•Spearheaded the design and development of a cloud-native web application ecosystem using TypeScript, React, and Node.js with modern architectural patterns, which improved overall system performance and stability and reliably supported over 10K concurrent users across globally distributed regions.

•Engineered and shipped reusable, scalable frontend and backend modules, implementing efficient state management, caching, and pagination to enhance responsiveness, reduce latency, and improve overall user experience.

•Collaborated with cross-functional teams, including product managers, designers, and data/ML engineers, to integrate AI-driven features such as personalized recommendations and predictive analytics, enabling actionable insights and higher user engagement.

•Integrated REST/GraphQL APIs, third-party services, and background jobs while setting up automated build, test, and deployment pipelines (CI/CD) with GitHub Actions and Docker/Kubernetes, achieving 3x faster release cycles and safer rollouts.

•Optimized web performance by profiling rendering, network, and database layers, reducing page load and Timeto Interactive, minimizing bundle size, and implementing lazy loading strategies, resulting in significantly faster navigation and improved responsiveness under heavy traffic.

•Strengthened application security posture by following OWASP guidelines, implementing secure authentication/authorization flows, encrypting sensitive data at rest and in transit, and ensuring compliance with GDPR and other privacy and security regulations.

• Designed and implemented high-performance full-stack web applications on Google Cloud Platform using TypeScript, React, and Node.js, ensuring seamless communication between frontend clients, backend APIs, and third-party services.

•Improved system reliability and scalability by architecting modular, reusable frontend components and backend services, contributing to a 20% increase in successful user sessions and reduced error rates across the stack.

•Led the development of geospatial features and visualizations for real-time tracking and analytics over 1M+datapoints, building REST/GraphQL APIs and interactive map UIs with Google Maps and related geospatial services.

•Collaborated closely with backend, frontend, and UX teams to define efficient API contracts, data models, and error-handling strategies, significantly improving cross-team delivery speed and reducing integration defects.

•Successfully migrated legacy monolithic applications from jQuery/JavaScript and tightly coupled server logic to React-based SPAs and TypeScript-powered microservices, improving maintainability, testability, and reducing production incident rates by 15%.

• Enhanced CI/CD pipelines by introducing automated unit/UI/API testing, build versioning, and containerized deployments via GitHub Actions/Jenkins and Docker, enabling continuous integration and iterative delivery.

• Assisted in building and maintaining client-facing web applications, focusing on implementing new features and UI pages using JavaScript/TypeScript and modern frontend frameworks.
• Collaborated closely with backend and frontend teams to integrate RESTful APIs, improving overall functionality, data consistency, and error handling across the stack.
• Developed basic data display, filtering, and reporting views on the frontend, along with simple backendendpoints and queries, to power real-time analytics dashboards and help users track key KPIs more effectively
