About Rohan Singh Rajput
As a Senior Machine Learning Engineer, I specialize in building scalable ML systems that translate product vision into measurable impact. Over the last 7+ years, I’ve led the development of production-grade recommendation engines, LLM-based systems, and personalization platforms across health tech, media, and AI product companies.At Spotter, I currently lead AI and MLOps initiatives—architecting multi-tenant LLM pipelines with OpenAI, LLaMA, and DeepSeek, building low-latency APIs with FastAPI and TypeScript, and driving feedback loops with robust monitoring tools on Databricks and AWS. Previously at Headspace, I designed and deployed personalized content recommendation systems that boosted user engagement by over 5%, while implementing real-time A/B testing and retraining frameworks on SageMaker and Databricks.From streaming to healthcare, I’ve consistently delivered results through deep technical ownership, combining my expertise in Python, distributed systems, and DevOps with strong cross-functional collaboration. My work has been featured in patents, international journals, and global AI conferences—bridging research innovation with business outcomes.I’m passionate about building intelligent systems that adapt and scale, and I’m always exploring new ways to apply machine learning to solve real-world problems.
