About Me

Consulting like a true partner

I’m not a typical freelancer. I step in where things need to move fast, where clarity is missing, or where fires need to be put out. Always with high standards, hands-on execution, and a strong strategic foundation. Fast, focused, and built to get things done.

As a Senior Consultant, I take ownership of:

Strategy and decision-making frameworks
Clean, scalable marketing and CRM setups
Reliable data and meaningful analytics
Structured handover to internal teams

The goal is always the same: make marketing measurable, performance-driven, and truly manageable.

Strategic & Hands-on

I operate like an external CMO: analyzing your current situation and goals, developing a tailored marketing strategy, and actively driving execution. A strategic sparring partner that is hands-on when it matters.

CRM / HubSpot

I help with clean HubSpot setups and structured CRM cleanups. I also optimize existing CRM structures and processes - including email marketing, workflows, and overall data quality.

Data & Analysis

I support data cleanup and enrichment to ensure your foundation is accurate and reliable. I also turn complex analyses into clear, actionable insights that guide smarter marketing and business decisions.

Performance Marketing

Strong focus on data-driven lead generation through Google Ads and LinkedIn Ads. Additional I optimize channels such as Meta and YouTube to scale reach and performance strategically.
