• Projects:
• Microservices Development for SaaS Product Offerings: Designed (HLD/LLD) and developed microservices in Java to enable banks (Zeta’s customers) to subscribe to SaaS product offerings (e.g., credit card offerings) through a self-serve UX. Responsible for initial high-level and low-level design, coding, integration testing, and integrating services with other Zeta clusters. Technologies: Java/Spring Boot, Redis for caching, Postgres for database management, Kafka for asynchronous communication, AWS, and Kubernetes for deployments.
• Olympus Home Project: Contributed to the development and setup of Olympus Home, a multi-tenant marketplace for tenants to subscribe to various banking offerings. Key contributions:
• Designed RESTful APIs for a single source of information for 2000+ tenants, improving service availability by refactoring existing code. Implemented filtering, sorting, and pagination using Hibernate Queries to enhance user experience and server performance.
• Optimized resource consumption by implementing Kubernetes Resource Controller Framework. Developed Java-based Kubernetes Custom Controllers for managing tenant resource lifecycles (authentication, database resources) as part of their subscription.
• Kubernetes Custom Resource Operators: Designed and developed Kubernetes custom resource operators using Java Spring Boot and Java Operator SDK. These operators automate tenant resource creation and updates via Custom Resources. Also implemented mutating/validating admission webhooks for customizing and validating the applied resources.
• Custom Authorization Framework: Developed a custom authorization framework based on RBAC and HMAC authorization for the microservices, ensuring secure access and proper integration.

• Worked on designing (HLD/LLD) and coding a bunch of Microservices in Java from scratch, that enable a Bank (Customer of Zeta) to subscribe to a SaaS Product Offering of Zeta (Eg: Credit card offering). This SaaS Product can be subscribed in a self-serve manner via a UX. Performed the initial high-level and low-level design for multiple backend orchestration microservices, coded those microservices from scratch, wrote integration tests, and integrated our services with other clusters/microservices of Zeta. Used
• Java/Springboot for development, Redis for caching, Postgres for database, and Kafka for async communications in between the services, AWS and Kubernetes for deployments.
• Worked on the setup and development of Olympus Home( a multi-tenant marketplace for tenants to purchase, subscribe and get onboarded to various banking offerings by Zeta )
• Responsibilities involved:
• 1. Designed Restful APIs providing single source info of 2000+ tenants @ Zeta. Managed tenant metadata and continuously improved service availability by refactoring exciting codebase.
• Employed filtering, sorting, and pagination using Hibernate Queries, ensuring optimal user experience and server performance.
• 2. Streamlined resource consumption by tenants via K8’s Resource Controller Framework. Adopted the Java version of K8s Custom Controllers, for managing the lifecycle of resources used by a tenant. Developed several RCs for managing authentication and database resources used as part of a tenant subscription
