À propos de moi
Software engineer and mobile team lead with 10+ years of experience (Flutter, Dart, Node.js). I build websites and web apps, backends and APIs, CRMs and admin tools, and Flutter apps, and I fix bugs in existing projects. I also do data cleanup in Excel/CSV, logo and social media graphics, and translation and localization. Based in the US, fluent in English and Russian. I confirm scope before starting and tell you upfront if something isn't a good fit.
