## About

```text
At Coditation, I designed the system architecture for Vintavia’s AI itinerary planner, reducing response latency from 40 seconds to 2. I also optimized its agents’ LLM usage, cutting monthly AI costs by 72%.

I architected a multi-agent scraping and validation pipeline for place data, reducing manual curation by 90%. I built semantic search for natural-language itinerary queries and developed a FastAPI backend integrating Google APIs and TfL API.

At Truefunds, I integrated mutual fund APIs into a unified data layer for real-time portfolio tracking and live NAV updates. I also built a self-healing financial news scraper with automated schema change detection.
