Hello, I'mGaurav.
I'm an AI Full-Stack Engineer with 2+ years of experience building production software from scratch — bridging cutting-edge LLMs and autonomous agents with robust, scalable full-stack architectures. At Certa AI, I architected custom RAG retrieval platforms and built full-stack internal management systems using Next.js, TypeScript, and FastAPI. At Persist Ventures, I architected high-throughput distributed email infrastructure, built Persist Wizard, and engineered AI-driven platforms like PumpGym and Tatbox AI.
