ProxySock - B2B Proxy Marketplace (Canadian Startup)
LiveB2B SaaS platform built from scratch. I designed the initial architecture and built the customer dashboard, product catalogue, ordering, account management, and payment flows, including Stripe checkout with webhook-based order processing, plus Paystack and crypto payments. As usage grew to 3,000+ daily transactions, I worked with another backend engineer on the move to Ruby on Rails and PostgreSQL, and on self-managed VPS hosting with Docker and Kamal.
