I specialize in setting up the best hosting environment for (high-traffic) WordPress / Laravel / CodeIgniter / PHP sites that would have the fastest possible speed on the server-side. For example, most of the servers deployed by me have the following features. * Brotli - to improve the speed of all pages by compressing them efficiently. * TLSv1.3 - to reduce the RTT (round trip time) while establishing the SSL connection. * webp support - to reduce the size of the images. In addition, I could implement the best practices to have a high level of security! I can also help with improving the development workflows. Projects: ---------- I have been contributing to a few open-source projects that are being used by a growing number of users, sites, and servers worldwide. I have published three WordPress plugins (in the official WordPress repo), targeting high-traffic websites and staging sites. You can find me helping others in multiple places, including in the official WordPress forums and ServerFault / StackOverflow. I am one of the top contributors in ServerFault for the tag Nginx. I have two active blogs sharing my insights on WordPress and the Web in general. I can provide all the relevant links during the interview. Education: ------------- I have no formal education related to what I do now. I am a self-taught Server Admin, DevOps, Web Developer, VA, or whatever you name it. I am a jack of all trades and a master of servers. I keep learning something new every week. Hourly Rate: --------------- My average hourly rate is USD 30 per hour. It varies depending on various aspects of a project. For example, I have a reduced hourly rate for non-profits. Availability: -------------- I am in GMT + 5:30 timezone. I am usually available online for a few hours between 2 am and 2 pm GMT during weekdays. I always look for exciting projects and complicated issues to solve!

I build practical private AI and automation systems that small businesses can actually use. My focus is self-hosted AI, Linux/Docker infrastructure, n8n workflow automation, Ollama, Open WebUI, LibreChat, VoIP/Asterisk systems, and small business workflow automation. Earlier in my career, I owned a small technology company called Data Deployment Solutions, where I built database-driven internal business applications for local businesses using PHP, Apache, MySQL, HTML, JavaScript, and CSS. These were practical B2B systems running on in-house Linux/LAMP servers, accessed by office staff through web browsers on the local network. I also built business phone systems using Asterisk and Linux server hardware. Today, I help clients with modern versions of that same kind of practical business technology: • Install and configure Ollama, Open WebUI, LibreChat, and private AI tools • Build or troubleshoot n8n automation workflows • Set up Linux/Docker servers and Docker Compose stacks • Connect self-hosted AI models to business workflows • Build private AI assistants, RAG/knowledge-base systems, and internal automation tools • Connect AI systems to business documents, internal knowledge bases, APIs, and workflow tools • Troubleshoot small business VoIP/Asterisk systems • Build internal web applications, dashboards, and database-backed business tools I am especially useful when you need someone who understands both the technical side and the small-business workflow side. I do not just install software — I help you think through how the system should actually be used. Good starter projects for me include: • Set up Ollama and Open WebUI on a Linux server • Fix a Docker Compose stack • Build an n8n workflow that calls a local AI model or API • Prototype a private AI assistant or RAG/knowledge-base system • Troubleshoot an Asterisk/VoIP setup • Automate a repetitive business process • Build or improve an internal business web application My goal is to build useful, maintainable systems that solve real problems. I keep projects practical, honest, and human-in-the-loop.
