- Architected and delivered scalable, high-performance web applications using Next.js with SSR, ISR, and dynamic routing, resulting in a 30% improvement in page load speed and a 20% boost in user engagement. I led the integration of real-time data pipelines via WebSocket and MQTT for live BLE device monitoring with near-zero latency. - Developed AI-powered fault detection using TensorFlow.js and custom APIs, reducing device downtime by 15%. I also established CI/CD pipelines with GitHub Actions and Azure Pipelines, cutting deployment time by 40% and supporting zero-downtime releases on Vercel and Azure. - Additionally, mentored a team of 5+ developers, enforced code quality through PR reviews, and promoted best practices with ESLint, Prettier, Jest, and Playwright. I collaborated closely with product owners and designers in Agile environments to deliver impactful, user-centric features.

- Developed key components of Amazon’s e-commerce UI using React.js and Redux, implementing advanced state management with Redux Thunk and Saga, resulting in a 25% improvement in page responsiveness. Designed and built secure Node.js microservices with Stripe integration and JWT-based RBAC authentication to ensure scalability and compliance. - Optimized PostgreSQL performance by refining queries and indexing strategies, increasing transaction speed by 20%. Took ownership of end-to-end feature delivery with thorough unit, integration, and E2E testing using Jest, Enzyme, and Postman, reducing post-release defects. - Automated CI/CD pipelines with AWS CodePipeline, ECS, and ECR, enabling rapid and reliable deployments in a high-velocity environment.
