Experience
Taxi Business Automation
I started as a C# full-stack developer for the back end and desktop to automate a taxi call center. It later expanded to automation of all departments of the taxi business, including client and driver mobile applications on Android and iOS. Besides desktop, back end, and mobile, there were a lot of web services as well.
My position evolved to the CTO level, and I was responsible for everything related to engineering, infrastructure, and support.

DefinedCrowd Platform
I led the engineering and DevOps team in creating the data sales marketplace aimed at data scientists and creating the whole infrastructure from scratch. We built the MVP and hosted our first clients in three months.
Besides contributing to the DefinedCrowd platform, I worked on almost all projects as a quality engineering architect. It was the highest QA position in the company, so I defined the vision, processes, and architecture and implemented frameworks and libraries. I also communicated daily with more than 12 teams, cluster managers, and the CTO.

Xapo Bank
I recreated from scratch a quality function in the first crypto bank that offered both US dollars and Bitcoin. I also designed a new vision where quality is owned by developers and implemented it for 1.5 years.
We went from a mindset of developers throwing over-the-wall builds to QAs to not having any QA in the teams and removing the quality department. While ensuring a high-quality level and faster delivery by utilizing a shift left and right in quality, an almost excessive amount of test automation, proper processes, CI/CD, a huge focus on observability, a lot of pairing, and various DevOps techniques.
Without forgetting about DevOps, SRE, and platform teams, we also defined the strategy and built solutions for them to ensure the quality of the infrastructure.
