Job description

This position is 100% remote, with flexible daily / weekly hours (part-time).

We’re looking for a Software Architect contractor with strong expertise in composable modular architecture and event-driven design to support the next evolution of Sharewise: our marketplace framework that helps entrepreneurs and small businesses launch world-class platforms faster.

This isn’t a “keep the lights on” role. You’ll be shaping the backbone of a framework designed to democratise marketplace creation and empower communities. Sharewise is built on 12+ years of CobbleWeb’s experience delivering high-performance marketplaces, and we’re now evolving it into a platform that is modular, event-driven, and future‑ready.

We need someone who can :

• Audit and strengthen module isolation (reduce hidden coupling).
• Push us toward a stronger event‑driven architecture (pub / sub over direct calls)
• Lay the foundation for customisation: moving from fragile inheritance overrides toward clear extension hooks, composition patterns, and well‑documented integration points. This is about more than code style; it’s about making Sharewise a framework where developers can confidently adapt and extend features without breaking core stability.
• Make the platform easier to scale, extend, and maintain, both for our team and for external developers.

Stack

• Backend & Core: Node.js (TypeScript) - Fastify for REST, Apollo for GraphQL, TypeORM, Redis, PostgreSQL
• Side deps: chalk, chokidar, commander, winston, class-transformer, class-validator
• Frontend: Next.js v15 & React v19
