I have an ESP32 based product that should maintain a steady Wi-Fi link, yet on my home network it keeps dropping off and taking too long to re-associate. Stability and reliability are my chief concerns; speed is acceptable once the board reconnects. The task is straightforward: go through the existing codebase, spot whatever is undermining the connection logic, and supply clear, working fixes. Serial logs, event callbacks, power-saving modes, and DHCP handling are all fair game—whatever it takes to stop the frequent disconnects. Deliverables • Annotated version of my original source showing every change made • A concise technical note explaining the root cause and the remedy (1–2 pages) • A quick reconnection stress-test script or steps I can replicate to p...

I’m expanding our field team and need on-site technicians who can rack, cable, and turn up routers, switches, and firewalls across the UAE, Bahrain, Saudi Arabia, most African nations, and a wide stretch of Eastern Europe—including Poland, Hungary, the Czech Republic, Greece, Slovakia, Slovenia, Croatia, Bulgaria, Romania, and Turkey. Most of the gear you’ll see is Cisco—Catalyst, Nexus, Meraki—as well as Aruba, Lanner, and the occasional white-label device. Jobs range from a single cabinet in an office to multi-rack deployments in Tier III data centers or rugged industrial plants. You’ll work with my remote engineering team over Webex or Teams while you handle the physical layer: unboxing, rack & stack, structured cabling, console access, initial i...

I need an experienced system engineer to spend a single day at our client’s site acting as the hands-on field resource while my remote team handles the configuration. Your focus will be the physical side: racking, cabling, powering on, patching, and verifying a mixed stack of servers and switches, desktops and laptops, plus printers and firewalls. On arrival you’ll follow the step-by-step build sheet we provide, attach console or management leads so the remote crew can take control, then run quick power-on and connectivity checks. Before leaving, test that users can log in, reach the network shares, and print without issues. A concise wrap-up note (what was completed, any snags, and current device status) closes the assignment. Deliverables • All listed equipment f...

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...

I have a batch of brand-new desktop computers that need to be unpacked, assembled, and brought online in our office. The task covers the complete hardware setup—mounting any internal components, connecting peripherals, verifying BIOS settings—followed by operating-system installation, driver updates, and joining each machine to our wired LAN. Cable runs are already in place; you’ll simply patch the PCs to the switch, confirm DHCP or static addressing (as we decide on site), and test connectivity to shared printers and our file server. Please centre your bid on your hands-on experience performing similar roll-outs rather than lengthy proposals. A concise note about previous desktop deployments, the tools you rely on (e.g., Windows 11 Pro imaging, PXE boot, Clonezilla, or ...

I need a hands-on network engineer for a single day of onsite work. Your main task will be to rack, stack, power up, and cable two types of devices—routers and switches—exactly as shown in the network diagram. Once everything is patched, you’ll open console access so our remote team can jump in and finish the configuration. Deliverables for the day • Routers and switches physically installed, powered, and neatly patched • Verified console connectivity for each device • Any laptop or printer glitches resolved or clearly documented • A brief hand-off report summarizing what was done and noting anything that needs follow-up Bring your own basic toolkit (screwdrivers, cable tester, console cable, etc.) and be comfortable working independently whi...

I need a fast, professional Ekahau site survey so I can design a rock-solid wireless network for our warehouse. The goal is to walk the entire facility, collect accurate RF data, and translate the results into a clear deployment plan. We are starting from scratch, so every recommendation you make—access-point count, model, mounting height, channel plan, power settings—will directly shape the installation. Timeline The sooner the better; I’m ready to move as soon as you are and would like the full survey and report wrapped up ASAP. What you will deliver • Ekahau project file (.esx) with all raw survey data • Heatmaps for signal strength, SNR, throughput, and interference • Annotated floor plans showing exact AP locations and cable drops • Ch...

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 preparing to replace our legacy MPLS links with the SD-WAN service we’ve already contracted and need an on-site engineer in Hyderabad, Telangana to drive the entire cut-over. The environment is small—fewer than 50 routers, switches, firewalls, and edge devices—but the migration still has to be planned and executed with zero-downtime goals. Here’s what I expect: • Audit the current MPLS topology and document every dependency. • Translate existing QoS, security and routing policies into the new SD-WAN orchestrator. • Build and stage configs on the vendor-supplied edge appliances. • Coordinate with our carrier and internal teams to schedule and perform the live switchover. • Validate traffic flow, fail-over behavior, and app...
