Lead Data Engineer with experience cracking interviews at leading global firms including EY, Deloitte, Cognizant, Accenture, Publicis Sapient, EPAM, Capco, Tiger Analytics, and Fractal. I built my data engineering career through disciplined self-learning—without relying on expensive bootcamps—and strategically repositioned my profile in the market. This journey resulted in a 3× compensation growth through focused preparation and effective interviewing. I now help aspiring and transitioning data engineers shorten their learning curve, prepare with clarity, avoid common interview mistakes, and confidently crack high-impact roles.
