Well-Ironed: A Software Development Practice

About us

 

We are passionate about quality and the practice of software development craftsmanship.

We care a lot about correctness and the testing methodologies necessary to attain it.

We dislike overengineering and we fight nonessential complexity. We believe that less is more.

We avoid jumping on the latest bandwagon, and look for ways to achieve our goals with frugal and simple means.

We want to use this space to share our reflections and ideas about how to build better software and better environments for the people who write programs, and for the people who use them.

If you have a software project that you’d like assistance with, don’t hesitate to get in touch!

Simon Zelazny

Simon has been enthusiastic about computers since his first 486 PC, and returned to programming after a detour through Japanese Studies and language education.

Simon has worked with multiple companies world-wide, implementing effective solutions to business problems, and resilient solutions to computer problems. He’s most proud of those projects where his team was able to strike a balance between high quality and speed of delivery.

Rafal Studnicki

Rafal is a software engineer with 10 years of experience in C, Erlang, and Elixir. He has worked on various distributed systems, ranging from tiny clusters on microcontrollers to some of the largest chat servers in the world.

Having consulted on many real-world projects, he has come to believe that clean architecture, ruthless simplicity, and a principled stance towards testing for correctness are required for software to serve its business purpose successfully in the long run.
