    I am proficient with all large public cloud - AWS/Azure/GCP, and a few of the smaller ones - Linode/Digitalocean/Scaleway/Hetzner. Kubernetes and nomad are two of my core skills, and containerization tools such as docker and lxd/lxc are workloads I run on those clusters. I practice IaaC, with tools such as cloudformation, terraform, ansible, puppet and saltstack. For creating build and deploy pipelines I use various CI/CD tools, including Jenkins, maven, gitlab CI, circle CI, jenkins. I'm experienced in network design and security, linux administration and DevOps services for AWS/GCP/Digitalocean/Linode. A typical workday for me consists of taking care of production linux systems, monitoring the various server fleets I am responsible for, and make sure the systems are secure from attackers.

    Email Wizard, Technician & Marketer with 18 years of experience. I can get your email into the inbox of your list. Period. No matter if it's a cold or warm email. No matter if the list is double opt-in or not. No matter if it's a 10k send or a 10M send. No matter what your offer is (within the legal boundaries of course). I will take your email to your list's inbox and bring you such sales and leads that it will skyrocket your business like Elon's starship. __________________________________________________________________________ ++IMPORTANT++ I am off my desk often and Upwork messages can get lost. If you don't get a reply within 24 hours, or you want to reach me faster: Write to me on Telegram, it's @normathens. ___________________________________________________________________________ I build State Of The Art Self Hosted Email Systems that deliver my clients' emails to the main inbox with a 95-100% rate generating unbelievable leads and sales. Those systems are unlike anything you have ever seen. It's like having your own Mailchimp + Sendgrid + Amazon SES on steroids, all of it for yourself. Usually my client's get 500%+ ROI with the email systems within the first couple of email blasts. - Email service provider doesn't allow you to send your content? - With my system, there is just one person who controls what you send. You. - Your emails are going to Spam instead of Inbox? - Leave the Spam placement headache to your competitors and enjoy the 95-100% inbox placement that my systems provide. - Your opening rates drop after a few sends? - Get your rates back to 30-60% and beyond with AI-powered deliverability algorithms that are under the hood of my systems. If you have ever sent an email to your clients/subscribers/leads you know how hard it is sometimes to get the result you need (phone calls, subscriptions to your offer, leads, orders of your goods and services). Problem #1 - You can't send your content because the email service provider is against it. Many email service providers forbid a lot of content because they fear you can generate spam complaints. No matter how relevant your leads are they will just not let you send your content to them. SOLUTION - with the self-hosted email system you will be able to send your content to your leads without any restrictions. Problem #2 - Your emails get into Spam instead of Inbox. This is a very common problem, and it can have many reasons, from bad IP and domain reputation to complaints and many others. SOLUTION - With my self-hosted systems you get High IP and Domain reputation, you get a "Trusted" position at the main ESPs (Gmail, etc.) so your emails will finally lend into the inbox and get you the result you need. Problem #3 - Emails get into the inbox first but they start to fall into the spam after 1-2 sends. That's a common problem; you must follow a certain strategy to avoid that. Beginning with your list segmentation and ending with how your email servers are set up to avoid that. SOLUTION - My email systems have algorithms under the hood to prevent you from losing your email reputation, so the emails are getting into the inbox every time. Problem #4 - Spam complaints ruin your email servers or your email account gets blocked due to complaints. SOLUTION - There is a certain strategy that reduces the complaints on your emails by 80-90% that I teach to my clients. 90% of email campaigns fail or bring much less results than expected and I know every reason why and how to fix it. If you want to get your Email campaign to the next level, you came to the right person. Ready to get your Email System up and running? Let's chat.
