Worked on development of retirement and related business applications and other product pages. Built front-end features using Angular/TypeScript and responsive UI practices, including internationalization (i18n) for multi-language client pages. Integrated REST APIs and managed centralized state with Redux in client applications. Implemented reusable UI components and mobile interfaces through dedicated interfaces for the mobile application. Also contributed to back-end and service work: designed secure, performant REST APIs with attention to reducing latency and improving data handling. Developed microservices architecture using Spring Boot, with service-to-service communication via REST/gRPC and asynchronous messaging using Kafka events. Integrated Elasticsearch for fast search and indexing of large datasets. Containerized applications with Docker, deployed and scaled on Kubernetes, and monitored services in production using Grafana dashboards. Wrote unit tests to improve code qualit

Developed a real-time chat application with JWT-based authentication and WebSockets, including live typing indicators and low-latency messaging. Built AI-powered document intelligence UI experiences (Angular/TypeScript, REST, WebSockets) with real-time progress indicators for high-capacity file uploads (PDF, images, CSV). Implemented polling mechanisms for AI processing status and transformed raw AI output into interactive tables with sorting, filtering, and pagination. Contributed to mobile and web features such as building social media functionality with JWT authentication and real-time interactions, image uploads, and functional post-creation experiences. Implemented performance optimizations like lazy loading, memoization, and image caching to reduce load times on older devices. Added secure authentication flows and improved overall UX for responsive, interactive interfaces.

Developed a mobile banking application using React Native. Collaborated with designers using Figma-to-code workflows (with high-fidelity mocks translated into accessible, pixel-perfect UI). Built reusable UI components with consistent design across the app. Implemented a transaction history experience with filtering, sorting, and search to help users track spending by date, category, and amount. Designed secure authentication flows aligned with mobile security best practices. Optimized mobile performance through lazy loading, memoization, and image caching, cutting load times significantly on older devices. Also built a full CRUD lost & found platform experience with JWT authentication, enabling users to report and retrieve items for faster recovery workflows.
