Jashan S. — Engineering Manager

As an Engineering Manager at Best Buy, I bring over 7 years of experience leading the development of high-traffic websites and mobile applications, specializing in full stack development with a focus on leveraging AI and machine learning to deliver personalized customer experiences. My most recent project involved developing personalized home screens and home pages for both web and mobile apps, providing customers with tailored deals and product recommendations by utilizing AI and ML. I lead cross-functional teams, including data scientists, engineers, and product managers, to build and deploy end-to-end solutions that drive engagement and conversion. My expertise spans front-end technologies like React for web and React Native for mobile, and I’ve successfully managed iOS and Android development projects that scale to millions of users. I’ve also integrated GraphQL to optimize data handling and ensure efficient communication between the client and server. With a strong background in quality management, I ensure the highest standards of performance, scalability, and security across all digital platforms. My previous experience as a Senior Quality Assurance Engineer Lead and Project Manager provided a solid foundation in delivering reliable, high-quality software solutions. Equipped with a Master of Science in Business Analytics from the University of Washington, I apply data-driven decision-making to all aspects of development and strategy. I’m excited to bring my expertise in AI, ML, mobile development, full stack technologies, and quality engineering to roles in program management and quality leadership, helping organizations innovate and scale their technology solutions.
