ABOUT ME
Senior Software Engineer with 12+ years of experience
Senior Software Engineer with 12+ years of experience
I am a senior software engineer with over 12 years of experience and a great interest in various areas of software engineering and computer science. I like to tackle challenging tasks, especially when there is no straightforward way to solve them. I always try to be engaged in different fields of software engineering, from the field of graph theory and workflow engines to performance and scalability in general.
I participated in bootstrapping a couple of startups and rewrote complex engines for companies such as OriginTrail, Frame/Nutanix and SevenBridges (SDK, computation engine).
My notable previous experience includes:
- Protocol Team lead in OriginTrail (design/implement protocol for supply chain solution on top of Ethereum blockchain from the day one)
- Performance Team lead in Frame, now Nutanix Frame (scaled solution from 2000 to more than 25000 sessions/instances in parallel within ~6 months)
- Solutions architect and Technical lead in SDK team Seven Bridges.

3Box is the best way for developers to manage user data without operating a backend server. The 3Box distributed user data network supports keeping public and private data for Ethereum users. All data is publicly available, but private data can only be decrypted by dapps that the user has given explicit permission. We provide 3Box Hub, an app that allows users to manage their profile and personal storage drive, as well as a JavaScript SDK that makes it easy for developers to add decentralized identity, auth, profiles, storage, and messaging to their web application.
