Immediate Altium PCB Design Correction & Revision

URGENT – Altium PCB Error Fixing & Minor Layout Revision I have an existing PCB design created in Altium Designer. The design is mostly completed, but there are several issues that need to be corrected before manufacturing. Only minor modifications and improvements are required; this is not a complete redesign. Tasks Required * Check and fix GND connections that are not properly connected after polygon pour. * Add and correctly position GND vias / via stitching where required to ensure proper connection between GND planes. * Adjust via locations where necessary. * Fix RX/TX connections that are currently missing or not properly connected. * Complete PCB tracks/routes that are unfinished or not fully connected. * Review existing routing and make minor improvements where necessary. * Check polygon pours, clearances, and connectivity issues. * Perform Altium DRC checks and correct errors that may prevent manufacturing. * Make minor component or track placement adjustments if required. * Ensure the PCB is ready for manufacturing. Very Urgent Deadline This project is extremely urgent. The complete work must be finished and delivered within a maximum of 4 hours from the moment the project starts. Please apply only if you are available immediately and can complete the work within this timeframe. Important Requirement The freelancer must not add their name, company name, username, logo, signature, watermark, or any other personal identification anywhere inside the project or delivered files. This includes, but is not limited to: * Schematic files * PCB files * Project properties * Silkscreen * Gerber files * Manufacturing outputs * Documentation * File names * Author or revision information The existing project structure should be preserved as much as possible. Project Scope This is not a PCB design from scratch. The schematic and PCB layout are already mostly completed. No major redesign is expected. The main objective is to: * Correct existing PCB errors * Complete missing connections * Improve GND connectivity * Fix routing issues * Perform final DRC checks * Prepare the PCB for manufacturing Deliverables * Corrected Altium Designer project files * Updated schematic and PCB files * Fully connected PCB layout * Final design with DRC issues resolved * Manufacturing-ready Gerber / fabrication files * Short summary of the changes made Required experience: Altium Designer, PCB Routing, GND Polygon, Via Stitching, DRC, and PCB manufacturing file preparation. Deadline: Maximum 4 hours after project start.
