I am a result-oriented full-stack software developer. I have got three years of experience in commercial development. I have worked on the implementation of a highly configurable web-based application without a single point of failure. Designed and wrote microservices in Java, Golang programming languages. Using GCP, AWS, and other computing cloud platforms to deliver solutions. Implemented an information security framework that states that organizations should not trust any entity inside or outside of their perimeter at any time. It provides the visibility, and IT controls needed to secure, manage, and monitor every device, user, app, and network being used to access business data. It also involves on-device detection and remediation of threats. I have developed a platform for the efficient processing of massive data in real-time. Reduced processing time of web requests and SQL queries applying a cache.
Contribute to open-source projects like Ignite, Spring, Kubernetes.
I like flexible working hours, but dislike idle talk and useless meetings that steal our time. I have claims to micromanagement and hate hypocrisy and falsehood.

Designed and led the development of such projects: - trading binary options platform - investment social network with wide financial statistics. The general key features of the investment social network (without common) were: - It was able to connect to several trading platforms at once and give the user full trading statistics on his accounts - Some customers had the opportunity to invest in the accounts of other customers and receive a share of the profit from the accounts in which they invested. I led a small development team consisting of no more than three developers. Both projects were designed according to the principle of microservice architecture. In projects, containerization (Docker) of components was actively adopted. Apache Kafka was used in the social network project. It made easier to implement component scaling and balance traffic between them. To collect, store financial raw data, and obtain aggregated results, the clickhouse column database was used. It made easier to collect data and reduce the amount of data stored. Some services were written in Golang, some in Python, there was also a piece of legacy code written in PHP. Until DevOps engineer joined the team my duties included also installing and configuring workflows - gitlab, youtrack, Jenkins, chat.

Интеграция нового поставщика в систему бронирования отелей за три дня (импорт/экспорт, поиск, заказ, отмена и т п), когда клиент ждал минимум за 21. Мы поспорили и выиграли 18000 фунтов (по 1000 за каждый день, оставшийся до 21). Если бы сделали за 21+ день - проиграли бы по 1000 за каждый день задержки.
Интересные задачи. Возможность удаленной работы.
