About Alexis

I am a Senior Software Engineer with a simple goal: to make complex engineering accessible, both in the codebase and for the team.

I appreciate well-oiled mechanics and clear architectures, building predictable systems with clear and intuitive rules for both tech and business (and I admit, code that's easy to grasp also prevents me from being too frequently asked to explain it).

On a daily basis, my role revolves around three axes:
- Product and Impact: I challenge the status quo. I push to question the 'why' behind things, even if it means 'pushing back' on certain topics to make massive progress on those with the most value.
- Bridging Tech/Business & Team: I elevate the team through demanding code reviews (when I can get out of my development bubble) and translate our complex technical challenges to the business teams without losing them along the way.
- Pragmatic Engineering: I'm not afraid to automate alienating tasks to improve our DevEx and CI, nor to get my hands dirty with infrastructure to empower the team with more autonomy.

Here's what my colleagues say about me:
💬 "Secures architectural choices and accelerates the skill development of others through demanding yet supportive code reviews."
💬 "Strongly embodies benevolence through availability and patience in knowledge transfer. He was a real gateway to structuring concepts like Hexagonal Architecture."
💬 "He has a lot of technical expertise but knows how to explain it very easily to someone non-tech, which is very pleasant on a daily basis."
