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.

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 ...

My WordPress site is currently marked as “compromised” in Google Ads, blocking me from launching a new campaign. I have already updated all plugins and themes and forced HTTPS I need a security-savvy WordPress specialist to: • Pinpoint and remove any malicious code, malware, or suspicious files still hiding in the installation (core, themes, uploads, database). • Close the loophole that let the intrusion happen in the first place and harden the site (secure file permissions, firewall/Security plugin configuration, login protection, etc.). • Generate a concise cleanup log I can keep on file. • Handle or guide me through the Google Ads resubmission so the “compromised site” warning is cleared and the campaign can go live.

We are seeking a skilled freelancer to migrate our website from SiteGround to Hostinger. The ideal candidate will have experience in website migration and be able to ensure a smooth transition with minimal downtime. Responsibilities include transferring all website files, databases, and settings to the new hosting platform. Attention to detail and excellent communication skills are essential.

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’m moving my entire WooCommerce store to Shopify and need an expert who can handle the migration end-to-end without compromising speed, data integrity, or security. Every customer record, review, product (with variants), image, and order history must arrive in Shopify exactly as it currently sits in WooCommerce—no broken links, no missing metadata, and absolutely no malicious code sneaking in during the transfer. Once the data is in place, I’d like you to install and set up a paid theme from the official Shopify store. Because I’m looking for a brand-new design rather than mirroring the old site, you’ll have creative freedom to configure that theme so it delivers a noticeably better user experience and a modern, visually appealing storefront. Clean, lightwei...

I need GenieACS installed, secured, and fully tuned to manage Airtel Xstream routers in production. The deployment must let me: • Register and remotely manage devices • Push firmware upgrades without manual intervention • Monitor performance metrics in real time • Apply custom IP pools, VLAN tagging, and QoS rules directly from the ACS interface You are free to choose the operating system and database you are most comfortable with; just document every step clearly so I can reproduce it on another machine. A clean web UI, working API calls, and successful provisioning of at least one Airtel Xstream unit will serve as acceptance criteria. Cloud or on-prem hosting is fine as long as latency remains low and security best practices (TLS, strong credentials, firewa...

Deliverables • Full scan report showing the location of each malicious file or code fragment discovered and the action taken to remove it. • Clean, functioning site with no residual malware signatures or black-list flags. • Verification that Google, Bing and Yahoo have successfully re-indexed all pages (Search Console a...

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 ...

I want a seasoned security professional to probe my site from every angle and show me—plainly—where a hacker would slip in. My main worry is outright breaches, not just compliance check-boxes, and at the moment I only have the usual basic plugins and a standard SSL certificate in place.

Feel free to bring out Burp Suite, OWASP ZAP, Nikto, or whatever toolset you trust; I’m interested in real-world exploitability, not generic scanner output. Please deliver: • A concise report detailing each weakness, its risk level, and clear remediation steps • A prioritised action plan I c...
