    As Head of Development at Wincity, I led the redesign of our API from Next.js to NestJS, optimizing our backend infrastructure for greater efficiency and scalability. I orchestrated the transition of our server from Vercel to AWS, enhancing the performance and reliability of our platform. My approach also aimed to improve developers' quality of life by introducing generic classes, facilitating better Web3 integration.

I integrated Alchemy as an RPC provider library, which increased our efficiency in blockchain development. I also established clear development workflows, accelerating the production cycle while maintaining high code quality.

    My leadership was instrumental in the development of our game, including graphical updates and bug fixing on the application, thus ensuring a seamless user experience. I successfully coordinated the development team, overseeing the development of smart contracts and the integration of an NFT marketplace/collection.
