Built full-stack enterprise applications using React, Next.js, NestJS, and PostgreSQL, delivering reusable frontend UI components, modular backend services, and API-driven business automation systems.
Engineered high-performance REST APIs and asynchronous backend processing using Redis and RabbitMQ, reducing API response times by 30% through caching, query optimization, and background tasks.
Applied Repository, Strategy, and Factory design patterns within NestJS services to improve maintainability, extensibility, and separation of concerns across shared business modules.
Led development of an AI-assisted automation platform using OpenAI APIs to analyze client requirements and generate proposal documents with architecture diagrams, effort estimation, and project timelines.
Optimized frontend state management using Redux Toolkit and RTK Query, reducing redundant API calls by 20-25% and improving data consistency across dashboard applications.
Increased unit and integration test coverage from 53% to 86% using Jest, SuperTest, Mocha, and automated CI workflows, improving regression stability and release reliability.

Built responsive frontend features and reusable UI components for dashboard applications, collaborating closely with backend teams to deliver API-driven workflows.
Developed and maintained Node.js and Express.js REST APIs, improving backend reliability through modular service design and clean separation of concerns.
Optimized MongoDB queries and implemented secure JWT-based authentication flows for internal application modules.
Integrated Swagger / OpenAPI documentation and supported backend test coverage using Jest, Mocha, and SuperTest for stable release cycles.
Worked with Docker, GitHub, and CI/CD pipelines to streamline development handoffs and deployment readiness.

Developed responsive React dashboards using ApexCharts, implementing debouncing, request throttling, and optimized rendering techniques to improve responsiveness across data-intensive interfaces.
Built RESTful APIs using Node.js and Express.js, optimizing MongoDB queries and integrating Google Calendar APIs to automate appointment scheduling processes.
Integrated AWS S3 for secure document storage and deployed backend services on AWS EC2, improving reliability and streamlining file management operations.
