About Rupashri J

I’m a Senior Frontend Engineer with experience building large-scale, performance-critical web applications using Angular (19+), React, TypeScript, and JavaScript across MEAN and MERN stacks.I specialize in frontend architecture and state management, with hands-on expertise in Angular Signals, NgRx, and RxJS. I focus on designing systems that remain predictable, scalable, and easy to evolve as products and teams grow.My work centers on solving problems that matter at scale:Designing component and state architectures for complex UIsOptimizing rendering and change detection for performance-sensitive appsMaking clear trade-offs between Signals vs NgRx based on product needsBuilding clean integrations with Node.js, Express, and MongoDBI bring a product-first and data-driven mindset to frontend engineering. I care about user experience, reliability, and maintainability as much as shipping features. I’m comfortable owning frontend technical decisions, reviewing code, and raising engineering standards across teams. Skilled in leveraging AI-assisted development tools like Microsoft Copilot to accelerate delivery, enhance code quality, and drive innovation in enterprise-scale projects.What sets me apart is systems thinking — I don’t just implement requirements; I design frontend foundations that support experimentation, scale, and long-term velocity.I’m interested in Senior / Lead Frontend Engineer roles at product-focused, high-engineering-bar teams, where frontend quality and performance are treated as first-class concerns.

Experience

1. Specialist Programmer - L2

   Infosys

   Jan 2022 — Present · Bengaluru, IN

   Led development of enterprise-scale frontend modules using Angular (12–19), TypeScript, and JavaScript, supporting complex, high-usage applications.Designed scalable component architectures and state management patterns using Angular Signals and NgRx, with a strong focus on predictability and long-term maintainability.Applied React fundamentals (functional components, hooks, component composition) while working on frontend feature enhancements, POCs, and cross-framework evaluations, enabling smoother collaboration across Angular and React-based teams.Leveraged shared frontend principles across Angular and React — component-driven design, unidirectional data flow, and separation of concerns — to improve code consistency and reusability.Optimized performance using lazy loading, change detection tuning, memoization concepts, and RxJS best practices, improving UI responsiveness and load times.Integrated frontend applications with Node.js, Express, and MongoDB APIs, ensuring clean API contracts and efficient data handling.Actively contributed to code reviews, technical discussions, and design decisions, helping elevate frontend engineering quality across the team.Mentored junior developers on frontend best practices, state management, and performance optimization.
