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...

Urgent: PrestaShop 1.7.6.5 Malware Removal (Credit Card Skimmer), Security Hardening, Upgrade to PrestaShop 9.x & Migration to secure hosting provider. Project Description: My PrestaShop store (1.7.6.5, ~600 products, low traffic) has been compromised. The site is infected with a “digital skimmer” (a credit card skimmer / Magecart‑type malware) that redirects customers during checkout to a fraudulent payment page. Card payments are disabled, and the shop is in maintenance mode to prevent further harm. The website loads extremely slowly when not in maintenance mode, indicating malicious scripts are present. I need a complete, permanent solution. You must prove you have successfully completed similar PrestaShop security work before (please provide references or portfolio l...

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’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’ve just finished moving my site to a new host and now need the domain traffic switched over smoothly. I already have full access to the DNS management console, so you can dive straight in once we agree on the exact records to touch. Your task is to identify every entry that must change—most likely the root A record and the www CNAME—and update them so the domain resolves to the new server. I’d like the cut-over handled with minimal downtime, which means adjusting TTLs, scheduling the update at a quiet time, and confirming propagation once the edits are saved. Please double-check that SSL, email, and any sub-domains continue to work afterward. Deliverables • Updated zone file pointing to the new host • Brief confirmation report listing the records...

I run my workload on a single Compute Engine instance and I’m urgently looking to tighten security after a recent unauthorized-access event. The immediate priorities are: • Lock down the instance: review and update firewall rules, service accounts, IAM roles, OS-level settings, and any exposed ports. I expect clear recommendations (e.g., Cloud Armor policies, VPC Firewall tweaks, OS patching) and implementation where feasible. • Trace the breach: pull the relevant Cloud Logging records, VPC flow logs, and any SSH / RDP audit data to build a timeline showing when the intrusion occurred, the source IPs, and actions performed. Deliver the raw export plus a concise report so I can hand it to management. • Prevent recurrence: enable or improve ongoing monitoring—Se...

I need a production-ready crypto exchange site that lets users trade on a live spot market with Bitcoin, Ethereum, Ripple and USDT from day one, with the option to add more pairs later. Real-time order books, depth charts, trade history and WebSocket price feeds should feel as fast as the major exchanges. Security is the main priority. The build must ship with strong account protection (2FA, email/SMS verification), cold-wallet segregation for the majority of funds, hot-wallet limits, and an architecture that can absorb DDoS spikes without downtime. Please plan for regular penetration testing and clear audit logs. A clean React (or Vue) front-end talking to a Node.js, Go or comparable back-end is preferred, but I’m open to other proven stacks if you can demonstrate equal or better ...

My WooCommerce-based e-commerce store has suffered repeated security breaches and frustrating periods of downtime since it was first launched. Each incident has cost additional money in “fixes” and paid add-ons that never solved the root problem. I need the site rebuilt correctly, with security and long-term stability engineered in from the start—not patched on later. Scope of work • Audit the existing WordPress / WooCommerce installation, themes and plugins to locate back doors, vulnerable code, or configuration errors. • Rebuild or replace the current theme and plugin stack with lean, well-supported alternatives, keeping functionality identical or better while eliminating unnecessary paid extensions. • Implement solid security hardening: firewall r...

I have a set of documents whose fields need to live in a MySQL database. Your task is to create a well-structured PHP script that does two things: 1. Forms for receiving data, on submission sanitize every field, and insert the data into MySQL using prepared statements so nothing slips past standard security checks. 2.

A recent malware incident on our server has left several database files renamed with a “.p2k” extension and rendered unreadable. These files hold mission-critical operational data and, unfortunately, there are no usable backups to fall back on.
