Software development for specific requirements

I support companies with the development of new software, existing applications and technical work that requires additional experience or development capacity.

01

Custom software development

When standard solutions do not fit the actual workflows, I develop software for the specific requirement.

What I can take on

  • Custom features and applications
  • Internal software for existing business processes
  • Extensions to existing applications
  • Integration of existing systems and data sources

Who this is for

Companies with their own workflows or requirements that cannot be handled effectively with standard software.

Typical situations

  • A manual process needs to be replaced by a custom application
  • Existing software needs additional functionality
  • Several existing systems need to be connected technically
02

Backend & API development

I develop and extend backends, APIs and interfaces for web applications, digital products and existing software systems.

What I can take on

  • Backend development
  • REST APIs
  • Interfaces between systems
  • Integration of external services
  • Database integration and data processing

Who this is for

SaaS providers, product teams and companies that need a stable backend or reliable technical integration between systems.

Typical situations

  • A frontend needs a new backend or API
  • An existing product needs to be extended with external services
  • Data needs to be exchanged between several applications
03

Modernisation of existing software

Software grows over the years. Structures become more complex, technical dependencies age and changes become increasingly difficult. I help companies continue developing these systems in a controlled way.

What I can take on

  • Analysis of existing applications
  • Technical development of existing systems
  • Replacement of outdated structures
  • Step-by-step modernisation
  • Resolution of technical problems

Who this is for

Companies with production software that needs to remain in use but is becoming increasingly difficult to maintain.

Typical situations

  • An older application needs further development
  • Changes have become unnecessarily difficult because of established structures
  • Parts of an existing system need gradual modernisation
04

Technical consulting & development support

I support existing development teams and companies with technical tasks, decisions and ongoing software projects.

What I can take on

  • Temporary support for existing development teams
  • Analysis of technical problems
  • Support with technical decisions
  • Implementation of specific development tasks
  • Continued development of ongoing projects

Who this is for

Companies, agencies and development teams that need additional senior-level experience for a limited period.

Typical situations

  • The team temporarily lacks development capacity
  • An existing project needs additional backend experience
  • External support is needed for a technical problem
05

Automation & process digitalisation

Recurring manual work costs time and quickly leads to unnecessary errors. I develop technical solutions that simplify or automate these workflows.

What I can take on

  • Analysis of existing manual workflows
  • Automation of recurring processes
  • Data exchange between existing systems
  • Interfaces and integrations
  • Custom software for internal processes

Who this is for

Companies where data is regularly transferred, tasks are repeated or workflows are handled manually across different systems.

Typical situations

  • Data is regularly transferred manually between systems
  • Recurring tasks should run automatically
  • An internal manual process needs to be digitalised
06

Websites & web solutions

I develop professional websites and custom web solutions for companies that need a modern and technically solid online presence.

What I can take on

  • Professional company websites
  • Single-page and multi-page websites
  • Custom web solutions
  • Responsive implementation for mobile, tablet and desktop
  • Technical setup and operation

Who this is for

Companies and self-employed professionals that need a new website or want to replace their existing online presence.

Typical situations

  • A company needs its first professional website
  • An existing website is technically or visually outdated
  • A website needs custom functionality or structures
