I need someone who can quickly repoint my . domain registered with TPP Wholesale so that any visitor is taken to a different *exact URL* for the product supplier . The site itself runs on a private server, so the job is limited to updating the DNS and confirming that the redirect works across all major browsers once propagation is complete. e.g. points to I will give you access to the TPP Wholesale control panel as well as to the server’s virtual host file if an on-server 301 is the cleaner route. As long as the end result is a seamless, permanent redirect *without breaking any existing email records* - I’m happy. Please let me know how soon you can start, what information you’ll require from me first, and roughly how long you expect DNS propagation to take in yo...

I may need 5-7 sessions of 45 mins to an hour, early UK hours On high-performance computing and want clear, actionable insight into where the field is heading. The emphasis is firmly on future HPC roadmaps, covering algorithms, hardware, and the emerging software tool-chain—while still grounding the discussion in today’s production realities such as Open OnDemand (OOD), GitLab, Slurm, Linux and Cloud-based extensions. Here’s how I’d like us to work together: • Kick-off call: HPC best practices, HPC challenges, and HPC overview. • Working sessions (2–3): walk me through the near- and long-term HPC roadmap, then zero-in on quantum computing—detailing quantum algorithms, hardware architectures, and software tools. Deliverables 1. Slide ...

I need an experienced systems engineer who can dive straight into our Windows Server 2012 R2 environment and a fleet of Windows 10 workstations. The first assignment is to stabilise, harden, and document these platforms, but you will also touch the broader estate that includes LAN/WAN gear, backups, MS-SQL, IIS 8+, and collaboration services such as Office 365, OneDrive, and G-Suite. Day-to-day you will: • Review and correct Active Directory, Group Policy, DNS, DHCP, and IIS configurations. • Patch servers and desktops, close security gaps, and verify compliance. • Optimise login scripts, roaming profiles, and folder redirection for Windows 10 users. • Troubleshoot escalated tickets through our help-desk tool and provide clear resolution notes. • Coordin...

A batch of new switches is arriving at our premise and I need reliable smart-hands assistance to swap them in without interrupting service. The job is strictly on-site and centres on a wired network setup: unplug the legacy hardware, mount and cable the replacement devices, power-test, and clear the rack of the retired units for collection. You will be guided in real time by a remote engineer who will confirm port assignments and link-light checks. No software configuration is required—just precise physical work and the ability to follow clear, step-by-step instructions while keeping everything tidy and properly labelled. Deliverables • New devices physically installed, patched and powered on • Old devices removed, boxed and labelled for return • Photogr...

Ideal candidates should have expertise in networking, proxy systems, and related configurations.

I need a Remote Access VPN set up on my Fortinet firewall so that staff can connect securely from outside the office using FortiClient. The connection will rely on simple password-only authentication—no tokens or certificates this time—so the job focuses on properly creating user accounts, assigning policies, and ensuring encryption settings follow Fortinet best practices. Here’s what I expect once you’re done: • A working FortiClient profile that users can import and connect with. • All necessary firewall objects, user groups, and security policies configured and saved. • Clear step-by-step documentation so I can duplicate the setup or make edits later. • A brief remote test session to confirm that the tunnel comes up, internal resources are re...

I need a well-researched, publish-ready case study that examines how a technology company strengthened its overall network security by redesigning its firewall implementation. The goal is to show, step by step, what triggered the initiative, which design choices were made, how the solution was deployed, and what measurable results followed. Scope • Center the narrative on network security within a real or anonymized technology-sector setting. • Give special, in-depth attention to firewall architecture and rule-set hardening; intrusion detection systems or VPN references are welcome only where they help explain the firewall strategy. • Blend technical detail—vendor models, topology diagrams, configuration highlights—with business impact (risk reduction, com...

I expect you to: • Proactively handle updates, patches, and routine maintenance without disrupting uptime. • Watch key performance metrics, resolve bottlenecks, and react fast to any alerts. • Document each action you take so I always have a clear history of changes. When you apply, outline the monitoring tools you prefer (e.g., PRTG, Zabbix, or native Windows utilities) and how you...

I have a single Google Cloud VM that serves both my application (Nginx) and its database. I’d like to harden it by adding a cloud-native firewall layer and turning on full traffic visibility. Here’s the scope: • Use GCP’s built-in VPC firewall (no third-party appliances) to create the rule set. • Configure it so that every ingress and egress packet is logged to Cloud Logging; I want to be able to audit both directions at any time. • Rules must allow normal web, SSH and internal DB traffic but block anything unnecessary, following least-privilege principles. • Deliver a brief summary or screenshot set that shows the rules, their priorities, and where the logs are flowing so I can replicate the setup later if needed. If you’ve already done...

I’m looking for clear-headed guidance on the technical implementation side of my project. Rather than hands-on coding or design work, what I need right now is expert consultation: someone who can listen to the current concept, analyse the requirements, and then recommend the smartest way forward—architecture, stack choices, integration steps, potential pitfalls, timelines, and any pertinent best practices. The engagement will be structured around a set of focused calls (video or voice) followed by concise written takeaways so I can put the advice into action straight away. If you have a track record of translating complex technical challenges into practical, step-by-step plans, let’s talk.
