About Dennis Simon

I build business systems that are actually used in everyday life.

Custom apps, internal tools, automations, and API integrations to help teams work faster and eliminate manual work.

​​​​​​​​​​​​ ​​​​​​​​​​​​• Automate recurring processes
​​​​​​​​​​​​• Connect different systems via APIs
​​​​​​​​​​​​• Develop internal applications and MVPs
​​​​​​​​​​​​• Consolidate data from multiple tools in one place

How I work:

​​​​​​​​​​​​ ​​​​​​​​​​​​• We define the scope together in advance
​​​​​​​​​​​​• I develop quickly, with structure, and focused on results
​​​​​​​​​​​​• Revision rounds are clearly limited
​​​​​​​​​​​​• In the end, there is something that works in practice

Why clients come to me:

​​​​​​​​​​​​ ​​​​​​​​​​​​• Processes have grown over years and no longer fit together
​​​​​​​​​​​​• Data is scattered across five different tools
​​​​​​​​​​​​• Employees manually copy what could already be automated
​​​​​​​​​​​​• An MVP, internal tool, or workflow system is needed – preferably yesterday 😄


You get a system that runs reliably, is easy to use, and remains stable even when changes occur.

👉 You know what you need? I'll build it.
👉 Not quite clear yet? I'll help you figure it out first, then build it.
