👋 Hello, I’m Alexander Korostelin (@flexits).
I am an engineer focused on hardware-software integration, with extensive background experience in industrial electronics repair and maintenance. My professional work involves developing integrated systems—from bare-metal embedded control units to server backends.
Beyond my engineering work, I am also the author of the book «Импульсные источники питания. Элементная база, архитектура и ремонт» (Moscow: Solon-Press, 2020), which covers the principles of operation and troubleshooting of various SMPS designs. Additionally, I have authored a series of technical articles featured in «Хакер» and «Ремонт и Сервис» magazines.
