Senior Full-Stack Developer to Build/Rebuild Our Custom Website & Ecommerce Platform

We're Accelerator, a sports supplement company focused on enhancing athlete performance. We need an experienced developer to build a custom web application / ecommerce platform for us — or rebuild and migrate the one we already have. Off-the-shelf themes won't cut it; we have specific business logic (subscriptions, athlete accounts, stack/bundle builders), integrations, and performance requirements. The work is a custom build, not a template drop-in. Depending on your background this could be a fresh build, a migration off our current platform, or extending an existing app with new features and API integrations. What the project involves: - Custom back end (Laravel / PHP / MySQL) with a modern JavaScript front end - Ecommerce or portal functionality: supplement catalog, athlete accounts, checkout or B2B ordering for teams, gyms, and retailers - Third-party API integrations (payments, subscription billing, ERP/CRM, fulfillment and internal tools) - Clean, fast, responsive front end — performance matters to us as much as it does to our athletes - If a migration: moving data off the old platform with zero data loss Please share two or three custom builds you've shipped that are close to this — ideally with a live URL — and a one-line note on what you built and the stack. Point us to the project that best matches our problem, not just your longest list. We'll scope timeline and budget on a quick call once we've seen requirements.
