The person behind AISuccessful
Dennis Pfeifer
Founder of AISuccessful. System Engineer, Cloud Engineer and IT Consultant with over 15 years of experience.
My IT journey started early -- at age 12, I began trying everything I could get my hands on. Curiosity turned into first projects: websites, small server infrastructures, file servers and Windows domains for local businesses.
After graduating with a focus on computer science, I deliberately chose the practical route: training as an IT specialist for system integration. This was followed by five intensive years as a System Engineer and Cloud Engineer -- building infrastructures, leading teams, executing cloud migrations.
Today I hold a senior IT position at Vizona GmbH while building AISuccessful in parallel. My focus: microservices for mid-market businesses and automating manual tasks across industries.
I work full-stack -- in every sense: Windows, Linux, AWS, Azure, containers, networks, software development, consulting, management. This breadth helps me develop solutions that actually work.

Frequently Asked Questions
Answers to the most common questions about me and how I work.
Where is AISuccessful based?
In Weil am Rhein, in the border triangle of Germany, Switzerland and France, just outside Basel. Clients across the DACH region (Germany, Austria, Switzerland) are served remotely or on site, depending on the project.
Do you work alone or with a team?
I work as a solo consultant and bring in specialized freelancers as needed. This keeps overhead low and communication direct. For larger projects, I assemble a tailored team.
Which industries do you serve?
Primarily mid-market businesses in the DACH region — across industries. Past projects span retail, logistics, manufacturing, and services. The methods and technologies are industry-agnostic.
How do you differ from large IT service providers?
Speed and direct contact. No project management overhead, no long approval chains. You always speak directly with the developer. Projects start within days, not months.
