จาก 38,893 รีวิว ลูกค้าให้คะแนน Debugging Experts 4.84 จาก 5 ดาวI am looking for an experienced developer/reverse engineer who has real knowledge of PS4/PSN networking, Demonware services, game APIs, authentication flows, and network traffic analysis. The target game is Call of Duty: Black Ops 2 on PS4/PS5. The goal is to research how the game communicates with PSN/Demonware services and determine how player profile data such as: * Prestige / Level * Stats * Unlocks * Multiplayer profile data is read and updated. I already have legitimate access to the game, my own PSN accounts, and PS4/TestKit hardware for testing. I am specifically looking for someone who understands areas such as: PSN authentication flows, Demonware/Call of Duty backend services, API request analysis, packet/network analysis, PS4 networking, endpoint discovery, and reverse en...
I’m looking for a specialist with hands-on PS4 TestKit/DevKit experience to assess and perform authorized game-file extraction and export for Black Ops 2. I have a physical PS4 TestKit and an original copy of the game. I do not already have a prepared dump. Identifying and carrying out the permitted extraction workflow is part of this project. The objective is to obtain the files that can be legitimately exported from my setup, organized for local technical analysis, together with a file inventory and clear documentation of the process. The specialist must first confirm the technical requirements, required permissions, and what can realistically be delivered. Work must use properly licensed tools and stay within applicable permissions. DRM bypass, unauthorized decryption, leaked d...
I need help breathing new life into an existing product that is suffering on three fronts: it loads slowly, the interface feels clunky, and several core features occasionally break or behave unpredictably. My main objective is to improve—not rebuild—the current solution, so I want a developer who can dive into the codebase, spot the root causes, and roll out solid fixes without disrupting day-to-day use. The work centres on: • Performance: shorten load times and remove any bottlenecks. • User interface: polish layouts, resolve visual glitches, and ensure consistent styling and behaviour across screens. • Functionality: track down logic errors, eliminate crashes, and make sure every advertised feature works reliably. I’ll supply repository access, stag...
My PHP-based site has been accumulating a mix of front-end and back-end problems that now needs to be fixed + i need to implement some new functions.

I’m running Frigate on an MS-01 (13th-gen i9, USB Coral) with eight cameras—six EmpireTechs, one Amcrest, and one SV3C. Each camera provides two streams and everything is routed through go2rtc. Right now the yaml feels bloated and I’m not convinced go2rtc is wired up the right way: CPU usage is far higher than expected, so I suspect an inefficient configuration rather than hardware limits. I need your help to audit, clean up, and fully rewrite the Frigate and go2rtc settings so the system runs smoothly. Scope of work • Review my current and (I’ll share both as soon as we start). • Identify and remove any redundant or conflicting directives. • Make sure all eight cameras connect reliably on both streams. • Tune detection, recording, ...

My Android release hits a road-block on Google Play Console because the SHA-1 key of the .aab I am uploading no longer matches the signature Google has on record. The problem is that I no longer have the original keystore I used back in May 2026, so I cannot simply rebuild and sign with the same credentials. Pls understand I am a 68 y.o Cancer patient with very low income and only can afford $10.00 Can someone be so kind and take that extra step and PLEAE assist me? Here is where I stand: • Mismatch type: SHA-1 key mismatch. • I do not possess the original key at all. • I’m unsure whether the best path is regenerating a new upload key, migrating to a new key signature, or starting a Play support request—so expert guidance is essential. What...
I already have several Hikvision G40 cameras reporting to our own server over the JT808 protocol. We used the JT808Gateway C# library to get things setup The devices are set to raise ADAS and Driver Status Monitoring alarms—forward-collision, lane departure, fatigue, phone use and similar events—yet nothing ever arrives. Because Hikvision’s extensions to JT808 are undocumented, I need someone who has cracked this before to guide the process and write the working integration. I will accept: Code is able to parse the jt808 packets and get the information The original hikvision g40 documentation that lays everything out ( in english )
I have an iOS prototype written entirely in SwiftUI that’s almost ready for prime time, but a few pain-points are holding it back from the App Store. Right now I’m seeing: i made it in openai-codex- i need someone look at the prototype i made, make sure no bugs, all smooth, works well and launch it in the app store - i also need the code from them and access in order to maintain it myself - make sure its all working well efficiently and clean. Launch in app store. then give me code and all for it to maintain myself. Also want someone who can do it in one chunk and happy pay the one off. not paying hourly or extras. • Crashes in several flows • Performance lags on older devices • UI/UX problems that make some screens feel rough Your mission is to hunt ...

READ THE ATTACHED FILE. That is the full brief. This box is the short version only. THIS IS NOT A FROM-SCRATCH BUILD. Do not bid if you plan to “create a webcam website.” We already have one. It is live: StreamLumi is a functioning adult live cam platform — rooms, members, broadcaster login, privates, tokens/tips, chat, and 17 orgs/departments. I need ONE senior engineer who has already shipped or repaired adult cam products (studio + member player + low-latency video + tips + Lovense) to audit THIS existing site A–Z, fix what is broken, upgrade what is weak, and make it commercially tight. If you want to rebuild it in a new stack, leave. If you will inspect the live product first, keep reading. WHAT YOU WILL DO Open as a member and as a model. Then audit th...
My Laravel 8 application is suddenly throwing PHP error messages whenever a visitor opens the main listing page. Other sections behave normally, so the problem is isolated to that specific route. I need someone who can jump in right away, trace the exception, and patch whatever controller, model, blade view, or route definition is responsible. You should be comfortable working through Laravel’s log files, debugging with Telescope or the browser’s console if helpful, and pushing a clean fix via Git so I can review the commit. Once the page loads without errors, I’d like a brief note summarising the root cause and the exact lines changed so future deployments stay stable. Deliverables • Working listing page with no PHP errors • Short summary of the issue and...
I have a live Laravel application where a recent bug is breaking user-facing functionality. I can reproduce the problem consistently and need it resolved immediately while we’re on a screensharing call. Here’s how I’d like to proceed: • Jump on a quick voice/video session (Zoom, Google Meet or similar). • Walk through the failing flow so you can trace the issue. • Patch the code, test together, and push the fix to my Git repo. • Confirm that the affected feature works for end-users without introducing regressions. You should feel comfortable debugging Laravel 8/9, PHP, Eloquent queries, Blade components and typical middleware/auth flows. A solid grasp of Git and the ability to think aloud while coding will help us move fast. If you&rsq...
I have a small V-Card SaaS project that needs a quick but careful tune-up. About five syntax-level mistakes are throwing errors, and three internal routes still aren’t wired together correctly. The problem areas are: • User profile • Dashboard • Sidebar Your task is to locate and clean up the syntax issues, then make sure these three sections talk to each other smoothly so pages no longer return blank screens or 500 errors. I’ll provide the full PHP source plus database credentials; you simply return the corrected files and a short changelog so I can trace what was modified. Acceptance is straightforward: 1. No PHP warnings or fatal errors in the logs. 2. User profile, Dashboard and Sidebar load and link fluidly from the main menu. 3. Existing data r...
My AI-generated CRM is 90 % there, but a mix of functional, interface, and performance glitches keep the core experience from feeling complete. Automations stall, nurture sequences stop midway, and the cross-selling module never fires. I need a developer who can: • Trace and squash the current functional, UI, and speed issues across the entire codebase. • Finish and hard-test the automation engine so every trigger, timer, and conditional fires reliably. • Build out the full follow-up nurture flow—email/SMS templates are ready, they just need proper sequencing and fail-safe logic. • Activate the cross-selling feature set so related-product offers surface at the right moments. Acceptance will be a fully working CRM where: 1. All existing bugs are clo...
I already have RPR’s Broker AVM script and token working when I hard-code a property address, but I need a small JavaScript tweak so site visitors can type any address and instantly see the valuation. Here’s the flow I’m after: • An address field sits right inside the existing widget code—no new layout blocks; it should feel native to the page that already hosts my contact forms, listings, and search tools. • On submit, the script captures the typed address, swaps it into the widget’s Query parameter, and calls the RPR service. • The returned valuation opens in a clean, responsive pop-up modal (desktop and mobile) and stays on the same page. • Everything must run inside Sierra Interactive’s Shared Widget / JavaScript environme...
My local Windows-based Odoo 18 sandbox ran perfectly until a contractor pushed an “ops security hardening” change set. Since then: • Login succeeds only intermittently • The screen often turns blank, key menus disappear, and the session becomes unstable (Blank screen, Missing menus, Unstable session) The culprit likely sits in the custom add-on layer or the recent auth/session code the contractor touched during hardening. I do NOT want a fresh install, random module deletions, or a wholesale rewrite. What I need is a precise repair that restores the original, stable behaviour while preserving the security improvements that actually matter. Scope of work – Inspect the custom add-on, any permission tweaks, configuration edits, or related firewall rules introduc...
I am looking for an experienced **AI Developer / AI Coding Agent expert** to work with me as a **hands-on tutor/mentor** and teach me modern AI-agent-based coding. I have a strong programming background in Python, JavaScript, React, Node.js, VBA, Android, debugging and VS Code, but I am new to modern AI coding agents. I currently **do not have any paid AI/agent subscription** such as Claude, ChatGPT, Cursor, etc. I want to build a **legitimate free/low-cost AI coding environment** using OpenRouter and available free API models/quotas. A major part of this project is to **research and identify the best open-source software/GitHub project** that can: * Connect multiple API keys from different legitimate free providers/models. * Automatically detect rate limits/quota exhaustion. * Switch/...

I have a production-ready Flutter codebase that is misbehaving on Android. The problems show up every time I run the app—no randomness involved—so you’ll be able to reproduce them quickly. What I’m seeing: • UI/UX issues: the user screen doesn't display • Performance problems: janky scrolls and noticeable frame drops on list-heavy pages. • Functionality errors: many API-driven features fail to return data even though the backend is healthy. Your task is to dive into the existing Dart code, locate the root causes and deliver clean, well-commented fixes. Once done, I expect a debug build for review, followed by a signed release APK/AAB. All changes should compile without warnings, run smoothly on Android 8+ devices, and keep the current archi...
