Hello. My name is Jiří Činčura. And I write code – aka I’m a developer.

I write code in exchange for money because that pays the bills. I also contribute to open-source software. Anything that spans data access layers, business layers, testing, databases, parallelism, debugging, operating system concepts, cloud and scaling, programming language constructs and whatever is in between. I’m a project lead for .NET provider (and related providers like Entity Framework Core, Entity Framework and DDEX) for Firebird (the database). I helped with .NET and Entity Framework providers for NuoDB. I’m Microsoft Most Valuable Professional and also Microsoft Certified Trainer.

You can find a lot of free code here on the blog and on my GitHub. If you use Firebird and like .NET, you might be interested in FbNetExternalEngine project or FirebirdDbComparer. My application ID3 renamer might help you to keep your MP3 files in order.

When not writing code I’m speaking, teaching and writing about topics above. I speak at conferences, user groups, companies, … and to whoever will listen. And write even for just a single reader. Because I like doing it.

And finally I also run and do yoga. I like running long, so called ultra, distances. Preferably in the mountains. For yoga I’m practitioner of Ashtanga yoga, because I like the connection between physical and mental self. But lately, I’ve been neglecting these hobbies.

I would love it if you would subscribe to my blog’s feed. I’m also on social media, mostly Twitter. If you just want to email me, go ahead send your message to

To support my work, including this blog and my open-source coding, Github Sponsors is one way to do it.
