About Me

The VWA

I'm Vincent Walker, a Senior Software Engineer with over 7 years of experience architecting and scaling production-grade full-stack applications. I specialise in the Ruby on Rails 8 and Hotwire ecosystem (Turbo + Stimulus), with deep expertise in React, AWS, and building maintainable, high-performance systems.

As the founder of Mercantiworld, I took the leap in 2025 to build and launch a complete e-commerce platform from the ground up. This experience sharpened my ability to own products end-to-end, from technical architecture and scalable infrastructure to secure payments and user experience. I’m now running Mercantiworld as a side project and am actively seeking my next full-time Senior Software Engineer role, where I can bring strong technical ownership, product intuition, and rapid delivery to a collaborative team.

  • Designed and implemented a multi-site architecture with secure multi-provider payment integrations (Stripe + Braintree)
  • Built and stress-tested a robust AWS infrastructure (Elastic Beanstalk, S3, Lightsail, etc.) for high availability and future scalability
  • Managed the complete product lifecycle as sole engineer: UX design, backend architecture, automation, technical documentation, and deployment pipelines
