Summary

As an experienced startup CTO, tech lead, software architect, and senior backend software engineer, I am passionate about building new projects and leading high-performing teams. Currently, I am seeking a position as a Chief Technology Officer (CTO) or Director of Software Engineering in a fast-growing small to medium-sized company. My ideal goal would be to build and manage a remote or hybrid team of teams (15-40 people in total) in Europe, possibly by establishing a development or R&D Center for a Western European or American company. In my recent role, I led a team of 10+ people to develop a web platform for recruiting experts, which included AI algorithms for faster matching candidates with projects. I am well-versed in the latest technologies and thrive on working with talented individuals who share my commitment to continuous improvement. I am also eager to mentor team members and help them reach their full potential. With my extensive background in algorithms and data structures, as well as my experience building products from scratch, I possess a unique combination of skills that enable me to navigate complex technical challenges while also understanding the business aspects of projects. Having worked remotely since 2016, I'm comfortable and effective in a distributed team environment. If you are looking for a seasoned technology professional with a passion for building innovative solutions and leading high-performing teams, I am eager to connect with you. #OpenToWork #softwareengineering #technology #startup #directorofengineering #CTO #chieftechnologyofficer #startupcoach Top skills: Software Engineering Practices, Jira, Team Management
