Guiding light

One of my duties is to uncover information and deliver it, in a timely and convenient fashion. This allows the team to make decisions with more confidence and less assumptions.

Quality advocate

My experience serves the team by advising development methodologies, practices and tools that favor quality. We will attain quality if we share that mindset and agree on a strategy.

Bug catcher

Ideally we forecast issues and prevent them (shift left), but often humans make mistakes and systems fail, that's why we monitor and explore regularly (shift right). Bugs are reproduced, reported and prioritized according to risk.


The team needs to build the right thing (Product) the right way (Engineering). Together, we are the "3 amigos" and we align/challenge expectations before coding. My role adapts to the team's needs, with flow and improvement always in mind.

(User) Friend

We must listen to our users, their pains and their praises, because our services exist to serve them. I seek to make them happy, and also my colleagues! Because a happy team is a productive and resilient team! #OptimiseForHappiness

Eternal student

Technology is constantly evolving, so it's crucial to maintain a curious and open mind. There's always new tools and techniques to discover... and advices from our colleagues too!
