A creative programmer and a heavy Linux user. Started tinkering with computers at age of 13. Since then, had a variety of experience in systems programming (C/C++), OS administration (Linux, Windows, macOS), scripting (Bash, Perl), and web (LAMP, Python & Django, HTML & CSS, JavaScript, Node.js). For the past 6+ years my main interest lies in full-stack development of web applications, JavaScript, and everything JavaScript related (Node.js, Electron, Gjs, etc.).

I believe in the future of web interfaces to just about everything you can imagine! JavaScript is getting its grip on all major domains of human interaction, and I will be there to harness all the new possibilities. I am continuously looking into new ways to unleash the hidden potential of The Language That Can - of the language JavaScript!

Another area of interest is working with C/C++. Building applications involving computer vision, real-time video processing, 3D rendering, and system programming in general. IoT (Internet of Things) and hardware (embedded PCs, robotics, flying drones) are two domains where I participated in some very interesting projects.


Over the past 12 years I worked in many companies, and on many projects. I know people who keep working at a single company for 5-10 years. Fortunately (or unfortunately) in the past I had to switch projects many times. Some reasons for relatively short stays with a project:

Below is an accurate list of what I did so far in my career as a software engineer.

Freelance: 2019 - now

Because of the Covid-19 pandemic, and because I became a father a second time, I switched to doing freelance work remotely. A few things I am engaged in now:

Scout Gaming Group: 2018-2019

I joined this company to do full-stack development, but it became quickly apparent that my knowledge of Docker, and infrastructure in general, were very useful at the time. I was transitioned to the DevOps team, and helped migrate everything from standard server setup to GCP. I did a lot of Kubernetes work, but also helped prototype new services in Node.js.

DataSpark: 2018

Blockchain, software architecture, CS research.

Donnelley Financial Solutions: 2016 - 2018

Working on ActiveDisclosure, and ActiveFinancials web applications. Helping to modernize them, moving from old MS Office based plugins to MS Office Online ecosystem.
