Who am I

My name is Lyuben Blagoev ['ljuben blĘŚ'goev]. I am a software engineer with 15 years of professional experience. I've worked with different technologies, mainly (but not limited to) Java, Spring, SQL Server and Javascript. I've worked on both the backend and the frontend.

My days consist of being a software developer, architect, systems administrator, DBA, network and data center guy and everything in between. I love to design, debug and fix things, no matter whether in software, the datacenter or the network.

I studied control systems engineering and I hold a bachelor's degree in industrial automation and information technologies.

You can find more information about me and my experience in the section below and on my LinkedIn profile. If you want to contact me, feel free to go to the contact page and send me a short message.
