...workflow you prefer. The essentials are a clean copy of everything, correct permissions, intact MySQL tables, and a forum that boots on the new IP without throwing errors. Please plan for minimal downtime; I can put the site in maintenance mode while the final sync runs. I’m not yet sure whether the new environment needs extra tuning, so once the forum is online I’d value your quick assessment of Apache/PHP-FPM, MySQL configuration, and vBulletin cache settings. If you spot obvious performance wins, let me know and we can roll them into the same session or a follow-up milestone. Deliverables • Complete transfer of all files, attachments, and the database • Functional vBulletin 4 installation on the Linux target server • DNS or config tweaks so us...
I have an Apache 2-based web application that needs to use Google as its OAuth2 provider. I need a clean, reproducible configuration that lets users sign in with their Google account, then redirects them back to the app with the correct tokens. Here is what I’m looking for: • Guidance inside Google Cloud Console to create the project, consent screen, OAuth2 credentials, and authorised redirect URIs. • The exact Apache configuration (VirtualHost entries, required modules, environment variables, and any RewriteRule or ProxyPass directives) so a fresh server can be brought up and immediately support Google sign-in. • A short README or commented config blocks explaining where to drop client_id, client_secret, scopes, and token endpoints so I can ma...
...baseline I need you to hit: • Full-disk encryption with LUKS configured during provisioning, unlocking only through a self-hosted key management system that lives off–box (no cloud “managed” services, no HSM rental). • The key workflow must survive reboots without ever storing secrets locally and still allow automated patching and recovery. • WordPress itself should sit behind hardened nginx/Apache, with minimum required PHP modules, file-system permissions locked down, and Web Application Firewall rules tuned for the CMS. • Sensitive portions of the MySQL/MariaDB database (user PII, order tables, etc.) plus audit logs must stay encrypted at runtime—either via native TDE, per-column AES functions, or another approach you can just...
...resolving any issues before they reach production. I expect one scheduled maintenance window every month, plus the flexibility to jump in for urgent fixes if something mission-critical breaks between cycles. Clear, concise change logs after each round of work are mandatory so I can track what was updated and why. You should already be comfortable working with CS-Cart’s architecture, PHP, MySQL, NGINX/Apache, and basic server-side tools (SSH, Git, monitoring dashboards). If you also have experience configuring caching layers and CDNs, that’s a bonus. Deliverables are considered complete when: 1. The storefront and admin panel pass all functional tests after updates. 2. Server health metrics (CPU, memory, page load) remain within agreed-upon thresholds. 3. Secu...

...frontend with Python services behind it. I now want everything migrated to my own server and kept healthy long-term. The immediate job is to stand up a fresh production environment, copy the existing codebase, configure all environment variables, storage and database connections, and make the app reachable under my domain without losing any current features. I’m open to the exact mix of Nginx, Apache or a Node.js layer as long as it fits the React/ build; you can recommend the best approach once you see the code. Deliverables • Clean deployment of the application on my server, functioning exactly like the current live instance • Automated build / CI-CD pipeline (GitHub Actions or similar) for seamless future releases • Documentation covering setup, roll...
...specialist to take over continuous protection duties. The priority is to keep the box clean, locked down, and fully recoverable at all times, so I’m commissioning an ongoing monitoring and troubleshooting arrangement rather than a one-off audit. Scope of work • Start with a comprehensive security audit: scan for existing malware, review logs, check permissions, and verify that all core services (Apache/Nginx, Exim, MySQL, SSH) follow current best practices. • Implement layered defences aimed at the three concerns I flagged—malware detection & removal, unauthorized-access prevention, and data encryption/protection. Typical tools might include CSF/LFD, ModSecurity rulesets, hardened SSH policies, ClamAV or Imunify360, and full-disk or at-rest encrypti...
...can reach it through the domain already sitting in my GoDaddy account. Here is what I need from you: • Move the current project from local to the VPS (SSH, Git or any secure method you prefer). • Install the required Node.js version and production dependencies. • Set up a process manager such as PM2 to keep the app alive and auto-restart on reboot. • Configure a reverse-proxy (Nginx or Apache) so the site serves over port 80/443. • Update or create the necessary A/AAAA and CNAME records; I marked “Yes” for DNS help because I want the domain to resolve cleanly worldwide. • Apply an SSL certificate (Let’s Encrypt is fine) and make sure HTTP automatically redirects to HTTPS. • Hand over concise notes so I can repea...

...server. The core of the job is server setup and ongoing management: securing the OS, installing the full web stack, and making sure everything runs smoothly day-to-day. The server will host multiple sites, so I need virtual-host configuration, SSL (Let’s Encrypt) automation, log rotation, routine backups, and monitoring in place. I have not committed to a particular web engine yet; if you feel Apache, Nginx, or Lighttpd would serve my traffic profile better, present your reasoning and we’ll proceed with the best fit. Deliverables • Hardened Ubuntu (latest LTS) with all updates applied • Chosen web server installed, tuned, and benchmarked • Firewall & fail2ban configured, SSH locked down • Virtual hosts and SSL certificates issued & ...
...During traffic spikes the endpoint suddenly answers with HTTP 429 instead of the expected 200, so the calling service retries and eventually fails. The code itself has no limiter, which makes me suspect a server-level restriction that I’m not yet aware of. Your task is to trace the component issuing the 429s and tune or disable the rule so the webhook survives peak loads. It could be an Nginx/Apache rate-limit, ModSecurity, fail2ban, iptables, or something similar—I’m open to whatever you find. Acceptance criteria • Pinpoint the exact service or module returning 429 • Apply and document a configuration fix (or clean, minimal code patch if that proves necessary) • Stress-test the endpoint and demonstrate consistent 200 responses under load ...
...& after using tools like GTmetrix, Google PageSpeed Insights, Pingdom Clear communication and step-by-step summary of changes made No use of nulled plugins or unsafe methods Work must not break the site design/functionality Nice to have: Experience with caching plugins (WP Rocket, W3 Total Cache, etc.) Experience with image optimization tools (Smush, ShortPixel, Imagify) Familiarity with Apache/NGINX and PHP version optimization Budget & Timeline: Budget: $50–$200 Timeline: 3–5 days after project start Please include in your proposal: Your estimated time to complete the job Tools & methods you plan to use Before/after example from a previous WordPress speed optimization project (screenshot or link) Thank you!...
I run a Linux VPS on Bluehost that powers a handful of PHP web applications backed by MySQL. I’m ready to hand off the day-to-day technical work so I can focus on the product, but I need everything kept running smoothly right away. You’ll receive full Control Panel access (no root SSH), and from there I expect three core services: • Server maintenance – keep the OS, Apache, PHP versions and security patches up to date, monitor logs and resource usage, and restart services if they stall. • Database management – schedule automated MySQL backups, tune indexes for performance, and restore data quickly if ever required. • Code deployment – pull the latest code from the Git repository, run any composer / npm steps, update environment vari...

...PDF file that is equally rich in formatting. The purpose is to generate a clear, detailed comparison report that tells me where wording diverges, which tables differ, and whether any images or captions have changed. You are free to choose the language and libraries you find most efficient (Python with python-docx, BeautifulSoup4, pdfminer or PyPDF2 is perfectly fine; a C# or Java solution using Apache POI, iText, etc. is equally acceptable). What matters is that the script: • Extracts all textual segments in reading order from both sources, even when they are embedded in tables, text boxes or figure captions. • Ignores purely stylistic discrepancies unless they influence meaning. • Outputs a human-readable report—Markdown, HTML, or an annotated DOCX are...

...“elevation” on a server still running version 86 and need a skilled admin to handle the optimization work. The core goal is server-side tuning—what I’m calling “Upgradation A”—to squeeze better performance out of the stack before any further updates go live. Here’s what I expect from you: • Analyse the current v86 environment, pinpoint bottlenecks and unsafe defaults. • Apply optimisation tweaks (Apache/NGINX, PHP, MySQL, caching, resource limits) that deliver measurable gains without breaking existing sites or email. • Document each change so I can reproduce or roll back if required.

...lands on the DigitalOcean Droplet. After the data is in place, you’ll configure the Droplet to match the original PHP and Apache versions, set correct virtual-host rules, and wire up environment variables so the app boots without code changes. Security is non-negotiable. The move must incorporate a valid SSL certificate—Let’s Encrypt is fine—and enable database-at-rest encryption. If you prefer full-disk encryption at Droplet level, note that in your approach. Either way, I expect encrypted data on disk and encrypted traffic in transit. Key deliverables: • Successful MySQL export from Hostinger and import to DigitalOcean • Droplet configured with matching PHP/Apache settings and working vHosts • SSL certificate installed and f...
I have built a small portfolio site in PHP, HTML & CSS that runs on an Apache server and stores its content in a MySQL database. Right now, every public link still carries query-strings—e.g. mydomain/ I want this turned into true, SEO-friendly paths–e.g. mydomain/image/6/My-Image-Title I've created a database field to store the [slug] value that will be used as My-Image-Title In addition, I’d like all remaining .php and .html extensions stripped cleanly, so visitors (and search engines) never see a file suffix. What I need from you is a set of RewriteRule and RewriteCond directives—regular-expression based, ready to drop into my .htaccess file—that: 1. Translate the current query-string format to the clean structures shown abov...
