Hi, I'm Ayush, a full stack developer who builds web apps, mobile apps and AI powered features that feel smooth and actually work in production.
I build with React, Next.js, Node.js, TypeScript, FastAPI, and Spring Boot, mobile apps in Flutter, Kotlin, and Swift, and AI features with OpenAI, Claude, and Gemini. I also fix bugs in existing projects and write technical blog posts on JavaScript and Node.js on Hashnode.
