About

Production Support Analyst with over 3 years of experience ensuring application stability, resolving high-priority incidents, and performing root cause analysis in enterprise environments. At Infosys, I worked in L2 support role where I closely collaborated with cross-functional teams to monitor systems, optimize database performance (Oracle & SQL Server), and automate tasks using scripting. My strong technical foundation is backed by hands-on experience in Unix/Linux systems, job scheduling tools like SAP Redwood, and ITIL-based incident management using ServiceNow. I’ve contributed to process improvements that reduced system downtime and increased operational efficiency. Alongside my professional experience, I pursued a postgraduate degree in Web Development from Conestoga College, where I gained knowledge of the MERN stack (MongoDB, Express.js, React, Node.js) and built projects such as e-commerce platforms and blog systems. This development experience enhances my ability to automate, troubleshoot, and communicate effectively with dev teams. I'm now seeking opportunities in Application Support, or SRE focused roles where I can leverage both my support experience and technical background to maintain and enhance critical systems.
