Our staff and students cannot open a brand-new educational website when they are connected to the school’s office Wi-Fi. Every device—laptops, tablets and phones—shows the same “error connection loading” message, so the problem is clearly network-side rather than user-side. The site works perfectly once we switch to mobile data or an external network.
I need a network specialist who can quickly diagnose why this single educational domain is being blocked or timing out inside our LAN/WLAN and apply a clean, permanent fix. Whether it involves firewall rules, DNS filtering, SSL inspection, proxy settings or VLAN segmentation, I’m looking for clear root-cause identification and a working solution that lets the page load normally on all devices while keeping our existing security policies intact.
Deliverables:
• Identify the exact point of failure (router, firewall, DNS, content filter, etc.).
• Implement or guide us through the corrective change.
• Provide a short write-up so we can document the adjustment for future reference.
If remote access to our controller or firewall is required, I can arrange that immediately. Let me know your preferred troubleshooting tools and an estimated timeframe, and we’ll get started right away.

We're a small enterprise SaaS company serving K-12 schools with a Student Information System (SIS) platform. Our infrastructure is self-hosted (on-prem/colo) and supports a multi-tenant production environment that schools rely on daily. We're a .NET shop (ASP.NET, IIS, Windows Server, MS SQL Server multi-tenant database).
We're looking for a network and infrastructure expert — individual, small team, or agency — to serve as our ongoing technical authority for our core hardware/network stack, and to guide our onsite engineer through implementation, upgrades, and day-to-day best practices.
## Our Current Environment
- **Firewall/WAF:** Fortiweb (Web Application Firewall)
- **Switching:** Fortinet switches
- **Compute:** 2x Hyper-V servers (host our virtualized Windows Server environment)
- **Storage:** HPE Alletra storage array
- **Backup/DR:** Veeam (backup and restoration)
- **Application stack:** ASP.NET, IIS, Windows Server, MS SQL Server (multi-tenant)
We have an onsite engineer who can execute physical/hands-on work under your direction — you don't need to be local, but you do need to be able to produce clear, actionable guidance and documentation they can follow.
## Scope of Work
**Phase 1 — Assessment & Documentation**
- Conduct a full audit of our current network and hardware environment
- Produce a detailed network/hardware map (topology diagram, IP schema, VLANs, firewall rules/policies, switch configs, storage layout, backup jobs/retention, and how it all interconnects)
- Document current-state configuration for Fortiweb, Fortinet switches, Hyper-V hosts, HPE Alletra storage, and Veeam backup jobs
- Identify single points of failure, security gaps, and configuration risks
**Phase 2 — Recommendations**
- Provide a prioritized list of improvements: security hardening, redundancy/high availability, performance, and scalability
- Recommend capacity planning for growth (storage, compute, bandwidth) given we run a multi-tenant SaaS workload
- Advise on backup/DR strategy adequacy (RPO/RTO) using our existing Veeam setup
- Flag any end-of-life/end-of-support hardware or firmware concerns
**Phase 3 — Execution & Ongoing Support**
- Guide (and where appropriate, remotely execute alongside) our onsite engineer on approved upgrade/improvement projects
- Available for ongoing advisory support as we scale (new hardware procurement guidance, configuration changes, troubleshooting escalations)
- Be a resource we can reach out to for architecture decisions as the business grows
## What We're Looking For
- Proven hands-on expertise with **Fortinet products** (FortiWeb WAF and FortiSwitch, FortiGate/FortiOS knowledge a plus)
- Strong experience with **Microsoft Hyper-V** virtualization (host configuration, clustering/HA, performance tuning)
- Experience with **HPE Alletra** (or comparable enterprise SAN/storage platforms — HPE Nimble, 3PAR experience relevant too)
- Deep familiarity with **Veeam Backup & Replication** (backup strategy, job configuration, restoration testing, DR planning)
- Solid understanding of enterprise networking fundamentals: VLANs, routing, firewall policy design, network segmentation, security best practices
- Experience working with environments running **Windows Server, IIS, and MS SQL Server** (understanding how infrastructure decisions affect a .NET/SQL Server application stack is a big plus)
- Experience supporting SaaS or other environments where uptime and data integrity are business-critical
- Comfortable creating clear, professional documentation (network diagrams, runbooks, config docs) that a less-senior onsite engineer can follow
- Strong communication skills — able to explain technical tradeoffs to a non-network-specialist stakeholder
## Nice to Have
- Experience in education technology (EdTech) or other regulated/compliance-sensitive SaaS environments
- Relevant certifications (Fortinet NSE, VMware/Hyper-V, HPE storage certifications, Veeam VMCE)
- Prior experience as a fractional/virtual infrastructure lead for a small company
## Engagement Details
- **Engagement type:** Project-based to start (assessment + documentation), with strong potential for an ongoing retainer/advisory relationship
- **Team size:** Open to individual consultants, small teams, or agencies — please indicate which you are
- **Remote:** Yes — work will be guided remotely, executed onsite by our engineer, with occasional coordination calls
- **Timeline:** Looking to begin the assessment phase as soon as possible
## To Apply, Please Include
- Relevant experience with Fortinet, Hyper-V, HPE storage, and Veeam specifically
- An example of network documentation or an infrastructure assessment you've produced (redacted is fine)
- Whether you're applying as an individual, team, or agency, and your general availability
- Your proposed approach to Phase 1 (assessment) and a rough estimate of time/cost for it

We are a boutique financial consultancy firm managing high-net-worth corporate portfolios and institutional investments. Our digital presence must reflect the premium, authoritative nature of our services. We are currently undertaking a comprehensive website redesign and are actively seeking an elite WordPress developer to spearhead the technical execution of this project.
Our primary objective is to transition away from our outdated digital footprint and build a highly secure, modern WordPress website that instills immediate trust and makes it seamless for corporate clients to request private consultations.
The Role:
We are not looking for a basic template installation. We need a seasoned web developer who understands how to build a bespoke, scalable architecture from the ground up.

Consultation Funnel Integration: Implement premium landing page web design for our primary contact funnels to maximize corporate lead generation.
Security & Hardening: Execute top-tier security protocols. As a financial firm, this custom WordPress environment requires strict SSL configuration, database prefix updates, customized login paths, and robust firewall deployment.
Backend Usability: Design a heavily streamlined, intuitive backend interface so our non-technical financial staff can publish weekly market insights effortlessly without navigating complex builder menus.
Ideal Candidate Profile:
Proven track record as a senior WordPress developer and web developer, specifically working with corporate, legal, or financial brands.
Absolute mastery of Elementor Pro, dynamic tags, and custom loops.
Deep understanding of responsive design frameworks and advanced CSS/HTML.
Strong capabilities in technical SEO optimization and core web vitals, ensuring the new WordPress website loads instantly to prevent bounce rates.
Ability to operate as a full stack web developer when custom PHP or database troubleshooting is required.
To Apply:
Please submit your proposal with a brief outline of your approach to securing a financial website. To ensure you have read this brief in its entirety, please begin your cover letter with the exact phrase: "CORPORATE WEALTH". Please also include links to 3 live corporate or B2B portfolio sites you have built.

I keep hitting the Cloudflare 1015 “rate-limited” error across every site I maintain, including our developer instances, and I need a clean, lasting fix that does NOT rely on rotating proxies or other work-arounds that might break later.
Context
• CDN in use: Cloudflare on all domains.
• The same error appears on production and developer environments; I have not pinpointed any regional pattern yet.
• I want the root cause identified and eliminated so traffic flows normally for every visitor, everywhere.
Deliverable
A step-by-step solution (configuration changes, code tweaks, or Cloudflare rule adjustments) that you implement and verify on one site, then document so I can replicate it on the rest. The fix must survive cache purges, deploys, and Cloudflare updates without needing proxy swaps.
Acceptance Criteria
1. No 1015 responses for 48 hours under normal load, confirmed via logs and real-time testing.
2. No degradation in performance, security, or SEO.
3. Clear rollback instructions and a concise report of what was changed.
If you’ve already cracked this problem before, tell me how long it took and what tools you’ll bring—Cloudflare Rate Limiting settings, Workers, firewall rules, server-side throttling adjustments, etc.—so we can move quickly.

Success in this role requires excellent analytical and troubleshooting skills, strong written and verbal communication, and the ability to explain technical concepts clearly to both technical and non-technical stakeholders.

I need a complete, pre-recorded training session that equips intermediate-level professionals with practical, immediately applicable skills in Network Security, Ethical Hacking, and Data Protection. The session must be delivered as a high-quality video with slides, smoothly blending screen-recorded demonstrations and a narrated slide deck so viewers can follow along step by step.
Content depth should assume the audience already understands basic terminology yet still needs guidance on real-world implementation—think firewall hardening, vulnerability scanning workflows, exploit demonstration, and best-practice data-handling procedures. Wherever possible, showcase widely used tools such as Wireshark, Nmap, Metasploit, Burp Suite, and OWASP resources to ground the theory in hands-on practice.
I will handle distribution internally, so please ensure you own or can transfer all usage rights for both the video and slide assets.
Deliverables (attach in a single hand-over package):
• One MP4 (1080p or higher) containing the full “video with slides” lecture
• The matching slide deck in PowerPoint or PDF for reference
• Any sample scripts, lab files, or configuration snippets used during demonstrations
Acceptance will be based on:
• Clear, professional audio and visuals throughout
• Logical flow that covers Network Security → Ethical Hacking → Data Protection without large knowledge gaps
• Practical walkthroughs that an intermediate learner can replicate on his or her own lab environment
Let me know your estimated runtime and turnaround time, and feel free to suggest minor outline tweaks if it helps sharpen the learning outcome.

We are optimizing a high-concurrency web application frontend and data pipeline interacting with complex REST and GraphQL endpoints. While 95% of our system architecture is complete, we have hit a major roadblock regarding request handling under heavy load, specific cloud infrastructure responses, and session state synchronization.
We need a backend and network traffic specialist who deeply understands modern web application architectures, cloud caching layers, API Gateway behavior, and browser-vs-script request execution differences.
---
### **Key Technical Challenges to Resolve:**
1. Data Latency & Caching Layers:
- Investigating update propagation delays between GraphQL search queries and REST detail endpoints during high-frequency data changes. Analyzing how caching layers (such as CDN/edge or intermediate caches) affect data freshness.
2. Automated vs. Browser Request Execution:
- Troubleshooting a scenario where specific state-updating HTTP methods (`PUT`) succeed seamlessly when executed natively inside a browser context, but encounter edge gateway/firewall blocks when automated via custom HTTP clients, despite identical payload and authentication structure.
3. Inventory State & Concurrency Control:
- Analyzing backend race conditions, TTL-based soft reserves, and inventory count synchronization models under high request volumes.
4. Lifecycle & Persistence Management:
- Reviewing entity creation lifecycles, database persistence rules, and automatic expiration windows for uncommitted workflow tokens.
---
### **Ideal Candidate Profile:**
- Deep expertise in AWS serverless infrastructure, API Gateway configuration, and advanced request routing/security policies.
- Advanced proficiency in inspecting complex browser network traffic, session header requirements, and programmatic client integration.
- Practical, hands-on experience solving complex networking and concurrency bottlenecks in high-load web systems.
Please share your background with network analysis, API optimization, and similar architectural troubleshooting when applying.

I’m launching a proprietary-funding firm and need a full website built from the ground up. Think FTMO or FundedNext for overall flow, but on a smaller scale and powered by a Match-Trader white-label backend.
Core goals
• Modern, sleek look that immediately inspires trust.
• Seamless client journey: landing page → plan selection → quick sign-up → account creation on Match-Trader.
• Self-service client area where traders can view balances, open challenges, and manage personal details.
• Embedded checkout that handles card and alternative payments, routes funds to the correct plan, and triggers account provisioning automatically.
What I’ll hand over
• Domain name and Match-Trader credentials.
• Brand colours, logo, and copy draft.
What I need from you
• UX/UI design (responsive, desktop & mobile).
• Front-end build (React, Vue, or another modern stack is fine) and CMS setup so I can tweak text and pricing.
• Back-end or middleware that calls Match-Trader’s API to create, suspend, or upgrade accounts.
• Payment gateway integration (Stripe preferred, open to others).
• Hosting configuration and deployment on my chosen VPS or a managed platform.
• Basic on-page SEO and security hardening (SSL, firewall rules, anti-bot on forms).
Acceptance criteria
1. New user can purchase a challenge, complete checkout, and receive platform credentials automatically within minutes.
2. Existing user can log in, see account metrics pulled live from Match-Trader, and download monthly statements.
3. Site scores 90+ on Google PageSpeed for both mobile and desktop.
4. All pages match approved Figma mock-ups pixel-perfectly.
If you have shipped a trading, fintech, or SaaS site before, that’s a plus—send over links. I’m ready to start right away and will be active in providing feedback throughout the build.

We are looking for an experienced WordPress developer or small web-development agency to migrate an existing company website from a custom-built C# system to WordPress.
The company manufactures industrial digital printing machinery. The website includes product and machine pages, application pages, technical information, news, videos, downloadable brochures, contact forms and multilingual content.
This is not a simple template installation. We need a complete, professional WordPress system that is fast, secure, easy for our team to manage and properly prepared for SEO and AI search visibility.
The current website address will be shared with shortlisted candidates.
### Project Objectives
The selected developer will be responsible for:
* Auditing the existing website and its content
* Creating a complete inventory of existing URLs
* Migrating all relevant pages, content, images, videos and downloadable files
* Rebuilding the website in WordPress
* Preserving existing SEO value and rankings
* Creating a fast, mobile-responsive and technically clean website
* Building an easy-to-manage backend for our internal team
* Collaborating with our graphic designer on the visual design
* Preparing the complete website for launch
### Required WordPress Structure
The website should use structured content rather than treating everything as a basic page.
We expect appropriate WordPress content structures for areas such as:
* Machines and products
* Applications
* Printing technologies
* Industries
* Case studies and installations
* News and exhibitions
* Technical articles
* Videos
* Brochures and downloads
* Company locations and contact information
Machine pages should support structured information such as:
* Machine name
* Description
* Printing width
* Production speed
* Printhead technology
* Ink type
* Compatible materials
* Applications
* Technical specifications
* Images
* Videos
* Brochures
* Related machines and technologies
* Inquiry forms
The system should make it easy for us to add new machines, applications and articles without rebuilding pages manually.
### Design and Development Requirements
* Custom, professional WordPress implementation
* Collaboration with our graphic designer
* Responsive design for desktop, tablet and mobile
* Clean and lightweight frontend
* Reusable page sections or blocks
* Server-rendered, crawlable content
* Minimal unnecessary JavaScript
* No cheap multipurpose theme
* No excessive plugin usage
* No dependence on unsupported or pirated plugins
* Easy content management for non-technical users
* Staging and production environments
We prefer Gutenberg or another clean and maintainable WordPress editing system. We do not want a slow website overloaded with page-builder plugins.
### Multilingual Requirements
The existing website contains multiple languages. The new WordPress system must properly support multilingual content.
This includes:
* Separate URLs for each language
* Correct hreflang implementation
* Language-specific menus
* Language-specific metadata
* Correct canonical tags
* Easy translation management
* No automatic IP-based redirects that prevent crawling
* Proper multilingual XML sitemaps
Please explain which multilingual solution you recommend and why.
### SEO Migration Requirements
SEO preservation is a critical part of this project.
The developer must:
* Crawl and audit the existing website before migration
* Create a complete old-to-new URL mapping
* Preserve important URL structures where practical
* Implement individual 301 redirects
* Avoid redirecting all old pages to the homepage
* Preserve or improve page titles and meta descriptions
* Implement canonical tags
* Configure XML sitemaps
* Configure robots.txt
* Implement breadcrumbs
* Add appropriate structured data and JSON-LD
* Optimize heading structure
* Preserve image alt text where available
* Prevent duplicate or thin pages
* Configure Google Search Console
* Configure Google Analytics
* Test redirects and crawlability before launch
* Monitor indexing and errors after launch
Experience with multilingual SEO migrations is strongly preferred.
### SEO and AI Search Readiness
The new website should be technically prepared for traditional search engines and generative search platforms.
Important information must be available directly in the HTML and should not exist only inside images, animations or PDF brochures.
The website should include appropriate structured data for:
Relevant legitimate search crawlers should not be accidentally blocked.
### Performance Requirements
The completed website should be optimized for:
* Fast loading times
* Core Web Vitals
* Mobile performance
* Image compression and next-generation image formats
* Lazy loading where appropriate
* Full-page caching
* Browser caching
* CDN integration
* Database optimization
* Minimal plugin and script bloat
Please include examples of websites you have built that perform well in Google PageSpeed Insights or Core Web Vitals.
### Hosting, Security and Maintenance
The developer should recommend and configure an appropriate managed WordPress hosting environment.
The setup should include:
* SSL
* CDN
* Web application firewall
* Daily backups
* Off-site backup storage
* Two-factor authentication
* Limited administrator access
* Staging environment
* Malware and security monitoring
* Update and rollback procedures
* Spam protection for forms
* Uptime monitoring
Please also provide an optional ongoing maintenance proposal after launch.
### Forms and Tracking
The website will require professional inquiry forms, including product-specific inquiries.
Forms should:
* Send reliable email notifications
* Store submissions securely
* Identify which machine or application generated the inquiry
* Include spam protection
* Support conversion tracking
* Be prepared for future CRM integration
### Expected Deliverables
The final delivery must include:
* Fully functional WordPress website
* Migrated and organized content
* Responsive frontend
* Multilingual setup
* SEO migration and redirect implementation
* Performance optimization
* Security configuration
* Analytics and Search Console setup
* Form configuration and testing
* Staging and production setup
* Administrator documentation
* Training session for our team
* Backup and rollback plan
* Post-launch support period
* Full transfer of code, licenses, credentials and ownership
The website will not be considered complete until the important pages, forms, downloads, languages, redirects and tracking systems have been tested.
### Required Experience
Applicants should have proven experience with:
* WordPress development
* Custom WordPress themes or block development
* Custom post types and structured content
* Multilingual WordPress websites
* SEO-sensitive website migrations
* 301 redirect mapping
* Technical SEO
* Structured data
* Core Web Vitals
* Website security
* Managed WordPress hosting
* Migrating websites from custom CMS platforms
Industrial, manufacturing, engineering or B2B website experience is a major advantage.
### Application Instructions
Please answer the following questions in your proposal:
1. Please provide three relevant WordPress websites you personally developed.
2. Have you migrated a multilingual website while preserving its SEO?
3. How would you create and verify the old-to-new URL redirect map?
4. Which multilingual WordPress solution would you recommend for this project?

IT & Networking, Information Security & Compliance
I am seeking an experienced WordPress developer to help resolve specific, well-documented file access and post-remediation issues on an existing website.
The site is hosted on a VPS and protected by SiteLock PreventPlus. Following DNS-level changes that routed all traffic through the SiteLock firewall (implemented December 23, 2025), the site has remained online and generally stable. However, a small number of legitimate site files intermittently fail to load, likely due to prior security cleanups, permission or ownership changes, or firewall/security rules that block execution of certain PHP or JavaScript files.
This engagement is assessment-first and narrowly scoped. I am not seeking a long-term maintenance contract at this stage.
My WordPress site has been flagged for possible malware. I’m not sure where the infection sits, so the first step is a full scan of core files, themes, plugins, and the database. I already have a complete backup from within the last week, so you can work confidently and roll back if anything breaks.
Once the scan identifies the threats, I need every malicious file or script removed, injected code cleaned from the database, and permissions set correctly. After the cleanup, please harden the installation—update core, themes, and plugins; enforce strong passwords; disable risky PHP functions; and configure a real-time firewall such as Wordfence or Sucuri. A concise report explaining what was found, what was fixed, and any recommendations for ongoing security will wrap up the job.
Deliverables:
• Comprehensive scan report
• Fully cleaned, malware-free site with all functionality intact
• Security hardening configuration in place
• Final summary of actions and future-prevention tips
This task is time-sensitive, so same-day turnaround is strongly preferred. Let me know your estimated completion time and any server-access details you require.

I already have a fresh Linux server waiting; what I need now is a reliable hand to bring my Next.js application to life on it and lock everything down properly. Your first task will be to install and configure Node, set up the Next.js production build, and wire it to a MySQL database. I want a clean, well-documented deployment process that I can repeat on staging and future boxes.
Beyond simply “making it run,” I expect the environment to be hardened: correct file permissions, HTTPS termination, sensible firewall rules, and system updates automated. Wherever possible, keep things lightweight—no over-engineering—yet leave me with the confidence that the stack can survive real-world traffic and common exploits.
Deliverables (acceptance criteria)
• Next.js app served by a process manager (pm2 or systemd) and reachable over HTTPS
• MySQL installed, secured (root password, remote access restrictions), and connected to the app with environment variables, not hard-coded credentials
• Nginx or Apache reverse proxy configured with SSL (Let’s Encrypt is fine)
• Basic firewall rules applied (ufw or firewalld) with only necessary ports open
• A short README or shell script that recreates the setup on another Ubuntu-based server
I’m available to provide the current repository and SSH access as soon as we agree on the approach. Looking forward to your proven expertise with Linux, Next.js, and MySQL.
Important: Automated malware scanners alone are not sufficient. We are looking for a manual forensic investigation to identify the original attack vector and all persistence mechanisms, ensuring the compromise cannot return. This is the highest priority.
We are looking for an experienced **Linux server security and WordPress malware removal expert** to investigate and completely clean a compromised VPS hosting multiple WordPress websites.
The server has already had passwords changed and basic cleanup performed, however the compromise persists. Malicious code continues to be injected into website files (including `.htaccess`), indicating that the attacker still has a method of regaining access.
We are looking for someone who can identify the root cause, completely eliminate the compromise, and secure the server to prevent future reinfections.
## Environment
* VPS hosted with Namecheap
* Linux server
* Multiple WordPress websites
* SSH access available
* Root access available
## Scope of Work
### 1. Full Security Investigation
* Determine how the server was compromised
* Identify every persistence mechanism used by the attacker
* Review system logs
* Review SSH access
* Review cron jobs
* Check startup scripts and scheduled tasks
* Inspect all websites for backdoors
* Identify vulnerable plugins, themes or outdated software
* Verify there are no malicious Linux users, SSH keys or hidden services
### 2. Website Cleanup
* Remove all malware and malicious code
* Remove web shells and hidden PHP files
* Clean infected `.htaccess` files
* Verify WordPress core integrity
* Verify plugins and themes
* Remove injected JavaScript or redirects
* Ensure every hosted website is clean
### 3. Server Hardening
* Close the security hole that allowed the compromise
* Harden the VPS against future attacks
* Secure SSH
* Review file permissions
* Configure firewall if necessary
* Disable unnecessary services
* Apply security best practices
### 4. Password & Credential Review
Review and advise on any credentials that should be rotated, including:
* Create a verified clean backup of the entire hosting environment
* Ensure the backup can be restored if needed
### 6. Documentation
Provide a short report including:
* How the compromise occurred
* Files that were infected
* What was removed
* What security improvements were made
* Recommendations to prevent future compromises
## Required Experience
Please apply only if you have experience with:
* Linux server administration
* VPS security
* WordPress malware removal
* WordPress forensics
* Apache/Nginx
* SSH
* Malware persistence
* Root cause analysis
## When Applying
Please include:
* Similar compromised VPS recoveries you have completed
* Your approach to identifying persistent infections
* Your estimated timeline
* Your fixed price or hourly rate
This project requires finding the **root cause** of the compromise—not simply deleting infected files. The work will be considered complete only when the server is fully cleaned, hardened, verified, and a clean backup has been created.
Funds will be released after 7 days of job completion to make sure that the issue does not reoccur
