Systems-oriented full-stack engineer building production applications using MERN, TypeScript, Bun, and Fastify.
I design backend architectures with structured APIs, authentication flows, RBAC, database modeling, and Dockerized deployment pipelines. On the frontend, I build type-safe React applications with scalable state management and clean component architecture.
I have experience integrating LLM APIs (Gemini) into backend systems to power dynamic learning and content-generation workflows.
