About

I am a Software Development Engineer (ASDE-2) at Publicis Sapient, working on enterprise-scale cloud-native platforms for a major UK bank serving 25M+ customers. I specialize in Java-based distributed backend systems, cloud infrastructure, and DevOps automation, with hands-on experience across GCP, Kubernetes, Terraform, Istio, Jenkins, Apigee, Harness and Backstage. My work focuses on building high-availability, low-latency services used daily by tens of thousands of users. Beyond core engineering, I actively work on Generative AI, Agentic AI and RAG systems, mentoring teams on LangChain, CrewAI, and agentic architectures, and contributing to internal AI platforms used in real production workflows. I enjoy solving problems end-to-end, from system design and architecture to production deployment and observability, with a strong focus on reliability, scalability, and developer experience.
