SAGAR SAHU

I’m a MERN stack developer who thrives on shipping resilient code that directly meets business objectives. I leverage React/Next.js to create engaging user interfaces, while architecting Node.js/Express backends for reliability and maintainability.

At Keychron India Pvt Ltd, I served as a Senior Frontend Developer, leading technical strategy for an e-commerce platform. I oversaw Shopify Liquid theme development and Online Store 2.0 migrations, built high-converting React landing pages and feedback systems for lead generation, and became a senior escalation point for front-end debugging and adoption of new technologies.

I also engineered practical internal tools—like a custom Stock Data Management tool and POS Dashboard—using Node.js/database integration to streamline inventory workflows. I improved critical site performance through front-end caching strategies and efficient dynamic data rendering for a faster shopping experience.

In earlier roles, I developed dashboards and real-time visibility: I built a React internal dashboard with CRUD operations and Metabase visualizations, integrated GPS/telematics data streams for validated live ingestion, and refactored reusable React components to enhance UI/UX and architecture. From the MERN portfolio side, I’ve delivered RESTful APIs with secure JWT authentication, MongoDB indexing for rapid search, payment gateway integrations, and deployed solutions with CI/CD on Vercel.
