Community is a fundamental part of AppMap. Our community members and contributors span the globe, and play a key role in helping us make life better for developers. This blog series profiles members of the growing AppMap community and shares how they use AppMaps in their daily work. Enjoy getting to know everyone!

On Getting Into Software Development
I studied engineering at ULB, the French-speaking university in Brussels. I fell in love with programming and decided to specialize in computer science for my master’s degree.
Haskell is probably my favorite language, I’ve actually taught it for years at the VUB. My work for AppMap is actually my first experience programming outside academia!
On Getting a PhD
When I was doing my master’s thesis, Wolfgang De Meuter asked me to join his Software Languages Lab and get my PhD. Initially, I was interested in studying type systems and static analysis, but I’ve since found static analysis to be like a black box. Developers often struggle to interpret static analysis and too often, the analysis isn’t immediately actionable. So in practice, advanced static analysis is rarely applied outside the realm of safety-critical applications.
Now my PhD is focused on dynamic analysis. In fact, I’m currently working on a solution to implement dynamic taint analysis. Here’s some quick background: Mutable values (aka objects) are easy to track, but immutable values (aka primitives) are much more difficult. Languages often provide abstractions to prevent users from differentiating between two structurally identical immutable values. For instance, the string “foo” can be created multiple times during a program execution. One time it may be a user name, but another time it may be a password. It’s clear these two data don’t carry the same sensitivity level, even though they’re structurally identical. This differentiation is the crux of my PhD work right now.
On Personal Preferences
Spaces all the way! Also I’m team dark theme, for my delicate eyes 👀
My favorite keyboard shortcut is cmd-tab, so I can switch between windows whenever someone sneaks up behind me and I’m supposed to be working!
On Finding AppMap
As part of my PhD, I implemented a general-purpose code instrumenter. Petr, AppMap’s Head of Product, came across it and reached out to me because of it!
I jumped at the opportunity to work with Petr and the AppMap team on AppMap. I think one of the most powerful use cases for the product is using it to understand code you didn’t write yourself.
On Contributing to AppMap
I love how enthusiastic and friendly the AppMap community is. I really appreciate how AppMap has opened up its user base and welcomed people like me to contribute so actively. It’s amazing to witness how people find different, innovative use cases for tools at their disposal, like using AppMap as a record-and-replay tool.
On Life Outside of Work
I like to play video games, but I have a 2 year old daughter so I don’t have much time for it these days. That’s probably a good thing, I never feel great when I game too much. I picture my grandfather looking down at me with a disapproving look telling me, “Mon gaillard, you must play your cards right!”
I also coach kids in my local swimming club. We’re terrible! But we have great team spirit, which I wouldn’t trade for anything. I’m actually a retired competitive swimmer myself. Oh, and I also organize clandestine fight club meet-ups in my basement 2-3 times a week. We do French boxing and amicably punch and kick each other in the head 😂 I find it surprisingly relaxing after a hard day of work and parenting!
