At TCS, I shipped full\-stack features across Python, Java, and JavaScript; built 3 Power BI dashboards that replaced manual reporting for business stakeholders; developed R Shiny applications for self\-serve analytics; and owned end\-to\-end QA cycles — functional, regression, API, and integration — maintaining zero critical escapes across four consecutive release cycles\. My MSc covered AI, Machine Learning, NLP, Cloud Computing, Cybersecurity, and Advanced Databases\. I hold 10 professional certifications, including Microsoft Azure Fundamentals, Power BI, Agile, Git, and Cybersecurity, and regularly use AI tools \(Copilot, Claude, ChatGPT\) to accelerate delivery\.
