Aliaksei Saskevich

CTO at Sequoia | Backend Lead at Gem Space | 11+ years of Expertise



I started to dive into coding in 2008 at the school. From this moment on, I made a decision about my future profession.

In 2013, representing Homi’el, I won the Final Stage of the Republican Olympiad in Informatics and got a chance to get a high education at a leading IT university in Belarus. Shortly after starting my studies, I landed my first commercial job thanks to a hackathon that opened the door to the industry for me.

Here I worked on KUKU.io, a social media management application for small businesses and agencies, as well as GanttPRO, an online project management tool.

Since that time I gained a lot of technical and theoretical experience along with practical experience in various fields like front-end and backend, mobile development, AI, cloud and DevOps operations, team leading and building products.

At DevTeam Group, I’ve grown from a developer to a backend lead and eventually to an architect. I contribute to building Gem Space as a B2C product while also helping shape and scale CoWork, our B2B solution built on top of the same platform.

I also develop iOS applications and create my own music — two areas that let me combine engineering precision with creativity.

Now I’m taking part in Sequoia, the product meant to break the stigma about men’s health.
