For 10 years I have been the founder and technical leader of an online-travel project. During this time we have grown from a small Russian startup to an international company in the European and American markets. I started as a backend programmer, understanding how the business works, went through the stages of Frontend-, Backend-developer, DevOps engineer, analyst, project and product manager. Now I manage a stellar team of developers, provide technical expertise for products. I organize processes not only in my department, but in other aspects of the company as well. One of the main things we do is integration of different services. I myself spent years integrating dozens of data providers from Google to BookingCom. We developed a public GraphQL API for our main product. I'm responsible for communications with our partners. I do a lot of communication with teams from different countries, write technical documentation, do analysis and development of API as a standalone product. During the pandemic, when tourism was broken, I immersed myself in product management theory to see, through the eyes of a developer, how to do successful projects the right way. This knowledge helped me restructure internal company processes and build effective team and backlog management.
