Automated messages from my domain are dropping straight into spam folders on Yahoo, Hotmail, iCloud, Gmail and some Outlook accounts. I’ve already pinpointed the likely culprits—mis-configured SPF, DKIM and DMARC records—but need an expert pair of eyes to sort them out quickly. Here’s the current landscape • DNS is hosted on Simply. • Emails are sent through Resend via Supabase Edge Functions.

I’m currently living behind Iran’s ever-tightening firewall. Virtually every international site or service is unreachable, yet I do have a single VPN profile that still punches through. I don’t know whether it relies on residential IP routing, a stealth transport layer, custom TLS camouflage, or something else entirely—but it works, and I need to understand why so I can keep reliable access going forward. Here’s what I’m hoping you can do for me: • Examine the configuration file and any accompanying certificates or keys I supply, reverse-engineer the protocol or obfuscation technique in use, and clearly document the mechanics in plain language. • Show me how to replicate the same approach on my own infrastructure (VPS or residential tunnel...

I am ready to move our organisation to CMMC Level 1 and need a specialist who can guide the entire process from assessment through remediation and documentation. The scope spans three core areas—network security, data protection, and user access control—across all production servers, employee workstations, and our small fleet of mobile devices. Our environment is a typical Microsoft-centric stack with a mix of on-prem VMware hosts, Office 365, and a few SaaS applications that handle Federal Contract Information. What I need first is a concise gap analysis mapped to CMMC Level 1 requirements (aligned with NIST 800-171 Rev 2). From there, we will prioritise fixes, implement the missing safeguards, and collect artefacts that demonstrate ongoing compliance. I expect clear document...

The ZXA10 C320 is already racked, powered, and reachable over the management network; what I still need is a clean, production-ready configuration and the supporting tools around it. ZTE OLT • Bring the firmware up to the latest stable release. • Build an intuitive, comment-rich start-up config that includes all required VLANs and properly provisioned PON ports so that adding new ONUs is a one-command job. • Document every step so future changes remain “copy-and-paste” simple. NetNumen NetNumen will run on a fresh Windows Server VM.

I need an experienced DevOps engineer to streamline my AWS infrastructure. The immediate priorities are automating all deployment processes, standing up a clean CI/CD pipeline, and wiring in robust monitoring with alerting. The stack lives entirely in AWS, so familiarity with its core services—EC2, ECS or EKS, IAM, CloudWatch, and related networking components—is essential. Terraform is the infrastructure-as-code tool of choice; everything must be defined, version-controlled, and repeatable in Git. Deliverables • Terraform code that provisions the complete environment from scratch • A CI/CD pipeline (GitHub Actions or similar) that builds, tests, and promotes to staging and production automatically • Monitoring dashboards and alert rules in CloudWatch (or e...

I’m looking for a Europe-based freelance IT engineer who can design, install, and maintain a reliable Local Area Network focused on routers and switches. The cabling is already in place, so I need someone who can come in, assess the existing environment, recommend any additional hardware if required, configure everything for optimal performance, and make sure the network scales easily as our headcount grows. Once the core is live I’d like occasional proactive maintenance and rapid, on-call troubleshooting when issues pop up. Familiarity with the major enterprise switch and router vendors is essential, and I’m happy to work with you on firmware standards, VLAN segmentation, and best-practice documentation. Deliverables I expect: • Detailed implementation plan (inclu...

I’m rolling out a new Local Area Network in several European offices and need the Wi-Fi layer deployed end-to-end. The scope centres on network setup and ongoing maintenance, with a focus on installing, configuring, and optimising access points so every workspace enjoys seamless coverage. You will start with a short remote planning call where I provide floor plans and current cable routes. From there, you’ll advise on access-point counts, placement, channel planning, and any controller requirements, then be hands-on on site (or coordinate local hands) to mount, patch, and bring the APs online. I’m happy to work with whichever enterprise hardware you’re most comfortable with—Cisco, Aruba, Ubiquiti UniFi, or similar—as long as the final network meets roam...

Our production file-share runs on AlmaLinux with Samba and I’m seeing sluggish transfer speeds that vary wildly across mixed file types. I’ve ruled out basic network congestion, so the bottleneck is almost certainly in the current Samba configuration. Here’s what I need: • Pinpoint and eliminate any configuration errors that could be throttling throughput. • Tune and related system parameters for consistently fast transfers of both large binaries and many small documents (the workload is truly mixed). • Document each change, why it was made, and the performance delta observed after the adjustment. Acceptance criteria: after your tweaks, average transfer speeds for a representative mixed-file batch must meet or exceed gigabit-line expectations,...

I’m ready to move an existing site onto fresh infrastructure and need someone who can jump on a live screen-share with me right away. The work is entirely remote and centres on two providers—DigitalOcean and Vultr—running on dedicated instances. Here’s what has to happen during the session: • Spin up the new droplet / bare-metal node, harden it, and install the essential web stack. • Migrate the current website from its old environment with zero data loss and minimal downtime. • Point and verify DNS so the domain resolves correctly once propagation finishes. The operating system has not been finalised; I’m leaning toward Ubuntu, but I’m open to quick guidance if another distro makes more sense for performance or security. I’l...

Title: Developer Needed to Build Monitoring Platform Using EZVIZ API / SDK (Fixed Price Project) Description Hello, My name is Alex. I run a security company operating a monitoring center. We have many EZVIZ cameras (model H9C) installed across multiple client sites. Currently, these cameras are installed without any NVR on the client sites. We access them remotely using EZVIZ PC Studio, which is mainly designed for home or small installations and not suitable for professional monitoring. Important note: EZVIZ H9C cameras do not provide RTSP streams, so the system will likely need to use the EZVIZ Developer Platform (Cloud API / SDK). What we want to build We want a centralized monitoring platform where our operators can monitor cameras from many different sites. Ideally, the sys...

I need someone based in Russia who can walk me through, and if required remotely execute, the full setup of a VPS that will physically reside on Russian soil. My priority is simply getting the server online and production-ready; once it is running smoothly I will maintain it myself. We will start by choosing a reliable Russian provider, spinning up the VPS, and installing the usual stack (Linux + either Nginx or Apache, plus SSL, firewall hardening and basic monitoring). You will also take care of the initial configuration so the site loads over its domain the moment I point the DNS. Russian-specific compliance requirements, if any, should be covered as part of the setup. Deliverables • Active Russian-based VPS with root access handed over • Web server, SSL, firewall an...

I want my Ubuntu server configured as an OpenVPN host that lets me and a small team (fewer than ten users) connect securely from anywhere. The goal is straightforward: reliable, encrypted remote access without having to worry about manual key generation, firewall tweaks, or routing issues each time we add a new device. Here’s what I expect at the end of the job: • OpenVPN installed and running on my existing Ubuntu server (latest LTS). • User-friendly client configuration files or .ovpn bundles for up to ten devices, plus a quick guide so I can generate more later if needed. • Firewall and IP forwarding rules adjusted so traffic is tunneled safely while the rest of the server’s services keep working as they do now. • Basic security best practices ap...
