Lead Data Scientist at Happiest Minds Technologies

About

With over 8 years of experience in data science, I specialize in building scalable machine learning solutions and driving product innovation across industries. My career includes the successful execution of numerous AI/ML projects—from concept to deployment—focused on solving complex business problems through data-driven decision-making. I’ve led and managed AI/ML teams on initiatives that achieved a 30% increase in productivity and a 25% reduction in time-to-market for key products. I’ve worked closely with cross-functional teams—including product, engineering, and business stakeholders—across geographies to deliver high-impact solutions. My cloud expertise (AWS, Azure) has enabled the seamless deployment and scaling of AI systems in real-world environments. In today’s fast-evolving AI landscape, I take pride in being a fast adopter of emerging technologies. Beyond technical capabilities, I bring a strong track record in leadership and adaptability—navigating ambiguity, mentoring teams, and aligning technical execution with business goals. Known for a pragmatic yet forward-thinking mindset, I thrive where data meets purpose. I enjoy exploring the intersection of technology and psychology, especially how people interact with intelligent systems.
