• •Implemented role-based access control (RBAC), reducing unauthorized access issues by 30% and strengthening overall system security.
• •Configured dynamic module enablement, including service assignments, milestone tracking, and capacity management, improving process efficiency by 25%.
• •Automated hierarchy updates and integrated email notification services, reducing manual intervention by 80% and improving communication turnaround time.
• •Optimized backend performance by enhancing API response times by ~74% on average (measured across 8 JMeter test runs) through query tuning and implementing SQL indexing strategies.
• •Conducted performance testing using JMeter, identifying bottlenecks and improving system throughput by 140% under load conditions.
• •Developed and supported basic frontend components using HTML, CSS, and Angular, improving admin usability and reducing task completion time by 15%.
• •Collaborated with QA and business stakeholders to resolve defects, reducing production issues by 25% and improving overall system stability.

Built as a Modular Monolith — the app deploys as a single unit but is internally divided into persona-based modules (Learner, Manager, Admin), each following its own N-Tier layered structure for clean separation of concerns and scalability.

• •Developed a centralized digital learning platform integrating multiple learning systems using C#, .NET, and REST APIs.
• •Architected the codebase as a Modular Monolith with per-module N-Tier Architecture — each persona (Learner, Manager, Admin) organized into its own module with dedicated Presentation, Business Logic, and Data Access layers, ensuring clean separation of concerns and scalability within a single deployable unit.
• •Implemented role-based access control (RBAC) to ensure secure and user-specific functionality.
• •Built features for course assignment, learner progress tracking, and automated notifications, improving training efficiency.
• •Designed scalable backend services for bulk data processing, enhancing system performance and reliability.
• •Collaborated with stakeholders to enhance reporting and analytics capabilities.

• •Developed modules for bulk order processing, digital measurement capture, and multi-level approval workflows using C#, .NET, and MSSQL, handling 1000+ orders/day.
• •Designed and implemented RESTful APIs to manage the end-to-end order lifecycle from measurement to production, improving process efficiency by 30%.
• •Built backend validation logic and processing workflows, reducing data errors by 25% and improving operational accuracy.
• •Delivered scalable system enhancements to support domestic and international operations, improving system reliability and throughput by 20%.

• •Developed backend APIs and database logic using C#, .NET, and MSSQL to support complaint logging, routing, escalation, and resolution tracking, handling 500+ requests/month.
• •Implemented workflow automation to route issues based on business rules, reducing manual intervention by 60% and improving resolution time.
• •Optimized database performance through query tuning and indexing strategies, improving response time by 35%.
• •Maintained high code quality standards, resolving QA defects and reducing production issues by 25%, ensuring stable and reliable releases.
