I’m expanding a GoHighLevel-based business with sites and need a dedicated partner who can own both the SEO roadmap and the everyday admin work inside GHL. The immediate mission is to push our pages up the rankings. My biggest pain point is on-page SEO, and phone registrations so you’ll start by reviewing content, keywords, meta-tags and internal links across the whole site builder. From there, we’ll map new keyword clusters, adjust page structures for better crawlability, and monitor results through GHL analytics and Search Console & SE Ranking. Content creation is part of the job. You’ll draft and publish fresh blog posts, polish product and service descriptions, and fine-tune landing pages so every piece lines up with our target phrases. I move fast, so th...

I have two web applications that must follow the same Cloudflare + R2 pattern already running on a third project, so you can reference an existing working setup rather than starting from scratch. For Cloudflare, clone the configuration, update the DNS records, enforce Full (strict) SSL/TLS, and replicate the essential firewall rules we use to keep the apps locked down. Both sites need to be fully functional behind Cloudflare once you are done. Each application also requires its own R2 bucket. One will store user-uploaded content; the other will host a set of static HTML files. Please create the buckets, set the correct CORS and access policies, and update the applications so they read and write to R2 seamlessly. Finally, I need to move off Resend. Spin up a new mail server, migrate th...

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 an experienced network-oriented systems engineer to install and fully configure a Broadband Network Gateway (BNG) that will run on a Linux platform. The exact application mix is still open, but the core requirement is a stable, production-ready BNG that can authenticate subscribers, shape traffic, collect usage data, and hand off sessions cleanly to my existing upstream routers. You will decide the most appropriate Linux distribution and tool-chain, document every step, and leave the server in a state where I can add or remove service modules later without downtime. A strong background with PPPoE, DHCP, RADIUS, IPoE, QoS policies, and high-throughput tuning under Linux is essential. Deliverables • A clean Linux installation, hardened and updated • Fully operational BNG...

I need a hands-on network engineer who can come in immediately and take care of the physical side of a new Juniper rollout.

Looking for Data engineer on AWS with 10 plus years of experience who are willing to work 2 hours daily

I need an experienced technical support engineer who can resolve software-level issues on both Windows and Linux systems. Typical requests will include troubleshooting application errors, installing or updating packages, and guiding end users through configuration steps.

I’m looking for a safety specialist who can support small businesses with end-to-end safety compliance. We are looking to engage a contractor to deliver outcomes to our existing and growing client base. We are not looking for someone who will just do an inspection and issue a whole lot of documentation and then wish everyone the best and leave behind business owners with more work and nothing actually implemented. The role will be imbedded into the small businesses on a fractional basis, like you are a member of the team. For example - Identify hazards AND implement the controls. Conduct toolbox meetings AND ensure consultation is recorded. Manage incidents from start to end. Be the return-to-work coordinator. Monthly reporting to business owners. Develop safety onboa...

My stack already lives on AWS and it’s time to tighten things up and make it scale smoothly. The focus is squarely on EC2 and S3. • EC2 – design and implement an Auto Scaling strategy, wire it to a load balancer, and harden the instances so they meet current security and compliance best practices (IAM roles, security groups, patching, CloudWatch alarms, the works). • S3 – review existing buckets, lock down access policies, enforce least-privilege IAM, and confirm encryption is applied at rest and in transit. All changes must be applied through repeatable steps—CloudFormation or Terraform are fine—as long as I can redeploy the same configuration in another account and get identical results. I’ll provide current account diagrams and limit...
