React UI for Robot Control: Delivered a real-time cobot control interface with 3D rendering, leveraging WebSockets, Three.js. Optimized bundle size by 25%, removed dynamic injection to ensure full offline functionality. React Performance Optimization on 4-Core CPU: Achieved sub-100 ms INP by offloading the LCP 3D model load to a Web Worker rendering an immediately interactive 3D UI, and reduced per-core CPU usage from 100% to 15% on an UpSquared-hosted React app by conditionally throttling and batching communications to 200 ms preserving smooth and real time animations, validated via Lighthouse User Flow, Performance Panel, and htop. Multiplexing Architecture with Angular and Node.js: Engineered a channel-based messaging system over a single WebSocket connection using RxJSs multiplex pattern in Angular and a subscription management layer in Node.js, enabling pub/sublike communication and reducing connection overhead by 45%, cutting bandwidth usage by 30%. Desktop Application w React + Electron.js: Developed a Windows 11 Pro desktop and tablet application using React + Electron for humanoid control, point cloud visualization, camera feed streaming at 30fps 720p via WebRTC. Authentication and Access Control: Designed and implemented authentication and role-based access control (RBAC) in React and Node.js, securing 100% of 10+ route navigations on the frontend and enforcing backend API authorization using JWT-based authentication and role permissions. API Development in C++: Enhanced the C++ API to efficiently handle bidirectional communication between the web app and the robot. Implemented Csv based storage reducing retrieval time by 1 second.

Satellite Data Integration: Integrated Orbify in Angular app to showcase EUDR compliance data for farms, leading to the acquisition of new domestic and international clients and a 40% boost in revenue. Google Maps polygon creation: Embedded Google Maps and developed polygon creation and editing features, enabling users to plot farms and restricted zones, allowing 2% overlap, and visualize Geo Spatial data effectively. Admin Settings Module: Architected Admin Settings Module to configure languages, time zones, currencies, etc., for real time updation of user-specific preferences allowing customization of product and providing 100% user satisfaction. NgPackagr Library Development: Created a tree-shakable, lightweight Angular + TailwindCSS component library to accelerate feature delivery, reducing peer review time by 20% and enhancing code consistency. Decreased bundle bloat by 100kb by removing third party libraries and building required components from scratch with TailwindCSS.

Automation Testing: Authored automation test scripts for IBM Sterling OMS to ensure a seamless transition of data from Oracle PRP, identifying 12 critical vulnerabilities. Integrated Allure reports for detailed reporting.
