I’m Vincent Walker, a Product Engineer with over 7 years of experience building and scaling full-stack applications.
I specialise in the Ruby on Rails (8.x) and Hotwire ecosystem, moving seamlessly between technical architecture and user-centric discovery.
Having recently bootstrapped and launched Mercantiworld, I bring a unique 'founder’s lens' to engineering—prioritising high-impact features,
rapid prototyping, and clean, maintainable code. I thrive in embedded product squads where I can bridge the gap between complex business logic
and a frictionless user experience.
Mercantiworld
New
In 2025 I founded Mercantiworld to give small and growing businesses access to bespoke e-commerce
without the cost or complexity of traditional custom builds. The MVP platform supports fully tailored storefronts,
custom workflows, and a flexible Ruby on Rails architecture designed to grow with each brand.
Mercantiworld is a bespoke e-commerce platform I built from the ground up using Ruby on Rails,
Hotwire, and AWS. Designed for independent brands and small businesses, Mercantiworld offers the
creative freedom of custom development without the complexity, providing a flexible, fully hosted solution that adapts to each client’s unique needs.
