About

AI/ML Engineer with a strong foundation in Electrical and Electronic Engineering, specialising in building production-grade Generative AI and agentic systems. I've shipped AI features used by 200,000+ users, filed 3 patents, and architected multi-agent pipelines — spanning LangGraph, LLMs, fine-tuning, and cloud infrastructure on AWS and GCP. I thrive at the intersection of research and engineering: translating complex AI capabilities into real business value, communicating across technical and non-technical stakeholders, and owning products end-to-end from proof of concept to production deployment. Currently building agentic AI solutions at Temus. Previously at SAP SuccessFactors, where I led Generative AI feature development and pioneered internal AI Agent adoption. AWS Certified, Databricks ML Professional, and always learning.
