Professional Experience

Site Reliability Engineering Intern

WSO2

June 2025 - May 2026

As a Site Reliability Engineering Intern at WSO2, I worked across the Asgardeo cloud identity platform, WSO2 Identity Server and ThunderID opensource identity platform, entering with no prior background in cloud infrastructure and building deep expertise in Kubernetes, Helm, Terraform, and AWS from the ground up. My primary project was extending Asgardeo's existing Azure DevOps CI pipeline to add full AWS deployment support implementing ECR image publishing, PostgreSQL integration, and Secrets Manager configuration enabling a single pipeline to drive multi-cloud deployments. I was also given sole public release ownership of the WSO2 Identity Server 7.2 and 7.3 Helm charts, validating deployments across seven distinct Kubernetes environments. Beyond infrastructure delivery, I independently conducted an end-to-end STRIDE security threat model for Asgardeo's new cloud deployment architecture, identifying 23 threat vectors and developing 18 mitigation strategies that were presented to and fully approved by the Security Architecture Review Board. I designed and provisioned AWS infrastructure (VPC, EC2, MySQL) from scratch to support IS 7.2 testing, executed a database schema migration from MSSQL to PostgreSQL, and contributed an open-source TLS termination feature to WSO2 Thunder using the Kubernetes Gateway API and Envoy, which was merged to main. The internship gave me hands-on ownership of production-grade cloud-native identity infrastructure at a scale well beyond typical intern work.

Key Achievements

Extended Asgardeo's Azure DevOps CI pipeline from scratch to add full AWS deployment support, implementing AWS ECR image publishing, PostgreSQL integration, AWS Secrets Manager, and Terraform-provisioned infrastructure

Took sole public release ownership of the WSO2 Identity Server 7.2 and 7.3 Helm charts, validating deployments across seven Kubernetes environments: Minikube, Envoy, Azure AKS, AWS EKS, RKE2 on SUSE, OpenSearch, and OpenShift

Independently conducted an end-to-end STRIDE security threat model for Asgardeo's cloud deployment architecture, identifying 10 threat vectors across 5 categories and developing 13 mitigation strategies

Presented threat model and mitigation recommendations to the Security Architecture Review Board and Product Leadership, achieving 100% approval of all recommendations

Designed and provisioned AWS infrastructure (VPC, EC2, MySQL) from scratch to support WSO2 Identity Server 7.2 testing, including network architecture and security group configuration

Implemented Agent Identity datasource support in the WSO2 IS 7.2 Helm chart, enabling Helm values-driven database configuration for agent identity-based authentication
