Developed secure RESTful APIs in Java (Spring Boot) with JWT-based authentication and role-based access control. Integrated seamlessly with React flows for secure media and zone operations. • Built a fault-tolerant License Plate Recognition (LPR) pipeline using retry logic, request deduplication, and cancellation handling. Improved fetch reliability by 40% and reduced UI race conditions. • Enabled real-time updates across the app using STOMP over WebSocket, delivering instant camera, LPR, and heartbeat updates to the frontend with near-zero latency.. • Built an intelligent blink optimization system for 2,000+ heartbeat nodes. Filtered visible nodes via map viewport and applied randomized sampling, reducing state updates by 95% and rendering load by ~85%. • Created an adaptive media polling system, dynamically adjusting fetch intervals based on image delays to minimize UI stalling and stale data. • Designed optimized Spring Data JPA queries for time-sensitive media, snapshot, and zone data. Achieved fast, scalable backend access to support live dashboards and camera views. • Used Spring’s @Async and @EventListener for decoupled, multi-threaded backend workflows—handling image capture, PTZ actions, and S3 uploads without blocking API responses. • Modernized the UI using React.js and Redux, implementing lazy loading, modular components, and state pruning to reduce load times by 20% and improve performance. • Ensured robust input validation using Hibernate Validator (JSR-380) and centralized error handling via @ControllerAdvice, with full coverage of edge-case and null scenarios. • Built CI/CD pipelines in GitHub Actions to automate builds, testing, and staging deployments. Integrated with S3 and EC2 for packaged release management. • Enabled zero-downtime deployments with Jenkins and GitHub Actions, supporting artifact validation, environment configs, and seamless version rollouts.

1)React for Frontend : Assist in supporting interactive UIs with reusable components, managing state using Redux/Context API, and optimize performance with React Hooks. 2)Node.js & Express.js for Backend – Creating RESTful APIs, handle authentication with JWT/OAuth, and optimize backend logic for scalability. 3)Database Management – Use MongoDB (NoSQL, Mongoose) or PostgreSQL (SQL, Sequelize/Prisma) for efficient data storage and retrieval. 4)API Integration & Security – Monitor & Secure endpoints using CORS, bcrypt for password hashing, and validation libraries like Joi/Zod. 5)Deployment & DevOps – Support in deploying frontend on Vercel/Netlify and backend on AWS/DigitalOcean/Railway, using Docker & CI/CD pipelines for seamless scaling.

• Built 15+ responsive interfaces with React.js (JavaScript) and Bootstrap 5, achieving cross-browser compatibility across Chrome, Firefox, and Safari with 1.2-second page load times using Webpack optimization. • Reduced frontend latency from 2.1 seconds to 1.4 seconds via React lazy loading and AWS CloudFront CDN caching for 200+ static assets. • Migrated 3 transaction processing modules from Node.js to Python Flask/Django, increasing throughput by 40% through Gunicorn and ASGI server optimizations. • Engineered Python-based batch jobs using Celery and Redis, reducing daily transaction reconciliation time from 45 minutes to 12 minutes. • Developed RESTful APIs processing 20,000+ daily transactions at 180ms latency with JWT authentication and Redis rate limiting (100 requests/minute). • Automated AWS infrastructure provisioning using Terraform, cutting environment setup time from 8 hours to 55 minutes. • Streamlined CI/CD pipelines with Jenkins and SonarQube, reducing deployment cycles from 6 hours to 2 hours using parallelized testing (1,200+ test cases). • Containerized services with Docker and Kubernetes, eliminating 10 hours/month of deployment effort through rolling updates. • Implemented Prometheus/Grafana dashboards tracking 150+ metrics, resolving 90% of production incidents within 15 minutes. • Delivered real-time fraud detection handling 800+ daily alerts across 10 Agile sprints using Jira/Confluence.

Built scalable React.js applications using modern practices like functional components, React Hooks, and Redux for state management, enhancing code modularity and developer efficiency. • Optimized app performance by implementing lazy loading with React.lazy and Suspense, reducing initial load time by over 35% for large modules and improving UX on slower networks. • Developed and maintained a customer dashboard and admin tool with dynamic routing (React Router) and conditional rendering, resulting in a 28% boost in overall system performance. • Developed and maintained a customer dashboard and admin tool with dynamic routing (React Router) and conditional rendering, resulting in a 28% boost in overall system performance. • Created highly reusable UI components and integrated them with Redux slices and selectors, improving consistency and reducing feature rollout time by 30%. • Collaborated in an Agile team to refactor legacy class components into modern hook-based functional components, cutting down unnecessary re-renders and improving response time by 22%

Developed responsive web interfaces using HTML, CSS, and vanilla JavaScript, improving accessibility for engineers accessing dashboards on industrial tablets and desktops. • Built interactive dashboards to display production metrics using Chart.js, allowing plant supervisors to monitor real- time operational data visually. • Created reusable UI components, including forms, tables, and modals, enabling consistent design and faster UI development across internal tools. • mplemented client-side validation and dynamic form behavior using JavaScript, reducing data entry errors and improving user experience for shift reporting. • Collaborated with backend engineers to consume REST APIs and dynamically render data-driven content such as shift logs, material usage, and machine status on the frontend.
