Hey, I'm Maxime
Product Designer
I design scalable B2B and SaaS products, from marketplaces to AI-driven features. Drawn to design systems and building things that balance business goals with user needs.

Signals
Took Signals from a monitoring tool configured by hand to AI-powered Signal Agents: guided onboarding, guided outreach, auto-sourcing and an optimization agent.
People Database
Took the People Database from a wall of filters to natural-language search, with a redesigned filter system, personas and a richer company record.
Enrichment
Took enrichment out of the flows where it was hidden: a standalone entry, harmonized results, company enrichment and custom provider waterfalls.
Contacts, Companies & CRM
Designed the tools that keep a contact database clean and in sync with the CRM: configurable duplicate rules, merging and overwrite rules.
How I work
MethodDiscovery & research
User interviews, a heuristic audit of what exists, and alignment with product and business goals before the first mockup.
Architecture & flows
Journey mapping, user flows, and low-fidelity wireframes to validate structure before investing in visual detail.
Prototyping & testing
Fast, AI-assisted prototypes to explore ideas and get to a testable version quickly, iterated in short cycles rather than shipped all at once.
Design system
Tokens, components, and living documentation, built to be picked up as-is by engineering teams.
Delivery & follow-up
Specs in Dev Mode, design QA after implementation, then usage metrics tracked once live.
