Mark Sinitskiy

Tripycal.com developer and a bit more... I’m Mark, software engineer specialising in front-end development living in Krakow, Poland. My primary focus is on the React ecosystem. I appreciate A/B testing based development and analytics-driven decisions, which I believe are crucial for creating user-centric applications.

I am a fan of photography, travel, and hiking. I’m also interested in programming and food. You can visit my company website with a click on the button above.
