Designed and implemented a large-scale REST API with 200+ routes and 60+ database schemas, supporting authentication and authorization. Maintained APIs serving continuous production traffic with active users. Architected a custom Role-Based Access Control (RBAC) system with fine-grained permissions applied across all API endpoints. Applied industry-standard backend design principles, including clear separation of concerns and layered architecture. Implemented Redis-based caching, reducing database load and improving average API response time by 150-200 ms. Decreased initial page load time from 3s to 1.47s. Scaffolded, optimized, and containerized a Jobe-based execution engine for evaluating programming problem submissions, automated testing, and log storage in NoSQL databases. Enforced robust request validation, middleware processing, and Route–Controller–Service-Repository flow.
