versatile individual who thrives in dynamic environments. However, the target role is 'Frontend Developer,' which is a significant pivot from the candidate's documented experience. This creates a substantial misalignment in cultural fit for a technical development role, despite strong business acumen.
Soft Skills & Operational Fit
The candidate's experience as a Growth & Revenue Operator, Head of Growth, and CMO suggests strong leadership, strategic thinking, and execution capabilities. The descriptions imply a results-oriented individual who is hands-on and capable of building teams and systems. The 'Intelligence Officer' role, while classified, hints at analytical and problem-solving skills. The entrepreneurial background indicates self-motivation and adaptability.
