Samrat Saha — Lead ML Engineer

I’m a Machine Learning Engineer based in London with 20+ years of experience building and scaling ML systems across Ads, Retail, AgriTech, and large-scale language and vision models. I started my career close to hardware, working with C/C++ and FPGA-based systems, which shaped how I think about performance, memory, and reliability. Over time, I moved up the stack to large-scale ML platforms, and today I focus on building models and systems that are not just accurate, but deployable, efficient, and reliable in production. Impact & Products Contributed to Krutrim’s first LLM (First Indic LLM) release and benchmarking, strengthening evaluation for large-scale language models. At Cropin, scaled SmartRisk, a precision agriculture platform using satellite imaging to for crop prediction, LULC, sustainability use cases like deforestation, stable burning, impacting agribusinesses, supply chain globally. Delivered AI platforms driving $100M+ business impact in Ads and Retail. Architected and shipped Prism, a visual contextual AdTech platform enabling shop the look showcased at Reliance AGM — combining large-scale CV + ML with product impact. Leadership & Collaboration Built and led agile ML teams, mentoring engineers and aligning cross-functional groups. Partnered with Nvidia, Databricks, and collaborated with startups such as boxx.ai and accio.ai. Supported M&A efforts, including the OnePlay acquisition at Jio. Innovation & Expertise Holder of 4 patents in Computer Vision, NLP, and anomaly detection. Expertise across Recommender Systems, Ranking & Prediction, AdTech, Computer Vision, Deep Learning, Generative AI, and large-scale ML infrastructure. 30+ certifications in Deep Learning, Distributed Systems, and ML Design. I enjoy working at the intersection of research and engineering — building products that scale, deliver measurable outcomes, and create long-term value.
