Services

What I do for you.

Four areas where I support you, in full or in parts. From independent consulting through the concept to finished software. Mobile and desktop applications come in where your product needs them.

1. 01

   Consulting & concept

   Not every undertaking needs code right away. I advise independently and technology-agnostic: as a sparring partner for upcoming decisions, with an honest second opinion, or a worked-out concept your own team can implement. From feasibility through an architecture outline to a clear recommendation.

   What you get

   • →A solid basis for your decision
   • →An actionable concept instead of vague ideas
   • →An honest assessment, even when it is inconvenient
2. 02

   Software Development

   I build and maintain web applications across their whole lifecycle. With an eye on performance, maintainability, and code the next team can still read. Native apps for iOS, macOS, and Android where needed. For larger undertakings I draw on an established network of experienced specialists, so even extensive projects ship reliably.

   What you get

   • →Applications delivered on time and on budget
   • →Maintainable code instead of growing technical debt
   • →One considered stack instead of many isolated tools
3. 03

   Architecture & Tech Leadership

   Architecture for systems with high load, many tenants, and strict security requirements. Plus technical leadership of teams, from the decision to delivery. The result: systems that grow with you instead of being rebuilt after two years.

   What you get

   • →Architecture that grows with your business
   • →Clear technical decisions instead of endless debate
   • →Teams that deliver
4. 04

   AI Consulting & Integration

   I assess honestly where AI helps your product and where it does not. When it pays off, I integrate it so it runs reliably in production and still works a year later. No gimmick, no hype.

   What you get

   • →AI that solves a real problem
   • →Clarity on what pays off and what does not
   • →An integration that survives production
