Linux System Administration PHP API Network Security Virus Removal MySQL Penetration Testing WordPress Malware Removal Internet Security Mail Server Implementation Web Application Security WordPress Plugin Website Security Network Administration Web Hosting
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. Additionally, I'm skilled in email automation, Gsheets and setting up efficient workflows. My technical background also spans Platform.sh, Hugo, Netlify, Git for CI/CD, WP Engine, Vultr, Digital Ocean, Linode, AWS, GCP, Oracle, Godaddy, SiteGround, Bluehost, custom VPNs using OpenVPN, Lara Classified, and custom funnel systems in both Laravel and WordPress.
