I am a Microsoft MVP and a lead/senior software engineer with over a decade of professional experience. I primarily specialize in .NET and Microsoft stack. I am enthusiastic about creating well-crafted software that fully meets business needs. I enjoy teaching aspiring developers and sharing my knowledge with the community, which I do both as a volunteer and commercially. I have created online courses, technical books, and other educational content for major publishers like Apress, Manning, Packt, Educative, etc. I also provide live mentoring services, both to groups and individuals. Some of my books made it into the number one bestseller spot on Amazon and LeanPub. My books include "SignalR on .NET 6 - the complete guide", "The battle hardened developer", and "The easiest way to learn design patterns". Throughout my career, I have developed software of various types and various levels of complexity in multiple industries. This includes a passenger information management system for a railway, distributed smart clusters of IoT devices, e-commerce systems, financial transaction processing systems, and more. I have also successfully led and mentored teams of software developers.
