Hello, I'm Sandeep Kumar Mahto.

AI/ML Engineer & Cloud-Native Developer

I build intelligent systems, RAG pipelines, and predictive models. Oracle Certified Generative AI Professional focused on turning complex data into scalable, production-ready applications.

// about_me

I am a Computer Science undergraduate (B.Tech '26) specializing in Generative AI, Machine Learning, and Python Backend development. I have hands-on expertise in building end-to-end ML lifecycles, from data preprocessing and feature engineering to model deployment and MLOps.


Currently, I lead AI data generation initiatives and manage remote technical workflows, bridging the gap between creative strategy and technical execution. I am passionate about prompt engineering, vector search, and cloud-native development on Oracle Cloud Infrastructure (OCI).
