Hello! I'm Tech Engineer DevOps Fan Full-Stack Dev
I am a part-time Computer Science student at Goldsmiths, University of London, studying remotely while gaining hands-on experience in technical support, Linux server management, cybersecurity, and full-stack development. I founded and develop dnstoolbx.com, an all-in-one DNS and network toolbox built with Python, Flask, SQLite, and modern web technologies, showcasing my backend, API, cloud deployment, and AI integration skills.
As a Front-End Developer at WebPhoenix.eu, I delivered responsive, user-friendly websites using HTML, CSS, JavaScript, jQuery, Bootstrap, and UX/UI design principles.
Currently, I work as a Technical Support Specialist at IPHost, resolving hundreds of technical tickets related to Linux server administration, web servers, DNS, and mail systems. Additionally, I contribute to full-stack development by building and deploying internal web applications using Python, Flask, HTML, CSS, JavaScript, jQuery, and Bootstrap, integrating with cPanel/WHM APIs, and creating intuitive interfaces that allow the team to analyze data, automate workflows, and significantly reduce the time required to resolve specific cases, streamlining operations and improving overall efficiency.
I am passionate about AI, DevOps, cloud engineering, cybersecurity, and automation, building secure, scalable, and efficient solutions that solve complex technical challenges.
