Web application development

Internal tools, client portals and line-of-business applications built around how you actually work. You talk directly to the person who writes the application, not to a salesperson.

What I build

Applications for processes currently held together by spreadsheets, email threads and conversation.

  • internal record and warehouse systems
  • client portals with their own logins
  • quoting and invoicing tools
  • dashboards for jobs and capacity
  • a CRM shaped around one operation
  • connections between existing systems

How a project runs

We start with one process and a usable version, not an eighty-page specification.

  • a conversation about the actual process
  • proposal with scope and price
  • first usable version in weeks
  • tested on real data in the business
  • adjusted after real use
  • handover with documentation

When it pays off

Custom software makes sense once a standard product adds more work than it removes.

  • the spreadsheet became a database
  • several systems know the same number
  • off-the-shelf fits about eighty percent
  • every new hire needs to be trained on it
  • one process rests on one specific person

Working languages: English and Czech

I work from Czechia for clients across Europe and further out. Everything runs in English — calls, documentation and handover — or in Czech if that suits you better. Time zone is CET, which overlaps a normal working day almost everywhere in Europe and the morning in the US.

FAQ

How long until a usable first version?
For a clearly scoped process, a version your team can genuinely work with typically lands in four to eight weeks. Larger systems then grow in steps rather than arriving all at once.
Do you work alone or with a team?
Alone. That means no handing off to juniors, no project-management markup, and you always speak to the person writing the code. It also means I take on a limited number of projects at a time.
What if I need someone else later?
You get the source code, the documentation and the access. I build on mainstream technology like React, Next.js and Postgres so another developer can pick it up without starting over.
Can you take over an existing application?
Yes, where the code is accessible and the stack is common. I look at the project first and tell you honestly whether taking it over or rebuilding is cheaper.
