I’m ready to bring one committed sales professional onto my team for the long haul. Your core mission will be lead generation in the finance space, turning cold data into warm, qualified conversations that keep our pipeline healthy. Here’s what day-to-day success looks like for me: you research and identify decision-makers inside banks, fintechs, and investment firms, open doors with persuasive outreach, and keep the relationship alive until they’re ready for a demo. You’ll lean heavily on LinkedIn — both organic connection building and Sales Navigator searches — and support that outreach with AI-assisted social posts that you craft and schedule on Facebook to widen our visibility. I need someone who can: • Consistently deliver fresh, finance-sec...

I need a complete examination system that runs entirely over our local Windows network, so students can sit an “online” test without any internet connection. The solution must let each workstation connect to a central server, pull the exam, and push results back immediately. Key capabilities • Randomized question order so no two students see the same sequence • Per-student time tracking with an automatic lock-out when the clock hits zero • Automated grading that releases scores the moment an exam is submitted Question formats to support • Multiple choice • Short answer • Essay Administrators have to be able to build question banks, schedule exams, watch real-time progress, and export detailed results. A simple, distraction-free candi...

I have an old FreeBSD installation that boots; I copied the entire disk image onto a USB drive and now need the document files extracted. The priority is .doc and .pdf documents that were kept inside a handful of specific directories (I’ll send their full paths once we start). The job is simple in scope but requires solid FreeBSD / UFS-2 recovery know-how. You will need to: • Mount or image-clone the USB safely (read-only first). • Locate the requested directories and pull every .doc and .pdf you can find. • Verify file integrity—open the recovered documents or run hash checks so I know they are intact. • Package the results in a tidy archive and hand it back to me, along with a brief log of what you did (commands, tools, and any issues encountere...

I run a CS-Cart store on a single AWS Lightsail instance and want to hand the monthly server care to an experienced admin. Each month you will keep the operating system and any installed packages fully patched, monitor resource usage so the shop stays snappy during traffic spikes, and maintain a reliable backup routine that can be restored quickly if ever needed. Key deliverables • Security updates & patches applied and logged • Performance metrics reviewed, tuned and reported (CPU, RAM, disk, database) • Automated snapshot / off-site backups configured and verified Familiarity with the Lightsail console, SSH, Linux, and basic CS-Cart requirements is important. I’ll grant you limited IAM access; after each maintenance window I expect a short summary of wh...

I have a brand-new Microsoft Co-Pilot Studio tenant and a fresh Azure subscription that must be production-ready within the next hour. Your job is to screen-share with me, walk through the initial setup and configuration of Co-Pilot Studio, and connect the required Azure resources so I can begin building copilots immediately. The priorities are clear: • Complete the first-time configuration of Co-Pilot Studio, including any mandatory policy or tenant settings. • Stand up the minimal Azure services needed for Co-Pilot to run smoothly (I expect Azure AD, Key Vault and Monitor may come into play, but I’m open to your proven approach). • Apply security best practices so no sensitive business data ever leaves our tenant—think tight access controls, private endpo...

I’m looking for an admin who can jump in right away and take full ownership of my fleet of Linux machines. Ubuntu is the operating system I touch most often, but you’ll also encounter CentOS, AlmaLinux and the occasional Rocky host, so cross-distro confidence is essential. Day-to-day you’ll be spinning up and hardening both Apache and Nginx stacks, tuning MySQL / MariaDB, and moving WordPress sites between servers without a hitch. When DNS records misbehave, SSL renewals fail, mail queues clog or performance suddenly tanks, I’ll rely on you to diagnose and fix the root cause—fast. Most of the infrastructure sits on VPS nodes in AWS and Azure, with a few “traditional” dedicated boxes. Familiarity with cPanel, Plesk and DirectAdmin will save ti...

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...

My outbound mail reaches Gmail and every other provider perfectly, yet anything sent to Outlook, Hotmail or (Microsoft) still heads straight to junk or they don’t get it at all . The domain is hosted on delicated server from and I have full access to all DNS and server-side settings, so making technical changes is not an issue. SPF, DKIM and DMARC are already correctly published and passing; Microsoft support tickets have been opened more than once, and I have tweaked header settings, sending patterns and content, but the problem always returns. I want a definitive fix that keeps the domain off Microsoft’s spam list for good, not a temporary workaround. Here is what I need from you: • A comprehensive audit of my current configuration, including header analysis, send...

My production EC2 instance (Linux) has become unusable and I need it brought back online quickly and safely. The immediate priority is to recover all databases plus the critical file and directory structure; however, if the damage proves deeper, I am open to doing a full-system restore instead of just a data-only recovery. You will need to evaluate the current snapshots, AMIs, and any available backups, then advise whether a point-in-time data restore will suffice or if we should spin up a brand-new instance and perform a full system restoration. Key expectations • Recover databases as well as file/directory data without loss or corruption. • Verify application services start correctly on the restored instance. • Document each step so future rollbacks or disaster...

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’m running a 3CX Professional installation where voicemails have suddenly stopped being stored on the server and are no longer reaching users’ mailboxes. The PBX hasn’t been updated recently, so this isn’t tied to a new build or hot-fix. What I’ve already covered: I verified the voicemail settings, restarted the whole system, and combed through the logs, yet I still can’t see any obvious misconfiguration or error that explains why messages vanish. Here’s what I need from you: • Pinpoint the exact cause of the voicemail failure (storage path, permissions, SMTP issues, service crashes—whatever the root happens to be). • Apply or walk me through the fix during a remote session so that new voicemails are both retained on the PBX ...

I need an experienced administrator to take full responsibility for a Windows-based VPS that hosts my live projects. Your role is to keep the server healthy, secure, and running smoothly under an ongoing contract. Please be fully comfortable with Windows Server environments, remote desktop administration, PowerShell, firewall configuration, backup planning, and disaster-recovery best practices. 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...
