From operator to automation architect

After spending millions on Meta ads and building 7-figure funnels, I discovered the real leverage: custom software beats any marketing strategy.

I've been on both sides—managing €100k+ daily ad spend, optimizing conversion rates, building retention strategies. But the biggest wins came from automation: WhatsApp flows that doubled retention, time tracking systems that saved 15 hours weekly, custom Shopify apps that scaled operations.

Today I work as a technical co-founder as a service. I identify the bottlenecks holding your growth back, then build custom solutions that multiply your team's output. Every system I build pays for itself in 3-6 months.
