About

I am a programmer with 10 years of professional experience. I have had an opportunity to work for the leading financial institutions developing tools for investment banking and risk management. I worked with a broad spectrum of technologies although the most experience I gained in the .NET framework. I can work proficiently with Windows, macOS and Unix operating systems. I have experience also in dev ops and gathering business requirements form users. Moreover I have ability to solve non standard problems thinking out of the box. I am looking for a job providing challenging tasks that will help me to develop my skills.

Employment history

AI/ML Engineer, Blockhunters 2020/02-Now Design and development of a symbolic virtual machine for automated software verification. At Blockhunters we develop tools that enable high quality unit and regression tests to be automaticaly generated from raw source code. Our goal is to save programmers' and testers' time, which in turn, leads to increased employee productivity and lower costs related to software testing. Tests are generated by analysing program execution paths with a symbolic virtual machine, which is able to find corner cases and obvious errors, and then report them to developers. Thanks to WebAssembly our tool supports most of the popular programming languages and environments. This approach saves a significant amount of the time which would be needed to implement it in different environments

Best back-end engineers I've ever worked with...​

“I interviewed about a dozen different firms. DevsData LLC is truly exceptional – their backend developers are some of the best I’ve ever worked with. I’ve worked with a lot of very well-qualified developers, locally in San Francisco, and remotely, so that is not a compliment I offer lightly. I appreciate their depth of knowledge and their ability to get things done quickly. “
