Biography
Head of software development (CTO) with a Bachelor of Software Engineering in Web development from Higher School of Economics and almost 7 years of commercial projects development experience.
The main achievements of the company in 2018, to which I made a significant contribution:
- The company's revenue increased by 2 times per year without increasing costs due to system upgrades and optimization of the company's business processes;
- implementation of microservice architecture (instead of monolithic architecture) with the required level of fault tolerance was completed. The number of microservices at the time was 48;
- the use of computer vision services in the production environment began to reduce the company's costs of extracting useful information from photos of retail chains' prices (the company receives approximately 1.5TB of new photos in jpeg format per month).
I'm experienced in Unix systems and web development using modern technical tools like Golang (use it in production from 2015), gRPC, Consul, Docker, Angular 2+, PostgreSQL, Redis, WebSocket, Ruby on Rails, Pandas for data data engineering, Slack and other useful things for development.
Able to setup and maintain production servers from scratch with all necessary services like SSL connections, mail server with DKIM, monitoring and profiling systems.
I like to design and implement API modules. Prefer microservices infrastructure for big commercial projects. Using SCRUM and TDD development approaches while working with team.
