Experience

Data Analytics Specialist III

Uber (Intern → Full-time), Hyderabad

January 2026 – August 2026

Managed 40+ automated data workflows, reducing manual analyst effort by 20+ hours weekly across APAC operations.
Resolved ETL pipeline and BI synchronization failures, restoring 99%+ data reliability for daily stakeholder reporting.
Built an end-to-end anomaly-detection tool covering FIFA World Cup 2026 operations across 16 venues, surfacing demand spikes up to 12x within a 24-hour SLA. The work supported mitigation of an estimated $40M–$75M financial-leakage exposure, with analysis suggesting 30–60% was recoverable through immediate action.
Built a recurring operations dashboard for incomplete grocery orders in Sri Lanka, raising CSAT from 3.7 to 4.5/5 and cutting 1-star ratings from 23% to under 1% through proactive outreach.
Automated defect-rate anomaly detection with LLM-driven summarization, enabling early-warning root-cause analysis ahead of business reviews.
Designed an end-to-end campaign funnel tracker for 2,100+ stalled driver applicants in ANZ, surfacing data-backed fixes for supply bottlenecks.
