WHY HIRE A PRODUCT DEVELOPER
An experienced design partner without the agency overhead
I'm Sebastien, an independent product developer working with founders and small teams across industrial design and UI/UX. The goal is simple: expert product thinking, fast iteration, and end-to-end delivery without the cost or complexity of a traditional studio.
Solo founders are stretched across every role, with limited budget to validate an idea before committing to it.
Startups are under pressure to move fast without the cost of multiple specialist hires.
SMEs need specific expertise on demand and consistency across a growing range, without staffing up permanently. I work as a single, flexible partner that adapts to whichever of these you're facing.
01
Faster Product Development
One expert across ID and UI/UX. Fewer handoffs, faster decisions, quicker prototypes.
02
Cost-Effective Expertise
Expert product expertise without the cost of an in-house team or agency.
03
More Cohesive User Experience
Consistency between physical products and digital interfaces across every touchpoint.
04
Flexible & Agile Collaboration
Adapts to changing priorities and rapid iteration. Built for founders and small teams.
WHAT I OFFER
Three core practices, end to end
I support solo founders, startups, and SMEs across the full journey of bringing a product to market. I do the work myself, and bring in trusted specialists when a project calls for it.
Strategy
WHAT'S INVOLVED
Product-market fit, competitor analysis, roadmapping, project planning and management, product viability.
Design Development
WHAT'S INVOLVED
From sketch to 3D model, concept development, basic prototyping, visualisation.
Manufacturing & Launch Support
WHAT'S INVOLVED
DFM/DFA analysis, manufacturer sourcing, marketing visuals, user feedback analysis.
