About

I co-founded an EV charging startup in 2021 with one goal, make electric vehicle infrastructure accessible across Bengaluru. No funding. No corporate safety net. Just a lot of hustle, and a real problem to solve. We deployed 2 commercial EV charging stations, got featured in Startup India Magazine, and learned more about building a business than any job could have taught me. We also made zero revenue. And I shut it down in 2025. That experience changed how I think about technology. I stopped seeing software as code and started seeing it as solutions to real, physical, frustrating problems. Now I am channeling everything I learned, the domain knowledge, the product thinking, the resilience into AI engineering. I am building with Python, LangChain, FastAPI, and the OpenAI API. My first project is an AI-powered EV route planner, the tool I genuinely wish existed when I was running FeedMyEv. My background: → 4 years co-founding and operating a hardware + software startup → Full stack development in React, Node.js, Express, MongoDB → Now building LLM applications, RAG systems, and AI-powered products → Based in Bengaluru, open to AI Engineer and Full Stack AI Developer roles If you are building something in AI, EV tech, or just need someone who can ship? let us talk. 📧 sunilkumarraos007@gmail.com
