Senior Blockchain / Full-Stack Developer Needed to Rescue E-commerce Project We’re building an e-commerce platform that handles global shipping and international orders, but the project is hitting serious roadblocks. The codebase exists, but the system isn’t ready for launch, and our current team is struggling to fix complex issues. We need a senior developer who can step in, understand the existing architecture, and stabilize the platform before we go live. The platform combines a traditional e-commerce flow with blockchain elements. Smart contracts manage payments, tokenized rewards, and some transaction logic, while a Python backend handles order processing, inventory, and shipping coordination. The frontend is built with React.js. Right now, blockchain interactions are inconsistent, some transactions fail, and data between the frontend, backend, and smart contracts isn’t always syncing correctly. This isn’t a new project — it’s about rescuing something that already exists. We need someone with hands-on experience debugging Solidity contracts, resolving state issues, and integrating blockchain reliably with e-commerce systems. You’ll also coordinate fixes across the Python backend and React frontend, ensuring orders, payments, and shipping workflows function correctly. We’re looking for a problem-solver who can take ownership, work independently, and bring a production-ready mindset. If you’ve helped pre-launch blockchain projects get back on track, understand cross-border e-commerce complexities, and can ensure the system is secure, stable, and ready for users, you’re exactly who we need.
