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.
