About Guillaume

Lead Frontend specialized in Angular, I support teams from product conception to scaling.

I get involved from the very beginning of a project to define the scope, establish a suitable architecture, and lay solid foundations, considering product needs, team dynamics, and long-term performance.

My role is to bring clarity:
– align technical decisions with actual product requirements
– implement pragmatic conventions and best practices
– guide and support the team (both senior and junior)
– ensure a maintainable, performant, and scalable front-end

I also work on existing projects when the first signs of friction appear
(unclear scope, unheeded conventions, tensions in PRs),
to prevent technical or human debt from accumulating.

Objective:
a robust front-end, an autonomous team,
and the ability to say: mission accomplished.
