• Secure Cloud Application Architecture (AWS EKS & Serverless), Led the design and implementation of security best practices for a critical financial application deployed on AWS EKS and serverless (Lambda) infrastructure. This included network segmentation, least privilege IAM policies, secrets management (HashiCorp Vault integration), and continuous security monitoring, resulting in zero security incidents post-implementation.
• Enterprise OIDC Authentication Service (Nest.js & Azure AD), Architected and built a centralized OIDC authentication module in Nest.js, integrating with Azure AD for a suite of internal and client-facing applications. This standardized user authentication, improved security posture, and simplified identity management across serverless and containerized environments.
• Dynamic Content & CRUD Generation Engine, Developed a powerful internal toolkit featuring a custom DSL and templating engine (using Hygen and custom scripts) that enabled developers to rapidly generate fully functional CRUD modules and dynamic landing pages, reducing boilerplate code by over 60% and accelerating feature delivery.
• BI Platform with Granular Permissions, Designed and implemented a full-stack business intelligence platform providing customized data dashboards, role-based access control to sensitive metrics, interactive charts, and exportable insights, empowering non-technical users with self-service analytics.
• Immersive VR E-learning for National Programs, Developed a pioneering Unity-based immersive learning experience for industrial training programs, focusing on interactive simulations and complex skill development, which received positive feedback for engagement and knowledge retention.
