During my tenure at Sportjacks as a Full Stack Developer, we specialized in building and optimizing web applications using Next.js, leveraging its advanced features such as Server-Side Rendering (SSR), Static Site Generation (SSG), on-demand revalidation, and two-factor authentication with NextAuth. Our key projects included developing and maintaining several platforms such as Sportjacks.com, Sportjacks Ecom, Sportjacks Supplier Portal, Sportjacks CRM, and Nandi Footwear.We designed and implemented scalable microservices using NestJS, integrated Kafka for asynchronous messaging, and utilized Docker for streamlined containerization. For real-time capabilities, we employed Socket.IO to deliver live updates and notifications. On the database side, we worked with both MongoDB and PostgreSQL, leveraging Drizzle ORM and Mongoose ORM for efficient data modeling and management.
