I took great care to prepare my successor at EX.CORP to take over my duties, sharing my experience and insights and providing ample support to ensure a smooth transition.Consulted multiple other companies:- Got to actual problems in less than 30 minutes | https://xyproblem.info/- Proposed solutions that were implemented / followed

Started as a consultant but became the full-time CTO in just two months to conduct the search for a new CTO.The company had grown to thousands of employees; however, the Tech department continued to operate like a small outsourcing company it once was. I restructured the department and improved its interactions with the rest of the company.Results: built a strong leadership team, transformed technology-oriented teams into cross-functional ones, implemented a business-transparent planning process, organized and simplified budget management. Technical accomplishments: reduced database load, isolated internal infrastructure & services from the internet, initiated migration from GitHub to self-hosted GitLab. Eliminated idleness & toxicity through significant reorganization, while replacing only 1/5 of the existing team.

- Transformed an overburdened couple of operations engineers into a happy, self-sufficient, and growing team, Platform Team.- Defined a vision for the platform and created a migration plan for all the development teams- Established effective communication channels and practices- Transitioned from weekly night meetings to figure out why production is down into rare incidents- Defined infrastructure as Code using Pulumi- Clarified & unified deployment (GitLab CI + Pulumi) and monitoring practices

Taught two courses to 4th-year students at Institute of Computer Science & Technologies.Computer Network Technologies.This course focuses on developing software that reliably works with modern networks.- Created and conducted a course of laboratory work- Wrote and taught a companion course of lectures- Developed Infrastructure as Code solution to spin up lab stands for students in Digital Ocean & LinodeSoftware Development Engineering.This course is dedicated to the processes, workflows, methodologies, tooling, and other aspects surrounding the code-writing part of developer's life.- Co-authored the course of lectures- Taught it in a dialog podcast manner
