Location: Belarus, Minsk

I create software, deliver correct functional and code in time, produce sustainable digital artifacts. I know many techs and use many tools, developed software frameworks and reusable libraries. Experienced in open source, .NET (internals, unmanaged code integration), custom frameworks and API development, Windows, desktop, writing, server side development and enterprise environment (I delete more code than add), technical agility, data. In order to be effective and efficient I tune my thoughts, tools and actions continuously. Computer user since 1993, write programs since 2004, work in companies since 2010, self learner since childhood, do active learning and incremental reading. Applied machine learning is my interest, used against music. Proponent and practitioner of automation, machines should do work instead of humans, like: software generation,testing and deployment; information search and suggestion. IT encyclopedist. Like transparency and science. My titles and roles are - developer, lead software engineer, technical writer, programmer. Sometimes I do - architect, tech lead, team lead, "person who says hard things".
