    Recover InnoDB Data & Backup

    My MySQL 5.5.18 instance is limping along after a corruption event—system tables open, but every InnoDB table throws errors. The server is only “partially functional,” so I have powered it down and kept all data files intact (ibdata, ib_logfile*, .frm, .ibd, relay/binlogs, ). Remote log-in isn’t possible; you will need to walk me through everything step-by-step while I work directly on the box. What I need is a complete, reliable FULL backup of every database, including the damaged InnoDB tables, so I can spin up a fresh 5.7+ server later. I am comfortable following detailed terminal commands; I just need an expert plan and real-time guidance to: • Mount the data directory in a safe environment (ideally using Percona XtraBackup, mysqlbackup, or a comparable t...

    Facebook Marketplace Car Scraper

    I need a turnkey script that logs into Facebook Marketplace, navigates through every active “Cars for Sale” listing, and extracts only the seller’s contact information—name, profile URL, any displayed phone number, and the direct Messenger link. The script should save these fields to a clean, well-formatted CSV and refresh the file automatically every day without manual intervention. Please build it in Python; Selenium, Playwright, or a similarly reliable headless solution is fine as long as it can handle Facebook’s infinite scrolling, dynamic content, and occasional anti-bot measures. Cookie-based login or a secure credential file is acceptable, but the process must stay within Facebook’s terms of service. I’ll deploy this on an Ubuntu VPS, so in...

    I need an experienced Linux/PHP/Apache network engineer to troubleshoot and fix a captive portal running on Ubuntu/Linux.

    I need my entire WooCommerce store—files, database, and all media—moved from its current host to a fresh Linux VPS. Alongside the transfer, please configure the new server so it runs WooCommerce smoothly and securely. That means setting up the full stack (Apache or Nginx, PHP, MySQL or MariaDB), enabling SSL, and applying the usual performance and security tweaks a busy online shop needs. Once everything is copied over, I will need you to update any paths or configs, switch DNS when ready, and confirm that orders, plugins, and theme functions work exactly as before. A brief downtime window is fine, but I would like a clear schedule in advance. Deliverables • Complete site migration with zero data loss • VPS tuned for WooCommerce on Linux • SSL and basic h...

    sits on WordPress with Elementor, several SEO and performance plugins already in place, yet Google continues to reject our AdSense application for vague “policy violations.” From what I can see, the problem is most likely rooted in technical issues rather than content quality or UX, so I need a specialist who can verify that hunch, uncover every hidden compliance red flag, and correct it. Scope of work • Crawl and audit thElementord-to-endpolicElementore, plugins, Core Web Vitals, schema, and any server-side configurations and as to pinpoint the exact elements tripping Google’s policElementor. • Review Search Console, AdSense policy center messages (if any), and error logs for clues, then translate those findings into a prioritized fix list. • Fine-...

    I need a specialist who can stand up an outbound ViciDial instance and connect it cleanly to Twilio so my customer-support team can start taking and placing calls right away. About 20 agents will log in daily, so the system must be sized and tuned for that load, including concurrent calls, proper carrier failover, and responsive web interfaces. Essential features • Call recording enabled on every leg of the call, saved with logical file names and dates. • Automated call distribution so incoming queues and outbound callbacks are routed evenly across agents, with simple skill-based routing rules. Your work will include installing or hardening ViciBox/Asterisk, configuring Twilio Elastic SIP Trunking, setting up the dial plan, test campaigns, agent log-ins, and showing me wher...

    The Visual Basic program I currently run straight from a USB stick needs to move to the cloud without changing how it behaves. My goal is simple: open the same interface and get the same results, only now over the internet instead of from a pen drive. Preferred environment is a Linux server. I’m open to whichever method makes most sense there—Wine, a lightweight Windows VM, containerisation, or even a web-friendly wrapper—as long as the end-user experience stays identical. Database handling is the one grey area: the app might be using flat files or an old Access database. I’ll need advice on whether we keep that structure, migrate to MySQL/MariaDB, or adopt another engine that plays nicely under Linux. What I’d like from you: • A proposed approach that...

    I need help turning my computer into a true personal assistant. The idea is to install and configure a locally running virtual-assistant desktop application that listens to whatever command I give it—whether that is “set up a meeting for Thursday,” “draft a reply to this email,” or “find and move last month’s invoices into a new folder.” We can build on any solid stack you’re comfortable with: Python, LangChain, Node, Electron, Auto-GPT, or another framework, as long as everything ends up running on my own machine with my keys and data. The assistant should launch like any other desktop app, accept voice or typed input, and return results or carry out the requested action without me opening a terminal window. Deliverables • F...
