My name is Florin Coros and On Code Design is my blog. I write here about my experiences and ideas on organising code in an efficient way, in a way that allows us to manage and change it long after we've written it. I like to call this Code Design.

I like to introduce myself as a passionate software developer. I put a lot of care and attention in any work I do. I also call myself a software engineer or a software architect.

I am particularly interested in distributed applications, software design and unit testing. In the last years I have developed an increasing interest in software quality and I strongly believe in quality driven products.


Since 2015, I've been self employed and available for hire. Since then, I work as a consultant, developer, trainer or coach with different teams in various fields and contexts.

Together with some friends we have founded iQuarc, a team of elite professionals with mature skills.

We help different companies and teams to deal with divers software related problems. We also help other developers to improve their skills by sharing our experience when we join their teams, or by doing training or customized coaching sessions.


In 2016, I have joined InfiniSwiss as a partner. I contribute to building a team of passionate developers who delivers high quality software development services and products.

I also like sharing my ideas and experiences by speaking at different user group events or developers’ conferences. Here are some of the talks I did.

You can find more details about my professional experience by following my LinkedIn profile. I keep it up to date.

About my personal life, the basics are simple. I live in Cluj-Napoca with my wonderful girlfriend who is also a software developer. I am very close to my brother, who is also a software developer. So building software is, and is going to be, a big part of our lives.

I like a lot playing GO. When I was younger I used to go to local competitions. If you are a player you may find me on one of the online game rooms.

I also like listening to rock music, traveling and going to live concerts.
