Gui and save realtime process debugging code
I have two standalone Python scripts: • a real-time antenna control loop that streams data perfectly on its own, and • a small Tkinter interface with Start, Stop, and End buttons that also works when run separately. As soon as I merge them into a single file, the window still appears but none of the buttons respond. The antenna logic keeps running in the background, yet every GUI click is ignored, so I end up force-closing the app. I’m looking for someone who can: 1. inspect the merged code, identify why the Tkinter callbacks aren’t firing (likely event-loop or thread conflict), 2. refactor or restructure it so the GUI remains responsive while the antenna loop runs, and 3. hand back a single, clearly commented .py file plus a brief summary of what you fixed. The ideal result is: • Start → begins the real-time antenna routine; • Stop → pauses or safely halts that routine without freezing the window; • End → closes the program and releases any resources cleanly. and when u start to stop save the process as a file No need to alter antenna functionality—just make the integration solid and maintainable so I can learn from your approach.

Web3 Crowdfunding Platform
Project Description I have an existing Web3-based crowdfunding platform built with React (Vite), Node.js, MongoDB, and Ethereum smart contracts. The platform is already implemented and functional, but it contains specific technical bugs that must be fixed to make the system stable and production-ready. - Important: This is a bug-fixing and stabilization project only. No new features, no refactoring, and no redesign are requested. The selected freelancer will work strictly within the existing architecture and codebase. - Exact Bugs to Fix (3 Only) 1. MetaMask Connection State Bug Wallet connects successfully, but after page refresh or route change the frontend loses the wallet state while MetaMask remains connected, causing inconsistent UI behavior. 2. Transaction Feedback Bug ETH transactions are sent to the blockchain, but the frontend does not reliably display success or failure status, leaving the UI stuck in a loading state. 3. Smart Contract Revert Handling Bug When a contract call fails (revert, gas issue, or invalid input), the error is not properly captured or surfaced to the user, making debugging and user recovery impossible. - Objectives Fix the above bugs without changing system design Ensure consistent wallet and transaction state handling Improve reliability of Web3 interaction feedback Maintain clean, minimal, and maintainable fixes - Deliverables Fully fixed bugs listed above Verified working flows (wallet → transaction → UI update) Short technical summary explaining: Root cause of each bug How it was fixed - Freelancer Requirements Strong experience with React debugging Hands-on knowledge of Ethereum & MetaMask behavior Ability to debug Ethers.js / smart contract interactions Comfortable working with an existing codebase Clean fixes — no hacks, no unnecessary changes - Budget & Timeline Fixed-price or hourly (to be discussed) Milestone-based payment Fast turnaround preferred
Web application Expert
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.
