About

Frontend Engineer with 2.8+ years of experience architecting high-performance web applications, AI-native interfaces, and design systems using React.js, Next.js, and TypeScript. Shipped products serving 2,000+ users, saved $14,000+ annually replacing commercial toolkits, and engineered real-time SSE/WebSocket streaming UIs. I specialize in building complex, interactive frontend surfaces that go far beyond static screens: 1. Rich-Text & Visual Editors: Selection-aware editing, custom canvas interfaces (TipTap/ProseMirror), patch preview UX, and multi-document state management. 2. Real-Time Streaming & Audio Workflows: Token-streaming chat pipelines (SSE), in-browser microphone recording (Web Audio API, AudioWorklet, WebSockets), and live waveform visualization. 3. Performance & Web Vitals: Route-level code splitting, list virtualization, and Playwright CI quality gates holding Total Blocking Time (TBT) under 200ms. 4. Component Architecture & Design Systems: Building reusable, accessible component libraries (Shadcn UI, Radix UI, Material UI, Tailwind CSS) driven by Swagger REST contracts. Core Technical Stack: - Languages & Core: React.js, Next.js (App Router), TypeScript, JavaScript, HTML5, CSS3, Tailwind CSS - State & Data: Zustand, Redux Toolkit, React Query, Context API, RESTful APIs, WebSockets, SSE - Testing & Tooling: Vitest, Playwright, Jest, React Testing Library, Cypress, Git, Monorepos, Docker - UI & Visualization: Shadcn UI, Radix UI, Material UI, Recharts, Mapbox/Leaflet Currently open to Senior Frontend Engineer, Frontend Developer, and Full-Stack Frontend roles (Remote / Hybrid / On-site in Bangalore).
