## What I'm looking for

```text
I'm looking to build reliable, production-ready AI and backend systems where I can apply RAG, agentic workflows, Java, and Spring Boot to solve meaningful automation and product problems.
```

## About

```text
I'm currently building production RAG and agentic AI systems at Ajarow IT Services, including an item-replacement recommendation engine for a US e-commerce client and an autonomous document-generation agent.

I use LangChain, FAISS, GPT-4o, Python, Streamlit, and FastAPI to turn product specifications and natural-language requests into useful outputs. I build reliability in from day one through retry logic, exponential backoff, fallbacks, centralized error handling, and REST APIs.

Previously at Wipro, I developed Java and Spring Boot backend modules for logistics tracking, shipment lifecycle management, and microservice integrations. I worked with MySQL, PostgreSQL, Spring Data JPA, and JUnit, contributing to a project-management improvement that increased delivery efficiency by approximately 35%.
