Konstantin Riabinin

I combine three profiles that rarely coexist: a founder-CTO who took a company from its first engineers through a successful exit, an organization builder who has stood up engineering orgs of up to ~100 people from scratch, and a hands-on technical leader who still personally ships production systems. I have built organizations from the ground up three times: Zvooq (to 60 as CTO), a Sberbank department (to ~100), and Altium's Serbia site (now 75+).
