# Projects

## Autonomous Multi-Agent Web UI Automation System

- **Overview**: Developed a multi-agent system using **LangGraph** and **Playwright** to navigate non-deterministic UI changes across 5 high-complexity SaaS platforms.
- **Impact**: Increased task completion success rate from **68% to 94%** by implementing a two-stage verification loop with step-level assertions and exponential backoff for dynamic DOM states.
- **Observability**: Integrated **LangSmith** traces for observability, reducing the mean-time-to-debug for broken selectors by **14 minutes per incident**.

## Proxy TuNER: Advancing Cross-Domain Named Entity Recognition through Proxy Tuning

- **Overview**: Improved cross-domain NER F1-score by **8%** by implementing a proxy-tuning approach for **LLaMA 2 models** (7B, 7B-Chat, 13B) using logit ensembling and gradient reversal.
- **Optimization**: Optimized inference performance by **30%** and reduced training costs by **70%** through distributed execution and model path optimizations in **PyTorch**.

## IntelliMeet: AI-Enabled Decentralized Video Conferencing App

- **Overview**: Architected a secure, decentralized video platform using **WebRTC** and **federated learning** to maintain data privacy while sharing only aggregated model updates.
- **Reliability**: Reduced call dropouts by **25%** by engineering network recovery logic and on-device **RetinaFace** attention detection for client-side quality adaptation.
