    Hi, I'm a fullstack developer skilled in building scalable AI, web and mobile applications. On the front end, I specialize in React, Next.js, and prefer using Tailwind CSS for styling. I'm proficient with build tools like Vite, ESBuild, and SWC. For back-end development, I work with Express.js, GoLang, and Java, and am experienced with both relational (PostgreSQL, SQLite) and non-relational databases (Firebase Store, MongoDB). In mobile development, I am familiar with native Android and iOS, as well as cross-platform frameworks like React Native and Flutter, where I leverage native techniques to solve complex problems. I am also experienced in cross-platform development with C/C++ and adept at utilizing open-source libraries to meet project needs. I am well-versed in CI/CD workflows and tools such as CircleCI, and skilled in containerization and orchestration with Docker, Kubernetes, and serverless architectures. I have a strong foundation in computer science, and I am passionate about solving technical challenges with efficient, innovative solutions.
