Full Stack & AI Engineer
2.7 years of experience · Remote · India
I'm a full-stack engineer (2.7 years) who builds things that actually ship and scale. Over the past few years, I've worked across the stack—mostly living in Python, TypeScript, FastAPI, NestJS, Next.js, and AWS.
Now, my current focus is designing low-cost, low-maintenance software, with a strong focus on database design, architecture, performance, security, scalability, and cost.
I've also built a RAG system that analyzes my technical documents for personal use.
