Chaitanya Sharmaai & full-stack dev
available for new builds

Hi, I'm Chaitanya Sharma —

I build AI products, SaaS and automations that run your business.

AI & Full-Stack Developer and Anthropic Claude Certified Developer. I build production SaaS, AI agents, internal platforms and n8n / GoHighLevel automations with Python, React, FastAPI and modern AI APIs — and I'm the founder of Charyx Labs. I design, build, integrate and deploy the whole system, not just one piece of it.
