Bronislav Omelchenko
Senior full stack engineer
I am a senior blockchain & full stack developer for 9+ years.
I studied from traditional OOP languages, such as C++/Java to Functional languages, JS and Python. In company positions, I focused to development very secured platforms and writing unit testable codebase. I have very strong knowledge of SQL/NoSQL databases like Oracle, PostgreSQL, MySQL, MongoDB, AWS DynamoDB and so on.
I focused on blockchain technology and DeFi for the last years.
I am also an active user of AWS cloud services for deployment and CI/CD.
I am open to learn any new technologies.
I will deliver perfect result to you.
