I’m building a marketplace platform that connects buyers and sellers in a time-sensitive, inventory-driven environment. A version of the product has been partially developed, but the core logic and workflows were not properly implemented. I’m looking for a developer to review the existing codebase, determine what is usable, and complete the MVP with a clean, reliable structure. The platform involves routing buyer requests to multiple sellers, handling time-sensitive actions, and managing user states as interactions progress. This requires thoughtful system design, not just basic CRUD functionality.You should be comfortable working with architectural decisions, asynchronous workflows, improving existing work, and ensuring the system behaves consistently under real-world use while building in a way that supports future scalability. The current stack is Laravel (PHP) with an existing backend and database mostly set up. Some integrations have been started, and you’ll have flexibility to refactor or rebuild parts where needed. The goal is to move efficiently while making sure the foundation is built correctly. I’m looking for someone with strong Laravel experience who can take ownership of the system, think critically about how it should function, and make solid architectural decisions. Experience with marketplaces and familiarity with integrating third-party services such as messaging, payments or similar multi-user systems is a big plus. Instead of executing simple tasks, you will need to understand the product intuition to help navigate the MVP phase and deliver a working version that aligns with our long-term direction. If things go well, there’s an opportunity to continue working together on future iterations and long-term support. When applying, please briefly explain how you approach reviewing an existing codebase and share an example of a system you’ve built involving multiple users or real-time interactions.
