Little Big Event #1 – Types everywhere!


Last Thursday, I was at Clermont-Ferrand in France to talk about the TypeScript type system. It was a special event organized by Mug In Clermont, LavaJUG and Clermont’ech.

During my talk, I explain what is TypeScript and how it works. I also did a live coding session to demonstrate how to use type concept like Intersection, Union, Guards, MappedConditional  and infer. To be honest I don’t really do a lot of live coding sessions because I don’t like demo effects, but it’s near impossible to explain those concepts with just slides… and it was fun actually 🙂

There were a lot of developers during this event, the Clermont community is really active and friendly. It’s probably one of the best community event I did this year, thanks to organizers for the invitation, hope I can comeback later!

As always slides are available on Speaker Deck here. Also, live coding sources are on Github.

Criteo Meetup – MediatR


Yesterday I gave a talk at Criteo Labs meetup about MediatR, a library built by one of the most inspiring C# developer: Jimmy Bogard.

I demonstrated how to use MediatR to implement the CQRS pattern in a Microservice built with Asp.Net core. I used CQRS a lot and it’s definitely a great pattern, it increase maintainability and organisation of your projet. If you like Domain Driven Design, it’s a great way to focus your development on domain representation & logic.

Slides are available on Speaker Deck here.

DevFest Paris 2019 – TypeScript: Why? When? How?


Last Friday (8th, February 2019), I talked about TypeScript at DevFest Paris 2019. This presentation is an updated version of the one I did at Microsoft Experiences 2018 with my mate Félix Billon.

It was really a fantastic event with a lot of great speakers and topics. I met a lot of amazing developers. We also had a lot of interesting feedbacks on our session TypeScript: Why? When? How?. I really want to thank you all for that, it helps us to improve our speech! The speaker dinner was also a good time and it was the first time I shared a meal with some Google engineers 🙂

Slides can be find on Speaker Deck here.
