    14+ years of experience solving problems with web and hybrid applications in various domains (e-commerce, banking, healthcare, education, gaming, media, real estate, governmental services) ranging from pretty small ("one-man army" kind of projects) up to enterprise-scale (hundreds of developers distributed all around the globe). Primarily interested in JavaScript/TypeScript-based development (Node.js/Angular/Vue), but I know my ways around other ecosystems as well - including, but not limited to, PHP, Perl, and Ruby. The same goes with databases (from MySQL and MongoDB up to exotic stuff such as Neo4j). These days I'm mostly busy with my full-time job but can help (I mean a LOT) both as a consultant and as an implementer - if the project and all the terms around it will fit. If all this sounds interesting, but you are still in doubt and want some proof, you can check my profile at StackOverflow. I love helping others with their tasks, and with time became quite proficient in it. I'm in the top 0.14% of contributors overall with a reputation around 105K - and going up.
