Who am I

My name is Lyuben Blagoev (pronounced [ljuben blʌ'goev]). I am a software engineer with over 20 years of professional experience. Throughout my career, I have worked with a wide range of technologies, primarily Java, Spring, SQL Server, and JavaScript, contributing to both backend and frontend development.

I specialize in software development and system architecture, with a focus on Java, HBase, and distributed systems. I have extensive experience with Java, Spring, and SQL, as well as building modern frontend applications using React. Additionally, I have worked with Go for developing sidecar tooling. I am particularly passionate about designing robust systems, as well as debugging and solving complex technical challenges.

I hold a bachelor's degree in Industrial Automation and Information Technologies, with a background in control systems engineering.
