ABOUT ME

Diogo Lean Veiga

UX & Product Designer • AI Automation Specialist • Growth & Performance Marketer
Master’s in Human–Computer Interaction (ESDI/UERJ — Admitted 1st Place)

I’m a multidisciplinary designer and growth engineer with over 15 years of experience building digital experiences, high-performance automated systems, and scalable acquisition funnels for global audiences. My work directly bridges the gap between clean UX, advanced technology, and real business results.

By combining design thinking with programming and performance marketing, I design and run complete digital ecosystems—from initial user research to active paid traffic campaigns and conversion optimization.

Who I Am

I combine academic depth with highly practical, real-world execution. I hold a Master’s in Human–Computer Interaction from ESDI/UERJ (where I was admitted in 1st place), one of Brazil’s most prestigious design institutions. My career is defined by building high-impact assets:

  • Performance Marketing & Paid Media: Hands-on experience structuring, launching, and scaling Meta Ads and Google Ads campaigns focused on direct-response ROI and high-margin product sales.
  • Data-Driven Optimization: Specialist in tracking and analyzing key metrics (CAC, LTV, conversion rates, and ROAS) to continuously refine funnels and drop acquisition costs.
  • AI-Driven Automation: Developer of custom backend integrations and automated audience communication systems that scale marketing operations with zero overhead.
  • Audience Scaling: Creator and operator of massive international social media networks with over 700k active followers.

What I Do

I build and optimize the entire path a customer takes—from the first ad impression to the final checkout confirmation.

How I Work

I believe design is only successful if it drives action. Every button, layout structure, or email sequence I build starts with clear business objectives and user clarity. My goal is always to create highly efficient, beautifully designed digital systems that run on autopilot, convert consistently, and scale predictably.
