I am an experienced lead software engineer whose main area of expertise is Microsoft stack, which includes ASP.NET (Framework and Core), SQL Server, Azure, and various front-end technologies. I am familiar with industry-wide best practices, such as SOLID principles, software design patterns, automation testing principles (BDD and TDD) and microservices architecture.

I've built my software engineering experience while working in a variety of industries, including water engineering, financial, retail, railway and defence. I have also played a leading role in various projects and, as well as writing software, gained substantial experience in architecture and design.

I regularly write about software development on my personal website, I have also authored a number of online courses and the following technical books:

Great session as usual as we prepare for interviews. I feel much more confident in the content we covered and have more focus on what I need to work on to get where I want to go.

Great knowledge transfer/practice as always! If you’re looking to level up as a software developer (junior to mid or mid to senior in C#/.NET) Fiodar is the person to go to, hands down. Looking forward to the next session soon and thanks again Fiodar!
