Building Real-World AI Applications as a Software Developer

I’m Atharva Naik, a Software Developer focused on building real-world applications powered by Generative AI and scalable backend systems. This post shares my journey, technical experience, and the tools I use to solve practical problems.

My Background

I am currently pursuing a Master of Computer Applications (MCA) at Savitribai Phule Pune University. During my academic journey, I developed a strong interest in backend engineering and AI-driven systems, which led me to work extensively with Python, FastAPI, and Large Language Models (LLMs).

Working with Generative AI

A major part of my work revolves around LLM-powered applications. I have built and shipped tools using technologies like:

• OpenAI APIs (GPT-4)
• Llama-2
• LangChain
• Retrieval-Augmented Generation (RAG)
• Vector databases such as ChromaDB

These systems helped improve developer productivity and reduced hallucinations in AI responses through better context retrieval.

from fastapi import FastAPI

app = FastAPI()

@app.get("/health")
def health_check():
    return {"status": "AI service running"}
