CV

Senior Software Engineer with strong academical background  and 10+ years of hands-on SE experience. I'm specialising in Distributed Systems  with a bias towards Trading and Cryptocurrencies. 

Most of my career I've been working on world's top enterprise projects enabling companies to achieve their business goals.

Getting bored of enterprise, I've found my passion in FinTech and Web3. 

My Software Engineering skills, proactiveness and deep knowledge of cryptocurrencies and Web3 enabled me to start and run a cryptocurrency copy-trading platform and an advanced extensive arbitrage platform. The latter one allows user to profit from market inefficiencies across a dozen of tier1 exchanges.

While working on these projects I've reported dozens of bugs in the API of these exchanges while contributing with open-source API client libraries.

In addition to that,  I have an experience building crypto exchange from scratch, so I know how to do it efficiently and what can be out-sourced.

If you have to work with crypto exchanges to achieve your business needs - you won't find a better partner!
