Sep 2024 - Nov 2025 • 1 yr 2 mos

Company: IDCUBE Identification Systems. Worked on end-to-end data and ML systems for enterprise dashboards. Built a RAG-based chatbot (Aisha) that lets users ask questions in plain English and get answers pulled straight from company data — used across 9 dashboards. Designed an anomaly detection system that scores risk across 45+ parameters for a vulnerability tracking tool. Improved query performance on a dashboard handling 14M+ records, cutting response time in half through a better pagination approach. Also built REST APIs for a real-time data pipeline — pulling in raw data, cleaning and transforming it, and loading it into the target system.
