Integrated Redis caching into GraphQL API architecture to improve data fetching efficiency and reduce server load. Implemented query-level and resolver-level caching strategies to store frequently accessed data, ensuring faster response times and a smoother user experience. Utilized cache invalidation techniques to keep data consistent, especially for mutations and time-sensitive queries. Worked closely with backend and DevOps teams to ensure proper Redis configuration and seamless deployment across environments and worked as a DevOps engineer myself.

Developed a modern, responsive dApp for the Crypto Hunters using Next.js and SCSS, focusing on performance, SEO, and cross-device compatibility. Leveraged Next.js features such as static site generation (SSG) and image optimization to enhance load speed and search engine visibility.

Implemented animations, interactive sections, and reusable UI elements to improve user engagement and brand presentation. Collaborated closely with UI/UX designer and another frontend engineer to deliver a polished, user-friendly experience that aligns with the Cryto Hunters's branding and goals.
