Full‑stack developer specializing in React/React Native, Node.js, BLE integrations and blockchain solutions.
IndiaWhat I'm looking for
I am a full‑stack developer with hands‑on experience building React, React Native and Node.js applications for EV management and blockchain projects. I focus on delivering performant, production‑grade features with attention to UX and maintainability.
At Autoven I led frontend work, designed UI/UX, engineered real‑time BLE navigation, and replaced inefficient charting with a custom React Native WebView module, improving visualization performance by 70%.
I built RESTful APIs with robust filtering, pagination and bulk operations, implemented Firebase Cloud Messaging and adopted TDD to reduce debugging time by 30%. I also developed high‑frequency BLE streaming apps and server‑side pagination for large datasets, improving load performance by 40%.
Previously, I prototyped an NFT marketplace using React, Node and Ethers.js, wrote Chai unit tests for ERC1155 contracts, and implemented minting/trading flows that reduced QA workload and page load times. I hold a B.Tech in Computer Science and blockchain certification from IIT Kanpur.
