NPLUS BOX is a lightweight NFT wallet that helps users manage digital assets across multiple blockchains.

In the NPLUS BOX project, I served as the technical leader and project manager. As the technical lead, I evaluated and selected front-end frameworks to build the product UI. For the back-end, I designed the system architecture on AWS and led development of microservices using Docker and Kafka to achieve high scalability. I also enforced code review policies and QA processes to guarantee product quality.

During development, I spearheaded solutions for three major technical challenges:

I introduced modularized front-end architecture using Webpack and React, which accelerated feature development by 40% and reduced code coupling.

I designed an indexed caching approach for NFT metadata querying, reducing the average request latency from 300ms to under 100ms.

I leveraged React Native to quickly package the product for both iOS and Android.

NPLUS BOX supports major blockchain ecosystems including Ethereum, BSC and Polygon. It also integrates WeChat Pay and Alipay to facilitate NFT purchases for Chinese users. Additionally, the wallet aggregates users' NFT collections across multiple wallets for a consolidated view.
