Since 2016 I am an active member of Topcoder community, known as birdofpreyru; and I earn my living mostly by competing in paid software engineering challenges at Topcoder, and sometimes acting as a technical project manager (copilot) for some of their compeitions. Within these years I won two Software Development Champion titles in Topcoder Open tournaments (in 2020, and 2017); and I was distinguished as one of Topcoder's Most Valuable Players.
Below is the list of my victories in public Topcoder challeges, and of medium-to-large competitions I was in charge of as a technical manager (copilot). Beside these, I have also worked via Topcoder on numerious private tasks and projects for large corporate clients, which cannot be listed here because of their NDA terms.
Here are some open source libraries I have created/forked, and currently maintaining (these are mostly tooling for React development):
