About

I’m a Full Stack Developer currently working at Jazz as a Specialist Service Desk Solutions, where I focus on ServiceNow development, cloud applications, and ITSM automation. I design and maintain custom enterprise solutions using Node.js, ASP.NET, and JavaScript, helping improve service efficiency through smart automation and AI-driven workflows. With experience in the MERN stack and TypeScript, I enjoy building modern, scalable web applications that blend great user experience with strong backend performance. Previously, I contributed to projects at West Coast Technologies, JAZZ, and Fiyxer, developing CRM systems, eCommerce platforms, and real-time collaboration tools. I’m passionate about clean code, automation, and continuous learning in AI and cloud technologies. Beyond work, I enjoy mentoring developers, a passion I pursued as Web Development Lead at MLSA Multan. In my free time, I love playing cricket or relaxing with a good cup of tea both help me reset and bring fresh energy to what I build.
