## About

Backend Software Engineer at Visa specializing in MLOps, cloud\-native architecture, and distributed systems\. I currently focus on architecting and building Visa's next\-generation Machine Learning Platform to AWS EKS, building a cloud\-agnostic Kubeflow stack designed to serve 1,000\+ data scientists\. My expertise lies in developing high\-performance backend services in Golang and Python, designing robust multi\-tenant isolation models, and implementing complex identity federation \(OAuth2/OIDC\) across distributed network boundaries\. Recent highlights include: • Architecting a comprehensive Kubeflow ecosystem \(Notebook, TrainJob, Pipelines, KServe\) on AWS EKS, implementing a custom identity federation chain for secure, zero\-secret workload isolation across multiple AWS accounts\. • Integrating NVIDIA DGX H100 clusters with Run:ai orchestration via custom FastAPI services to streamline GPU workloads\. • Building real\-time monitoring and resource allocation pipelines that reduced failed job submissions by 35% and improved backend API response times by 60%\. I am passionate about tackling complex resource constraints, platform security, and building scalable, developer\-first infrastructure from the ground up\. Top Skills: Golang • Python • Kubernetes & AWS \(EKS\) • Kubeflow & MLOps • Distributed Systems • Identity & Access Management \(OIDC/OAuth2\)
