Senior Full Stack Engineer | Frontend Heavy | React.js • Next.js • Node.js • TypeScript | BFF • AI Engineering • Scalable Architecture

About

I'm a Frontend-Heavy Full Stack Engineer with 7+ years of experience building scalable web and mobile applications using React.js, Next.js, TypeScript, Node.js, and Express.js. My core strength is frontend architecture — component systems, performance optimization, state management, and modern rendering patterns — and over the last two years I've expanded that into full-stack ownership across BFF/API design, REST APIs, authentication, and backend workflows using Node.js, Express.js, and MongoDB. I like owning features end-to-end: from UI and API/BFF integration through testing, deployment, and production support, working closely with backend, QA, DevOps, and product teams to ship reliably. A few things I'm proud of: 🔹 Improved Core Web Vitals at Gupshup — raised Lighthouse performance by 20%, cut LCP by 200ms, eliminated CLS issues 🔹 Resolved critical production issues across 200+ claims at Acko, working across frontend, BFF, and backend layers 🔹 Delivered a 25% lift in customer engagement through Ad Authoring features 🔹 Mentored and led frontend engineers across multiple teams 🔹 Built and scaled a Click-to-WhatsApp campaign platform across Facebook, TikTok, and Google Ads I also use AI-assisted development tools (GitHub Copilot, Cursor AI, ChatGPT, Claude) to move faster on debugging, testing, and refactoring — without losing rigor on code quality. Currently focused on: React.js, Next.js, TypeScript, Node.js, Express.js, MongoDB, BFF architecture, and building products that are fast, reliable, and genuinely well-engineered. Open to Senior/Staff Frontend and Full Stack Engineer roles at product companies.
