Hi, I'm Jacek.

I build software that has to keep working: distributed systems and the integrations that connect a team's tools. I work with companies and with the third sector.

What brings you here?

for engineering teams

Software engineering

  • Distributed, event-driven systems
  • Integrations between systems and teams
  • Performance, cost and security

Today mostly .NET and Azure. The stack is a tool, not a limit.

third sector

Non-profit & NGO

  • Consulting: knowledge base, grants, donor journeys
  • Integrations: payments, CRM, email
  • Products for organisations

For foundations, associations and other third-sector organisations.

for business owners

Solutions for business

  • You bring the problem and know your trade, I bring the engineering
  • I look into the challenge and propose a solution, if there is one
  • Then I build it and hand it over

For companies without their own tech team.

What I stand for

Simple beats cleverThe smallest thing that solves the problem. Complexity has to earn its place.
Done means in productionI take ownership and see it through, without waiting for a ticket.
Evidence over opinionA check that runs is worth more than a claim that sounds right.
People decide, tools helpAI drafts and checks. A person approves what goes out.
Secure by defaultSecrets in a vault, least privilege, personal data only where it must be.
