Services

I specialise in web application backends, databases and long-term care of information systems.

Taking over and evolving existing applications

I find my way around someone else’s code, fix bugs and safely add new features.

  • review of the existing code, database and operation
  • bug fixing and stabilisation
  • gradual modernisation without rewriting everything from scratch
  • documentation, so that others can work on the project too

Custom web application development

From requirements analysis and design to deployment and ongoing support.

  • requirements analysis and technical design
  • internal information systems, portals and client zones
  • administration, records and data management
  • server deployment and operation

Databases and performance

Data model design, SQL query optimisation and faster applications.

  • data structure design – PostgreSQL, MySQL/MariaDB, MS SQL Server
  • finding and optimising slow queries and indexes
  • data migration between systems

Integrations and APIs

Connecting external systems – e-shops, warehouses, accounting and Czech data boxes.

  • REST API design and implementation
  • data bridges between e-shop, warehouse and accounting systems
  • integration with Czech data boxes (ISDS) and other services

How we work together

We choose the form of cooperation to suit the project. You always know in advance what you are paying for.

Time and materials

Suited to maintenance, fixes and smaller changes. You pay only for the hours actually worked and get an overview of what I did with each invoice.

Estimate and milestones

I split a larger project into milestones with an effort estimate. You approve each milestone up front and I invoice it once it is done.

Long-term care

For systems that run for years, we agree on a regular scope of work. The application has a dedicated developer who knows it.

I invoice as a self-employed contractor. I work remotely from Ostrava; we talk by e-mail or video call, and we can meet in person by arrangement.

Who I work for

Most often small and medium-sized companies that need a reliable developer for long-term cooperation – whether for a new application or for a system that is already running and needs someone to look after it.
