At this position I am responsible for the architecture design, development, code review, and maintenance of the company's server infrastructure. As the company grows, it constantly needs to optimize software and increase the server capacity while maintaining fault tolerance, high availability and maintainability, so this is also my main responsibility. To meet all these requirements I built microservice architecture, mostly using Go, Rust for some high-load services, JavaScipt/TypeScript (Vue, React) for frontend, and some other languages for different tooling and legacy services. A lot of technologies are used, such as Nomad, NATS, Kafka, Redis/ValueKey, MySQL, MongoDB, RocksDB, Clickhouse, ML/AI (ChatGPT and others).

Responsibilities include architecture design, code review, development and publishing of a few iOS applications, as well as refactoring and migrating legacy Objective-C code to brand new Swift. With zero-tolerance to bugs, TDD and BDD principles were enforced in the department to make our applications stable and users happy.

At this position I was responsible for architecture design, core review, and development of the company's website. Perfect knowledge of PHP (Kohana, Laravel), JavaScript (Angular), MySQL, Redis, RabbitMQ were required to accomplish the company's goals.

Toonator was my pet-project which was raised from a small application for drawing animations with friends to a huge public web service with millions of page views daily. As service suddenly became viral it was important to quickly resolve issues with performance to keep visitors happy. A lot of technologies were used to make it happen and keep minimum latency at low maintenance cost: PHP, JavaScript/TypeScript, C++ as main programming languages, Memcache and Redis for caching, RabbitMQ for scheduling asynchronous tasks, MySQL and MongoDB for storing different types of data, own ffmpeg fork optimized for rendering animations.

JustScrollMe is result of HackDay hackathon event that I won with my team.In 48 hours JustScrollMe was born and grown from idea to prototype. In these two days Kirill created minimal editor for animation effects. Also landing page that available today at JustScrollMe.com was created.After the hackathon I was responsible for development of animation framework that currently used for some landing pages.
