Hi, I'm

Narapareddy
Senior Software Engineer & Tech Lead building AI-powered enterprise platforms at scale.
I love turning complex legacy systems into modern, intelligent platforms. Currently exploring how GenAI and LLMs can transform enterprise data workflows — and building the tools to make it happen.
01. About
I'm a Senior Software Engineer with 15+ years of experience building enterprise-scale systems across insurance, healthcare, financial services, and higher education.
Currently, I'm leading architecture and development of a large-scale data migration platform at a Fortune 500 insurance company — migrating 10M+ policies across 5,000 contracts from legacy mainframe to modern cloud infrastructure.
The most exciting part? I built an AI-powered chatbot using GPT-4 that enables teams to query complex data lineage in natural language — turning hours of manual investigation into instant insights.
