Built multiple fault-tolerant 0-maintenance systems operating 24/7/365. Still maintaining a connection with multiple devs I've mentored, sometimes they reach out for a bit of friendly advice on the development process, tech, or people challenge.
I'm looking to work on the "technological enabler" kind of products. I expect openness to changes, reasonable tech choices freedom, clear business model. I wouldn't consider e-commerce, gambling, advertising industry, shady businesses.

I have three years of experience in software development as a Backend Engineer. I had participated in several projects on different stages of development, including application design from scratch. My primary responsibilities were to work on requirements analysis and functionality implementation, performance analysis, and provide system design solutions. I have a strong knowledge of software architecture design and distributed systems principles. I am experienced in database design with relational databases such as MySQL and PostgreSQL. I have substantial experience in using Python and Go. I have extensive knowledge of algorithms design, concurrency models, programming paradigms, and operational systems. I am a self-organized, responsible, and pragmatic person. I like to work in a team and find a common language with others. I spend much time improving my project design, data organizing, and problem-solving skills.

I am interested in object-oriented and functional programming, network protocols, microservices, electronics and IoT, open-source projects contributor. I got the experience in the international team while building a cloud platform for developers based on OpenStack, k8s, and docker. The entire platform is written (mainly) in Golang (distributed microservices using different transport mechanisms based on network protocols and message queues such as Kafka and NATS). Was building the architecture of the components, services and certain parts of the system.
Open-source projects contributor, speaker and active member of Kharkiv Golang community
I would be glad to work in an international team next to experienced developers building heavily distributed systems, based on microservices, and modern software engineering best practices and preferably Golang. Looking for a challenge with a balance between business and clean architecture.
