ABOUT ME
Developer - Architect - PhD in Software Engineering - Humanist
Developer - Architect - PhD in Software Engineering - Humanist
Young generalist engineer graduate from Icam de Nantes (France), I am fond of a lot of stuff. Most of them are linked to new technologies, IT, and software development.
I am currently in charge of R&D at Startup Palace, a company providing lots of services to startups, where I actually do many different things (which is something I like!). For example, I am helping CTOs of different startups with various tech problems they encounter. I also recently defended my PhD thesis in Software Engineering.
I care about Open Source, and I like when my code is simple and maintainable.
I'm here to meet interesting people with interesting problems, and do my best to help them! (Note: in case you wonder, helping beginners is an interesting problem)

Functional programming is a trending topic, especially in web development. People often try to explain its essence with too theoretical concepts (monads) or too superficial points of view (it's just lambda functions). I can help you understand and feel how the related concepts work, why they matter in the real world and how to use them in your applications. Besides using it literally every day, I gave presentations on this subject in many international conferences.

I wrote several kinds of programs using Scala, for example: web applications (using Play! 2), AMQP workers and even CLI tools. It was also my choice for building prototypes during my PhD: it has a good ecosystem (libraries, community, ...), it can ensure a nice level of consistency (types are checked at compile-time) and I can generate a portable JAR file.

I'm writing JavaScript at work for 4 years, but I started as a hobby 12 years ago. I wrote JS primarily for the frontend, but I have also targeted backend, tooling and even userscripts! Few years ago I wrote (but never really finished :/) a library to partially parse SQL syntax: https://github.com/dsferruzza/simpleSqlParser/tree/v2

I'm writing JavaScript at work for 4 years, but I started as a hobby 12 years ago. Like a lot of PHP developers, I wrote several personal web frameworks; I guess nobody is perfect ^^ At least this is the kind of experience that helps to put things in perspective! These days I mainly use Laravel for writing small/medium-sized web applications.

I use GitLab CI for personal and professional projects, in both gitlab.com and a self-hosted instance. I think it offers a good balance between simplicity and power. I have successfully setup simple or complex build flows in different teams to build, test and automatically deploy software.

I use NixOS on several servers and on a personal laptop. It is not perfect, but I believe it has a great potential, nice features and it saved me several times! I'm not really an expert, but I gathered a bit of experience using it and writing packages and modules. I'd love to share it! I also gave presentations in several conferences to introduce it to beginners.

David did a great job helping me to debug a failing NIX package that I was trying to build. He has a lot of knowledge in NIX OS and shell scripts in general. I will definitely take another session if I have more issues. I highly suggest him.
