Spearheaded frontend architectural migration for customer and partner portal modules to React.js, Angular, TypeScript, and Tailwind CSS, improving responsiveness and cross-device rendering performance by 35%. Rebuilt high-volume user workflows (account onboarding, dynamic profile management, content search, operational reporting, and admin controls), reducing average task completion time by 28%. Developed and modernized backend microservices with Java, Spring Boot, Node.js, Express.js, and REST APIs, improving maintainability and cross-team reusability by 40%. Implemented Apache Kafka producers and consumer groups using Java concurrency (ExecutorService, CompletableFuture) for high-throughput parallel execution. Optimized PostgreSQL and MongoDB access layers using indexes, query execution plans, and connection pooling for a 30% improvement in analytics dashboard and audit log performance. Containerized workloads with Docker and Kubernetes (EKS), establishing autoscaling and health chec

Engineered robust backend RESTful APIs with Node.js and Express.js for enterprise account records, multi-level ticket workflows, approval hierarchies, and automated case tracking. Implemented asynchronous, event-driven architectures using Redis and messaging patterns to decouple status updates, notification delivery, and background job scheduling. Designed responsive client interfaces with React.js, JavaScript (ES6+), and Tailwind CSS for dashboards, audit logs, and workflow forms. Built PostgreSQL schemas and complex SQL queries alongside MongoDB collections to resolve reporting and analytics bottlenecks. Added server-side validation, RBAC, and session security with JWT and HTTPS best practices to prevent unauthorized data access. Contributed to Docker-based CI/CD pipelines using GitHub, Jenkins, AWS (EC2, S3, CloudWatch), achieving a 15% reduction in release defects. Developed unit and integration testing using Jest and Postman and collaborated in Agile/Scrum with JIRA and peer code
