At EXL, I build transaction-level fraud detection and merchant risk-scoring systems for a global payments client, achieving 82% precision and strengthening identity verification through OCR, document validation, and image feature extraction. Previously, I deployed a multi-agent procurement chatbot on AWS at Zycus, built OCR-driven invoice and identity-validation workflows, and developed LLM-based policy simplification. Across Fantasy Akhada, Tiger Analytics, and CoreCompete, I've improved ARPU by 11%, increased retention by 17%, improved forecasting accuracy by 5–10%, and reduced server downtime by 85% through machine learning, analytics, and production automation.
