Turning ideas into digital solutions with strategy, code and business vision

I'm Claus Haas — full-stack developer, cloud infrastructure and automation specialist. For over 12 years, I help companies break the barrier between having technology and using it with strategic intelligence.

My main motivation is simple and powerful: seeing things work as they were envisioned. While many get frustrated trying to turn ideas into viable systems, I step in to translate vision into structure, eliminate bottlenecks and accelerate growth.

More than writing code, my job is to understand the heart of your business and turn it into efficient systems, intuitive interfaces and automated flows that really make a difference. Every line of code has purpose. Every automation has impact. Every system I build delivers what every company seeks: efficiency, control and real scalability.

What I do in practice:

  • I develop robust applications with React, Node.js and AWS.
  • I integrate CRMs like Mautic, Infusionsoft, RD Station and HubSpot with automations that save time and increase conversion.
  • I automate sales, support and email journeys, eliminating manual tasks.
  • I connect disparate tools and deliver platforms that work — in practice, not just in theory.
  • I design scalable architectures focused on performance and sustainable growth.

Proven experience

I have led the development of platforms with over 70,000 active users, integrating payment systems, CRM, email marketing and notifications in an efficient digital ecosystem. I have worked with tools like React, Supabase, WordPress, Mautic, Infusionsoft, TypeScript, React Router, AWS and others — always focused on the strategy behind the technology.

When do they look for me?

  • When it's necessary to integrate systems that don't talk to each other.
  • When manual processes are blocking operations.
  • When data needs to become decisions — not spreadsheets.
  • When it's time to deliver with precision, clarity and performance.

What drives me:

  • Create applications that sell, scale and delight.
  • Automate what slows down, connect what's loose and bring data to life.
  • Make technology work for the business — not the other way around.

The right technology, in the right place, changes everything.

If your operation still depends on improvisation and manual processes, maybe what's missing isn't effort — but the right structure, designed the right way. My role is to build that structure. And make your company breathe easy.

No matter the size of your idea, it deserves to become reality. With strategy, efficiency and real technology.
