Vishnu Pratap Singh Rathore — AI & Backend Engineer

About

About Me

I'm a backend and AI engineer with 3+ years of experience building systems that go beyond simple API wrappers — from multi-modal AI pipelines and ReAct agent frameworks to production FastAPI services handling real users.

My background sits at an unusual intersection: I've built robotic arms, deployed LLMs on edge hardware, integrated MCP servers for agentic tool use, and shipped RAG systems used by real businesses. I care about making AI that actually works in production — not just in demos.

I work best in small, high-ownership teams where the goal is clear and the implementation is mine to figure out. When I'm not building, I'm usually reading about the next thing I want to build.

Things I've Built

Agent Pie

GitHub

AI training coach for kitchen staff

LangChain LangGraph FastAPI PostgreSQL RAG Streamlit

An AI-powered training system for chefs and cooks in hotels, restaurants, and cafes. Upload recipes and kitchen guidelines; Agent Pie converts them into step-by-step instructions, generates practice quizzes, and opens a chat interface where staff can ask questions specific to any step, ingredient, or cooking technique.

Controlled API costs via semantic search that passes only the most relevant context per call. Embeddings processed asynchronously server-side with contextual loading feedback.

RAG-Powered Website Q&A

Ask anything about any website

LangChain FAISS Groq LLaMA 3.2 Streamlit

Full RAG pipeline that ingests website content, indexes it semantically, and answers user questions with source citations and confidence-aware responses.

Dual 6+6 DOF Robotic Arms

Two arms, one coordinated task

ROS2 Python Embedded Hardware Sensors

A pair of robotic arms with 6 DOF each, coordinated to perform a precise physical manipulation task. Led a team of 3 interns. First failure was the power supply, which was solved by redistributing to separate sources for motors and electronics.
