I am preparing to release the final payment to my current development team and want absolute confidence that the code base is clean, secure, and free of anything that could be used against me later. Your mission is to perform an independent, end-to-end audit that zeroes in on code quality and security, followed by a roadmap for reliable, Texas-based support. Scope of the audit • Code review and best practices – confirm style consistency, proper version control use, and absence of hard-coded secrets or hidden backdoors. • Security vulnerabilities – static and dynamic analysis, penetration testing where appropriate, and a clear risk matrix that prioritizes critical fixes. • Performance health – benchmark speed and efficiency, stress-test error han...

My HostGator shared-hosting account has started to run out of space and I suspect there may also be a collection of suspicious or simply unwanted files scattered across the server. I’m not yet certain which directories, databases, so the first step will be a careful audit of everything inside cPanel—public_html and outside of it (some websites /domain that are no longer used were located there), MySQL databases, backups, and logs. Here’s the flow I have in mind: • Initial scan: you connect via cPanel / FTP / phpMyAdmin, map out disk usage, and flag any files, plugins, backups, or database tables that look redundant, outdated, or potentially malicious. • Cleanup plan: present a short report outlining what can be safely removed or archived, with special attent...

My AI-driven web app () already sits on SiteGround, but their shared plans can’t run the Node/Express server that powers my OpenAI logic. I now need a hosting move and full deployment so the backend finally runs live. What I’m looking for • Help me choose and provision a host that natively supports Node.js with full shell access. I’m open to any reputable provider—managed VPS, bare-metal, or a modern PaaS—as long as it gives me the control a typical Express + OpenAI setup demands. • Secure server build-out: firewall hardening, SSL/TLS, env vars for OpenAI keys, and the usual rate-limit protections. • Deployment of my existing repository, install dependencies, and configure the production process manager (pm2, forever, or similar). &bull...

Please check for issues such as: SQL injection XSS Login/security weaknesses File upload vulnerabilities Admin panel exposure WordPress/plugin issues, if applicable Server/header security SSL/HTTPS configuration Malware/backdoor checks General vulnerability report I need a written report showing: What vulnerabilities were found Risk level: low / medium / high / critical Proof of issue without damaging the site Clear steps to fix each issue Important: No destructive testing, no spam, no DDoS, no data deletion, and no testing outside my domain. Skills required: Ethical Hacking, Penetration Testing, Web...

My long-running WordPress site () has been reskinned so many times that the codebase is now a patchwork of old themes, unused folders, conflicting plugins, and the occasional bit of malware. I want to start over on a brand-new server, yet preserve the public-facing look and feel that visitors already know. Here’s the outcome I’m after: an exact visual clone—same theme, menus, page structure, and styling—but built from a clean, current WordPress install. The new build must migrate all website content, blog posts, media, and the SEO settings that rank us in search today. While most existing functionality stays, you’ll identify and remove problematic or duplicate plugins, suggest modern replacements where needed, and can add new features that improve speed or se...

I’m looking for a tech-savvy professional who can diagnose and resolve the slow internet speeds on my network. The issue isn’t a full outage—pages eventually load, but streaming, video calls, and large downloads crawl. I’ve confirmed the problem persists across multiple devices, so it appears to be network-wide. Here’s what I need from you: • Run a structured troubleshooting session via remote tools (e.g., Zoom, TeamViewer, or your preferred platform). • Review my modem and router settings, firmware version, and channel/bandwidth configuration. • Guide me through speed tests and analyze the results to pinpoint bottlenecks—ISP, hardware, cabling, or Wi-Fi congestion. • Recommend and implement fixes: optimal DNS settings, QoS twe...

I have a web-based application almost ready to roll out; the only item still missing is a set of secure database access links that my front-end can call for standard user-login sessions. I need those links built, verified, and handed over together with any connection strings or tokens that go with them so that end-users can sign in without ever touching elevated credentials. What I expect from you • Create the actual database access URLs (or connection strings) configured strictly for user-level privileges. • Confirm they function end-to-end by testing a sample login flow against the live site. • Supply a short note or README explaining where each link should be placed in the codebase and how to rotate or revoke it if required. If you have experience hardening conn...

My WordPress site was hit by malware very recently, so the first task is to track down and remove every malicious file, script, or database entry without taking the site offline. Once the infection is gone, I need the entire installation hardened against future attacks—core, theme, and plugin updates, a properly configured Web Application Firewall, brute-force login protection, real-time scanning, and any other best-practice measures you consider essential. Turnaround is critical; I’d like actionable progress the same day we start and a fully secured site as soon as possible. Acceptance criteria: • Zero malware detected by Wordfence, Sucuri, or equivalent scanners • Site operates normally with no design or functionality loss • Security tools and firewall ...

Several of my e-commerce sites were handed back to me in a broken state after the last developer left. Pages may load, but the core booking and checkout journeys are unreliable: customers can’t complete a booking and I can’t create manual orders in the back-end. Broken links, random design glitches and occasional 500 errors are also showing up. The immediate goal is simple—make every site fully functional for both shoppers and administrators—yet the work will probably start with a clean audit so we know exactly what was changed and what still complies with the original platform standards. Once the problem list is clear, each issue needs to be fixed, tested and documented so the same failure doesn’t resurface with the next update. Please be comfortable diggin...

I am looking to do a full re-write of our existing web application. Currently is it running an older version of Extjs, php, and html5 viewer. I would like to explore options to either upgrade existing stack or completely move to a newer more modern stack. Security and HIPPA aware audit logging is mandatory Maintaining existing features and functions are a must. Increased security. Long term ease of updating and maintenance important as well. Cosmetic updates to UI as well from older extjs to a UI with a clean, clinical-yet-modern aesthetic. (see current and sample(idea) for new UI. Current system has: User administration - Users - typical with option to allow/restrict functions Groups - To add users to g...

I’m looking for a developer who can completely strip out every Adsterra-related snippet from both the server files and the on-page source code across multiple websites hosted on my server. Scope of work: • Locate and delete all Adsterra scripts, iframes, or tracking calls in server-side files (PHP, JS, HTML, config, etc.). • Clean the corresponding front-end pages so no residual Adsterra tags remain. • Verify that each cleaned site loads normally and that no broken layouts, console errors, or missing assets appear after removal. • Provide a concise report listing the directories and pages you touched plus a final confirmation that the codebase is Adsterra-free. Please work carefully—these are live sites—and keep downtime to an absolute minimum.

I’m getting a surge of requests that originate from headless browsers and my current behavioural-analysis script just isn’t keeping them out. I need a reliable solution that can: • Detect headless visitors consistently—whether they slip in through altered user-agents or by mimicking normal browsing patterns. • Automatically divert anything flagged as headless to a separate page (or lightweight holding page if you recommend building a fresh one). Legitimate users must continue to browse uninterrupted. You are free to combine JavaScript fingerprinting, server-side checks, bot-score APIs, or any other proven technique, as long as it keeps false positives low. Clear, well-commented code and a short read-me on how to tweak thresholds are essential so I can mainta...

I’m about to launch our paywall on and I need an expert to confirm that every subscription-related interaction behaves exactly as designed while we’re still on the staging article Here is what I must see working before launch: Specifically: 1. Once a user pays, will future articles be automatically unlocked for them? 2. How does the login flow work for paying users? 3. What happens after 365 days — is there an automatic renewal, or does it need to be done manually?

I’m preparing to flip the switch on the new paywall for and need an expert to be sure every step behaves exactly as intended. Specifically: 1. Once a user pays, will future articles be automatically unlocked for them? 2. How does the login flow work for paying users? 3. What happens after 365 days — is there an automatic renewal, or does it need to be done manually? You’ll work our staging article ()

My store was operating smoothly until a few hours ago; now it refuses to load at all. The browser shows only a vague error with no clear explanation, and I haven’t touched the code, themes, or plugins recently. I need someone who can jump in immediately, identify the root cause, and restore full access so customers can shop again without interruption. What I expect from you: • Rapid investigation of the server logs, database connection, and application files • Clear identification of the fault—whether it lies in hosting configuration, corrupted files, or something else entirely • A clean fix that brings the site back online and keeps checkout functionality intact • A brief summary of the problem and the steps you took, so I can avoid the same issue ...
