    A Top-Rated, Expert-Vetted VoIP/Software engineer with over 20 years of experience. My experience ranges from Asterisk/FreePBX phone systems, SMS messaging, Linux operating systems, to network administration. I believe you deserve a more professional, reliable, and personalized business experience, and I bring that mindset to every project. Whether I’m developing top-secret code for Lockheed Martin, or AI telephone agents for Nomo, or creating privacy-first communications for Mecca Hosting, Inc, or designing secure, high availability Asterisk systems for TeleConnx Inc., or handling difficult troubleshooting tasks, I always commit myself to the same standard: creative, client-first solutions and efficient, high-quality work, completed in a fraction of the time. I have a passion for transforming mundane phone interactions into exciting customer experiences, and I lean on decades of experience to create solutions that others would find impossible. In short, I can make your telephone system do pretty much anything, including turning on your coffee maker in the morning. I look forward to working with you!

    Hey, I'm James. I've been a self-employed business network and server admin for 21+ years. I've worked with all flavors of Linux and Windows for some of the best businesses in the country. My average customer that I've worked with has been with me over 10 years. I specialize in analyzing current infrastructure and determining the needs of my clients then providing a written plan to correct any issues and protect the business systems from hackers and cryptolockers. In one of my recent projects, I consulted with a six billion dollar, publicly traded company to completely redesign their infrastructure to have redundant firewalls, VMWare host servers, leased fiber lines directly to Amazon AWS with a VPN backup over a regular Internet circuit that would automatically fail over in case of any circuit issue. The vmware servers would auto migrate the guests in the case of overload or host server failure. All power systems were redundant with two powersupplies for each piece of equipment. At the end of this project, we had reduced their monthly cost of management by over 25,000 per month and reduced their server load from over 20 servers to just 8 servers. When you hire me, here's what you can expect: 1. First, click the invite button to invite me to your job. 2. Once everything is accepted, I'll jump on the phone or a zoom with you 3. We'll go over the details of the job and I'll ask questions to drill down to the specific goals you want to accomplish. 4. I'll provide you with a high level written plan to address your goals along with expected time needed to complete your project. 5. When we agree on the timeline and process, I will execute the plan. So, if this sounds good, just click the "invite" button and we can start.

    My name is K.B Asare and i have nearly 10 years experience in the IT industry. In the past 8 years I narrowed that experience and expertise to cover many aspects of enterprise networking. I have in the past 6 years have primarily worked in the administration and management of Linux, Redhat/ Centos 7 servers, as well as Windows systems administration. I have industry certifications in Network+ and Security +. This solid foundation has allowed me to be able to manage, troubleshoot, configure and secure many aspects of a company's physical and virtual networks. Furthermore, I have administered Linux/Windows servers physically and virtually either in the cloud, as in the case of AWS/Azure or virtually using VMWARE. I have build servers from scratch in a physical or virtual environment and in some cases using a PXE server. At the browser or using Putty, I can also do basic management, troubleshooting and configuration of different brands of routers and switches including some Cisco. In summary, in an environment where a company has either 50 or 1500 Linux/Windows servers both physically or virtually, i can administer those systems as well as setup manage and troubleshoot network components like routers and switches to maximize productivity and minimize downtime for the company/team. Having worked closely with the DevOps team in my current environment, I have utilized automation tools like Ansible and puppet. I helped the team build docker containers and loaded images, as well as Kubernetes nodes. Aside from my technical know-how, i work well in a team setting, require very little supervision and take initiatives where needed. I am a fast learner with a tireless work ethic. If there is an issue or subject matter i am not familiar with, you can rest assured that i will endeavor to acquire the knowledge i need to make a positive impact for the company or team to assist in their Linux administration and networking needs. Thank you.

    With 14 years of industry experience, I began my career as a web developer, specializing in PHP with Joomla and later mastering WordPress, including WooCommerce. I have a deep understanding of database optimization to ensure peak performance. About eight years ago, I transitioned to Linux Server Administration, developing expertise in malware removal, including Blackhole exploits, Pharma hacks, redirection hacks, phishing hacks, and spoofing. I have successfully cleaned websites to secure Google approvals that clients were previously unable to obtain. This involved deep cleaning of codes and fixing issues that even top scanning tools did not detect. I started working with control panels like Plesk, WHM (CPanel), and VestaCP, before devising a fast and secure LEMP solution. This solution integrates advanced security measures, whether using CloudFlare or not, with tailored code snippets that enhance security and optimization, significantly improving site performance. I have extensive experience managing WordPress blogs and WooCommerce stores, providing comprehensive consultations from server selection to optimization, ensuring they can handle significant traffic loads, even during promotions, without encountering the white screen error in shopping carts. For Aapanel, I transformed it into a sophisticated product through meticulous configuration and research, tailoring it to meet user needs and ensuring responsive service. My skills also include performing security audits, conducting load stress tests, and monitoring and tracking server requests. I handle debugging, log management, and automate alerts. Additionally, I offer custom backup solutions for servers and websites, managing them across S3 buckets, Git repositories, Google Drive, or Dropbox, and I specialize in API integrations. I hold a diploma, a BTech, and an MBA in Information Technology, and have obtained numerous professional certifications from prestigious institutions including IBM, Cisco, Fortinet, Google, Oracle, Amazon, and I am also an Aviatrix certified ACE Engineer. My profile features an array of endorsements and testimonials from clients, all attesting to a 100% success rate in project delivery - feel free to review these testimonials to see what they have said. I am a member of respected associations such as NASSCOM, TiE, and CII, which keep me connected with industry trends and innovations. My role mandates a continuous pursuit of knowledge, ensuring that my clients' systems are always up to date and optimized. My problem-solving skills are frequently highlighted by clients, with one recent example where a client stated, "Before you, I conducted 10 interviews and none were able to grasp the issue, yet you not only understood it but also resolved it swiftly." My expertise has led clients to entrust me with managing their teams and servers, leading to enhanced team performance and product deliveries well ahead of deadlines. Working primarily in PHP/MySQL and the Laravel framework, I utilize tools such as VSCode, Git, NeoVim, and tmux. As a console enthusiast and productivity hacker, I focus on simplifying processes and extensively write automations to enhance efficiency. 🚀 Are you ready to take your project to the next level? Let’s collaborate and make it a reality! Over the years, I have developed a robust skill set across a diverse range of technologies and platforms. This includes expertise with various project management and collaboration tools such as Trello, Asana, Bitrix, and Basecamp; communication tools like Slack; and productivity suites like Google Apps and Zoho.

LINUX SYSTEM ADMINISTRATORS FAQ

What is Linux system administration?

Linux is an open-source operating system (OS) that’s easier to secure, update, and maintain than closed-source offerings such as Windows. Because Linux is the most popular OS for servers, Linux system administrators have access to a lot of developer resources.

Here’s a quick overview of the skills you should look for in Linux system administration consultants:

  • Linux system administration
  • Linux distros (e.g., Ubuntu, Unix)
  • IT automation
  • Database technologies (e.g., MySQL, PostgreSQL)
  • Systems languages (e.g., C, C++, Golang)
  • Back-end languages (e.g., Java, PHP)
  • Application technology stacks such as LAMP (Linux, Apache, MySQL, PHP)

Why hire Linux system administrators?

The trick to finding top Linux system administrators is to identify your needs. Are you switching from a cloud-based infrastructure to a physical IT infrastructure for the first time? Do you require an admin familiar with DevOps to implement continuous integration and a continuous delivery pipeline? The cost of your project will depend largely on your scope of work and the specific skills needed to bring your project to life.

How much does it cost to hire a Linux system administrator?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.

  • An experienced Linux system administrator may command higher fees but also work faster, have more specialized areas of expertise, and deliver higher-quality work.
  • A contractor who is still in the process of building a client base may price their Linux system administration services more competitively.

Which one is right for you will depend on the specifics of your project.
