About Me
Hi, I'm Jomar Cotejo 👋. I'm an IT Support Specialist with over 3 years of experience delivering reliable technical support across commercial, government, education, and media environments 🖥️. My expertise includes Windows 10/11, Active Directory, Microsoft 365, device deployment with Intune, and supporting AV systems.
I've worked with organizations like NSW State Emergency Service, WIN Television, and TAFE NSW, providing Level 1 and Level 2 support 💻. I'm known for clear communication, strong documentation, and the ability to prioritise and resolve issues efficiently in fast-paced business environments.
Beyond my IT support work, I'm passionate about expanding my skills in web development and automation 🚀. I'm currently building personal projects with JavaScript, React, and TypeScript, combining my systems knowledge with modern development practices to create practical solutions.
