I have an upcoming Azure administration interview and I’d like focused, one-on-one coaching to sharpen the areas that matter most: Azure infrastructure management, monitoring and security, and Azure DevOps. My current skill set sits at an intermediate level—I work with Azure regularly but need help turning day-to-day know-how into concise, interview-ready answers. I’m looking for a coach who can: • Walk through real-world scenarios and white-board style discussions that map directly to those three domains • Spot and close any knowledge gaps quickly • Provide actionable feedback after each session so I can keep refining between meetings If you use tools such as Azure Portal, Azure CLI, ARM/Bicep, Azure Monitor, Security Center or DevOps pipelines ...

I have a brand-new travel router that still sits in its factory state. I want it fully ready for my next trip, so the task is the initial setup and configuration from start to finish. Here’s what I need: • Configure the router so it can accept an incoming Ethernet cable as its WAN source, then broadcast a secure Wi-Fi network for personal use while I’m on the road. • Set SSID, strong WPA2/WPA3 password, admin credentials, time-zone, and any essential regional settings. • Apply best-practice security options: disable unnecessary services, change default ports if advisable, and verify the latest stable firmware is running. • Walk me through or remotely perform the setup (TeamViewer, AnyDesk, or a similar tool works for me) and leave me with a short, s...

Each week I need a concise, technically sound report that traces the full HTTP / HTTPS journey of my iOS app from user login through to the payment screen. The focus is on what happens over the wire, not on actually making a purchase. Scope of the weekly task • Capture every reachable endpoint hit during the flow, including the exact request method (GET, POST, etc.). • Log request and response headers, plus payloads—with sensitive data masked. • Note response codes, body structures, and any tokens or cookies that govern session continuity. • Highlight how the session is created, refreshed, and closed. • Summarise unusual patterns (retry logic, polling, WebSockets, certificate pinning, etc.) that surface during traffic inspection. An authorised tes...

I’m bringing a new Mikrotik router into service and want the initial network build done right the first time. Your job is to plan and implement the complete setup—interface assignments, WAN/LAN segmentation, DHCP, NAT, basic firewall rules, and any best-practice tweaks that keep the installation secure and future-proof. I will give you remote access to the device (RouterOS current stable release) along with the addressing details and any special VLAN or wireless requirements once we agree on the engagement. I expect clear notes of every change you make so I can maintain the router after hand-over, plus an export of the final configuration for backup. If you have the Mikrotik certification and have set up small to mid-size networks before, this should be a fast, clean project.

I need a technician who can quickly set up port forwarding on my Peplink router so that external traffic reaches an internal web server without interruption. The router is already online and I can provide remote access to the Balance dashboard along with current network diagrams. Scope of work • Create the necessary NAT or inbound access rule on the Peplink to expose the web server. • Map the correct public-to-private IP and confirm the right TCP ports for standard web traffic. • Verify that the rule does not conflict with existing policies or VLAN settings. • Test from an outside network and confirm the site is reachable. • Send me a short record of the final configuration so I can re-apply it if the unit is ever reset. Peplink OS experience is essenti...

Hi I will share the details with the shortlisted candidates. Thanks

I need a seasoned Peplink specialist to step in and configure a Peplink Balance that sits at the core of our enterprise network. The device is already racked and cabled; what’s missing is a clean, best-practice configuration that supports our production traffic without bottlenecks or security gaps. The job involves reviewing the current settings (mostly factory defaults), advising on any licensing or feature activations I should consider, then applying the agreed-upon configuration directly on the device via the web admin or InControl 2. Performance, resilience, and security are equally important to us, so I expect sensible load-balancing rules, streamlined WAN failover, and locked-down admin access in line with enterprise standards. Deliverables • Final running configuratio...

I have a Cisco UC540 on-site and a live SIP trunk supplied directly by our ISP. All the registration details—SIP username, password, registrar, codecs, DID ranges—are already in hand; what I need is a specialist who can jump in remotely, register that trunk on the UC540 and make sure both inbound and outbound calls flow cleanly. Here is how I picture the engagement: • Remote configuration through CCA or pure CLI, whichever you are most efficient with. • Correct dial-peers, voice class codecs and translation rules so our full DID block reaches the right ephone-DNs and outbound calls present the main number. • Basic feature verification: two-way audio, multiple simultaneous calls, caller-ID, and voicemail routing to CUE. • A brief hand-over showing the...

My SonicWall firewall needs its VPN function brought back to life, but I no longer have an active licence or support contract to lean on. The goal is simple: Windows-based staff must be able to connect reliably, without drops, and at normal speeds. I can give you full remote access to the appliance, the current configuration file, and a test Windows machine. What I need from you is a clean diagnosis, the necessary CLI or GUI tweaks, and any creative work-arounds that avoid licence-gated features while keeping security tight. If firmware needs to be upgraded or rolled back, please guide me through a safe procedure so we don’t lock ourselves out. Deliverables: • Restored, stable VPN access from at least one Windows PC (I’ll supply the test credentials). • A brief ch...

I have a Syrotech OLT that is up and running but still throwing configuration errors that are holding back overall throughput. My goal is to tune the existing setup so the network performs at its peak without dropping packets or creating unnecessary latency. The basic provisioning is already done—VLANs and user profiles are not the pain-points right now—so I need an expert who can dive straight into performance-oriented parameters, spot the mis-configured elements, and correct them in real time. A solid track record working directly on Syrotech (or comparable GPON) equipment is essential, and I’ll weigh your experience heavily when I decide whom to invite for a remote session. CLI-level familiarity, understanding of Syrotech firmware quirks, and the ability to document t...

I’m looking for an extra pair of expert hands to keep several integrated security environments running smoothly. Day to day you will dip into CCTV/NVR platforms, Genetec-based VMS, Windows workstations and servers, access control panels, and the supporting LAN. When something misbehaves I’ll count on you to isolate the fault, correct it, and record exactly what was done so the fix is repeatable. Beyond urgent tickets, I also need periodic system reviews: checking firmware levels, validating camera coverage, confirming storage retention, spotting bandwidth bottlenecks, and flagging any compliance gaps. The insights you gather should flow into clear Excel reports, updated SOPs, and other technical documentation that management can act on. If you apply, highlight the depth of yo...

I have a complete code-base that now needs to live on a cloud server. The immediate goal is twofold: 1) install and configure the application so it runs reliably in the cloud environment I provide, and 2) comb through every file, dependency, and configuration to confirm there are no hidden backdoors, malicious packages, or insecure default settings left behind after development. I’m deploying to a cloud server (provider is flexible, so please be comfortable with AWS, Azure, or GCP). You’ll set up the runtime stack, handle environment variables, connect the database, and push the first production build. While doing so, perform a thorough security audit: manual inspection, automated scanners, and any static-code-analysis tools you trust. If something suspicious appears, docu...
