About me:

• My strong side is a vast experience. I worked for leading companies across the world: Revolut, William Hill, Leo Burnett, Ogilvy, etc. Worked in product and R&D teams, and did things not many developers tried: Web UI applications, WebGL shaders powered games, sound editor in JavaScript, you name it.
• I am one of the early adopters of React, tried Angular, Svelte and Vue for smaller projects but wouldn't say I am a fan of any technology, for me, they are just a tool you have to know to achieve a result.
• Even though I strongly prefer colocated teams I have experience of work with remote, huge, and highly distributed teams. I'm not a certified Scrum master, but I'm a strong scrum believer if it is done right.
