System Admin Jobs

A recently rebuilt Windows workstation needs a bullet-proof antivirus setup carried out over a remote session. The job begins with selecting an effective AV suite (I am open to your recommendation—Norton, McAfee, Kaspersky, or another best-in-class option) and continues through full installation, optimisation, and hardening. Key protection goals • Online banking: isolate browser sessions, enable real-time phishing & key-logger defences, and verify safe-transaction modules are active. • Confidential files: enforce on-access scanning, tune heuristic settings for maximum detection, and lock down local folders with password-protected vaults or encryption available within the AV. • Google Drive sync: ensure cloud-storage scanning is enabled, block malicious file ...

I need an experienced Microsoft 365 specialist to move our logistics company, NUVECA, completely off Zoho Mail (1–10 accounts) and onto a new Microsoft 365 tenant. Every message and folder must arrive intact. Our domain is registered on Porkbun and server access is handled by an internal IT teammate. You will supply him with the exact DNS records—MX plus the correct SPF, DKIM and DMARC entries—and stay on top of propagation until all checks pass. Once mail is flowing through Microsoft 365, I also want our website contact form to relay through the new SMTP service so that enquiries hit the right mailbox without fail. We currently open mail in Thunderbird, Outlook and Webmail, so those clients have to connect smoothly after the cut-over, with clear instructions we can han...

I’m ready to rebuild my GoDaddy VPS: it currently runs CentOS and hosts my company websites behind Nginx with SSL enabled. I want the server re-imaged to the latest stable Ubuntu, with every element of the existing stack preserved and an additional n8n instance installed. Scope of work • Perform and store an off-box, full backup of all site files, databases, and current Nginx configurations before any changes begin. • Re-provision the VPS on Ubuntu, harden the OS, and apply basic firewall rules. • Restore my websites, bringing Nginx back online with the original virtual host blocks and SSL certificates so no visitor notices the change. • Install n8n (Docker or native systemd service—whichever fits best on Ubuntu) and expose it securely over HTTPS ge...

I need reliable freelance computer-hardware engineers who can visit my customers’ offices and homes across India and carry out installation services—specifically Linux installation on their machines for everyday desktop use. Here’s what a typical call looks like: I send you the location and preferred Linux flavour (most often Ubuntu or Mint, though customers occasionally ask for Fedora or Debian). You arrive on site with a bootable USB/DVD, install the OS on a new or existing desktop or laptop, set up common drivers, configure the network, and verify that everything—from Wi-Fi to printers—works smoothly before hand-over. I cover any reimbursable travel expenses that we agree on in advance, and you invoice me once the job is signed off by the customer. So...

I run a production-level Windows server that now needs steady, professional care. The box is already up and live; what I need is someone who can step in and take over the routine work that keeps it healthy and secure.

My Cisco Firepower FPR-4110-K9 is due for a full software refresh and I need a Cisco-certified network-security specialist to guide me through it in real time. The immediate task is upgrading both ASA and ASDM; I don’t yet have the latest images or the necessary Cisco download privileges, so part of the engagement is helping me obtain (or using your own account to retrieve) those files through authorized channels only—no third-party sites. We will connect via screen-share, SSH, or direct console so you can walk me through each step, verify integrity, back up the current configuration, and perform the install with minimal downtime. Deep familiarity with the ASA code train on Firepower 4100 series hardware, version prerequisites, and ASDM setup is essential, along with comfort w...

Digital Chain of Custody for Forensic Evidence ​Concept: A system for police and legal teams to track digital evidence (logs, hard drive images, CCTV footage) without tampering. ​The Problem: In court, digital evidence is often dismissed because the defense claims it was tampered with after seizure. ​The Solution: When evidence is collected, a cryptographic hash (SHA-256) of the file is generated and stored on a Blockchain. Every time the evidence is "checked out" or viewed by an officer, a transaction is recorded. If the file hash changes even by one bit, the Blockchain rejects it. ​Tech Stack: ​Frontend: React.js or Flutter. ​Blockchain: Ethereum (Sepolia Testnet) or Hyperledger Fabric (for private permissioned access). ​Storage: IPFS (InterPlanetary File System) to store the a...

I’m looking for an experienced desktop-support professional who can step in and look after every aspect of my Windows machines. I run a mix of personal PCs and small-office workstations, so the environment shifts between home-use convenience and business-grade reliability.

I’m collecting authentic, two-person conversations to expand a voice-recognition training set. If you are a native speaker of Swiss German, Irish, or New Zealand English, you’ll pair up with another native speaker of the same variety and record a spontaneous chat in a quiet setting. No scripts—just natural dialogue on everyday topics so the acoustic model captures genuine speech patterns. You will receive simple recording guidelines (file format, minimum duration, topic suggestions, privacy notes) once we match. Please make sure both voices are clear and balanced; mobile phone mics are fine as long as the environment is quiet. Deliverables • One high-quality audio file of the full conversation • A brief text log with participant names, language variant, an...

I run a network that relies on a mix of Cisco FTD devices managed through FMC, Fortinet FortiGate units, and several Palo Alto firewalls. Day-to-day, I need hands-on help keeping our site-to-site VPN landscape healthy and expanding it whenever new locations come online. The core of the job is daily network security troubleshooting—tracking down dropped route-based or policy-based tunnels, fixing mis-timed Phase 2 proposals, untangling unexpected NAT behaviour, and dealing with the odd switching quirk that pops up when VLANs or trunks change. When everything is stable, I turn to creating new tunnels, building them end-to-end and documenting the exact CLI/GUI steps so the team can replicate your work later. I value engineers who already hold (or operate comfortably at) CCNP- or CCI...

I already own an AWS EC2 instance and now need a solid, production-ready Ubuntu environment on it. The job is strictly setup and configuration: Ubuntu is the chosen distribution, so I want the latest LTS image installed (or upgraded if you prefer an in-place build), all initial security hardening applied, and the machine prepared for day-to-day use.
