About

Two people, two countries, one standard.

We met as developer and client. Marek hired Joe to build ChartSentinel, the work went well, and we decided to do it for other people too. Joe leads engineering from Nairobi. Marek runs the business side from the Czech Republic.

Marek runs the business side of the studio and works with each client directly. He gets to know your story, your goals and how your business really works, so the project is built around what you actually need.

Why I build

I started writing software because I wanted to build things people actually use. For the past two years that has meant real products with real users: the EZCare apps on iOS, Android and the web, and the ChartSentinel trading platform.

I like owning a project from the first sketch to the release, and I like staying around after it ships. You get someone who understands the whole system, from the database to the last animation on the screen, and who will tell you plainly what is working and what isn't.
