About

More than five years building software that people use every day.

I am a Full Stack AI Engineer. I design enterprise applications, generative AI platforms, and microservice architectures, then deploy them on AWS and Google Cloud. The work spans agriculture, education, insurance, marketing, and communication.

Recent work includes FarmEase for 50,000+ farmers, chatbot campaigns for 30,000+ people, evaluation of 50,000+ answer sheets, and an insurance audit flow that cut manual effort by 90%. I also teach a DSA course and a generative AI course on this site.

Core strengths

  • Generative AI — retrieval, chatbots, and document pipelines with LangChain, RAG, vector databases, NLP, and speech.
  • Full-stack systems — Angular, React, Node.js, and Python, from the API through cloud deployment.
  • Shipped products — farm guidance, student support, campaign messaging, and insurance audits used by tens of thousands of people.

Core expertise

End-to-end ownership from APIs and data to deployment, security, and intelligent automation.

Full-stack development

Angular, React, Redux, and Material UI on the front. Node.js, Express, FastAPI, and Flask services behind REST APIs.

Backend & system design

Microservice and event-driven systems, API design, Docker, Nginx, PM2, and CI/CD with GitHub Actions.

Cloud & DevOps

AWS and Google Cloud, containerized deploys with Docker, and production hosting behind Nginx. Databases include MongoDB, PostgreSQL, MySQL, Firebase, and vector stores.

AI & machine learning

LangChain, RAG, prompt engineering, AI agents, embeddings, document intelligence, NLP, ASR, and model APIs from Mistral, Gemini, and OpenAI. Fine-tuning where the product needs it.

Document intelligence

Knowledge retrieval over vector databases, OCR for answer sheets, document classification, and analytics used by farmers, students, and campaign teams.

Courses & integrations

Secure APIs and authentication, WhatsApp campaign workflows, and multilingual translation. The DSA course and the generative AI course on this site are built from the same practice.

Experience

Public-sector platforms at NIC Raipur, and earlier product work at Irin AI and GoSpring AI.

Courses

Two courses and a Python editor that runs in the browser. The editor draws each step: boxes for lists, circles for trees and graphs, and a fork for if and else.

DSA · Python

The Ultimate DSA Master Course

Arrays, linked lists, stacks, queues, trees, graphs, recursion, dynamic programming, searching, sorting, and interview problems. The roadmap shows what to learn first. Open a lesson and watch the structure change as the code runs.

AI · ML

Foundations of Artificial Intelligence

Search, logic, machine learning, deep learning, language, vision, and reinforcement learning, plus prompt engineering and RAG. The snippets open in the same Python editor.

Python editor

Write Python and press Run. Step through the lines. Lists are boxes, stacks and queues are piles, trees and graphs are linked circles, and a recursive call stays large beside a small map of the other calls.
