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.
