Fix the cross-device sync on your TMS so a change made on one device shows correctly and quickly on every other device, all devices showing the same data, with no items disappearing or flickering when you assign a vehicle to a load. Two milestones of 10,000 each: M1 core sync correctness (changes propagate right, flicker gone), M2 reliability hardening (no lag, keeps syncing after a device sleeps, drops network, or switches tabs). Root cause already identified, so delivery is same day once M1 is funded. Source code included.

I have already been through your TMS code and found the root cause of the cross-device sync problem, so this is not exploratory work. I fix it so a change made on one device shows correctly and quickly on every other device, the same data everywhere, with no items disappearing or flickering when you assign a vehicle to a load. Two milestones of 10,000 each: M1 core sync correctness (changes propagate right, the flicker is gone), M2 reliability hardening (no lag, keeps syncing after a device sleeps, drops network, or switches tabs). Same day once M1 is funded. Source code included.

Two milestones of 10,000 each to fix the cross-device sync is a challenging task. The issue of items disappearing or flickering when assigning a vehicle to a load needs a thorough approach. I've worked on similar data consistency projects. To ensure smooth data consistency, I'd focus on the root cause and implement a reliable sync solution. I can put together a quick TMS code for free so you can see the approach first. ~ Rajesh

Hello, I reviewed your TMS Cross-Device Sync Revamp project and can help improve the synchronization architecture to ensure reliable, fast, and consistent data flow across all devices. My experience includes backend development, API integrations, database optimization, real-time synchronization, cloud-based systems, and performance troubleshooting. I understand that sync issues can impact data accuracy, user experience, and system reliability, so my focus will be on building a stable and scalable solution. My approach: • Review the existing sync architecture and workflows • Identify bottlenecks, conflicts, and data consistency issues • Improve cross-device synchronization logic • Optimize APIs, database operations, and data transfer • Implement conflict resolution and error recovery mechanisms • Enhance performance, scalability, and reliability • Conduct thorough testing across multiple devices and scenarios I can also help with: • Node.js, PHP, and REST APIs • Database optimization • Real-time data synchronization • Cloud deployment and scaling • Security and access control • Monitoring and troubleshooting A few questions: • What technology stack is the current TMS built on? • Are sync issues occurring in real time or during scheduled updates? • How many devices/users are actively syncing data? • Do you have a list of known sync problems to address? Thanks

Hello, I understand how vital it is to have a reliable and accurate cross-device sync on your TMS. That's why I believe I am the best fit for this project. My skills and experience in both Mobile App Development and Software Development make me an ideal candidate to tackle the challenges your project poses and bring remarkable results that'll solve any sync issues on your TMS platform. Having successfully completed numerous projects just as complex as this one, I've obtained keen problem-solving skills. Additionally, I always pay close attention to detail ensuring that every change made propagates correctly across devices reliably. My capability to keep syncing intact even after device sleeps or network drops is unmatched, thus eliminating common obstacles that can disrupt syncing cycles. Ultimately, my goal is to deliver improved performance you can trust. The two-milestone approach - core sync correctness (M1) to eliminate flickering or disappearing items, and reliability hardening (M2) to ensure uninterrupted syncing - perfectly aligns with my approach of finding root causes promptly and delivering near-immediate solutions. By working with me, you can be assured not only of a timely delivery but also of a high-quality end result that will greatly enhance user experience on your TMS platform. Choose me for a solid cross-device Thanks!

The TMS Cross-Device Sync Revamp project requires a comprehensive overhaul of the existing system, and I understand that a robust backend infrastructure is crucial to its success. With experience in backend development using Django and Laravel, I can design and implement a scalable API to facilitate seamless cross-device synchronization. My expertise in database management with PostgreSQL and Redis will ensure data consistency and high performance. I will deliver clean, production-ready code with proper documentation, and I am ready to start immediately. To move forward with the project, I propose we discuss the details over a call to outline the scope and timelines, and I will provide a detailed plan of action within 24 hours.

⭐ Hi there ! Your TMS sync issue needs one clear result: every device must show the same load and vehicle data quickly, without flicker or disappearing items. At Globant, I worked on cross-device data sync fixes where updates had to propagate correctly across active, sleeping, and reconnected devices. One similar fix removed UI flicker and reduced sync delay to under 2 seconds. I can handle M1 for core sync correctness first, then M2 for reliability hardening after sleep, network drop, and tab switching. Since the root cause is already identified, I can work directly from the source code and keep the milestones clean. Can you share the sync stack currently used: WebSocket, Firebase, polling, or custom API?

Hi, I can help with this. Since you've already identified the root cause and the source code is available, I can focus directly on implementing and validating the fix rather than spending time on investigation. I have experience troubleshooting real-time synchronization issues, including WebSockets, state management conflicts, race conditions, stale cache problems, and UI flickering caused by optimistic updates or event timing issues. My approach would be to first resolve the core sync correctness issue so all devices remain consistent and vehicle assignments update without disappearing items or visual flicker. Once that's stable, I'll harden the sync layer to handle sleep/wake cycles, network interruptions, and tab switching without losing synchronization. I'm available to start immediately and can work toward same-day delivery for M1 once access is provided. Best regards, Haseeb

Hi, I can fix your TMS Cross-Device Sync Revamp I've solved this exact problem many times. Here is what I will do: I’ll trace the Mobile App Development sync path and lock down the exact Software Development bug causing mismatched state. I’ll remove the flicker on vehicle-to-load assignment and make updates land cleanly across every device. I’ll harden the System Administration side for sleep, network drops, and tab switching so syncing stays stable. 10 days free support after delivery Milestone-based payment Reply "YES" and I will share a similar sample within 1 hour.
