NISHU TOMAR

I’m a results-driven Senior Business Analyst with 4.8+ years of experience translating complex business problems into data-driven solutions across EdTech and AI-powered CX platforms. I’m known for advanced SQL, Power BI, Python, and BigQuery—delivering executive-ready insights, automating reporting pipelines, and driving measurable business impact.

In my recent role at Rezo.ai (AI-Powered CX & Contact Center Automation), I led end-to-end analytics delivery for enterprise clients by owning KPI definition, SQL pipeline design, Power BI dashboard development, and executive reporting. I also designed real-time dashboards for call bot performance, SLA adherence, and CSAT, and automated recurring reporting workflows to reduce reporting turnaround by ~60% across 100+ dealer touchpoints.

At PhysicsWallah Ltd (PW), I led analytics across Sales, Academic, and Operations, supporting decisions for 50,000+ active students and 100+ centers. I engineered scalable SQL pipelines on PostgreSQL and BigQuery processing 1.6M+ student records, reduced query execution time by 40%, and automated 12+ recurring reporting workflows using Python and Apache Airflow—saving 15+ hours of manual effort per week.

Across both domains, I focus on stakeholder management, KPI definition, and cross-functional collaboration with Product, Engineering, QA, and leadership. I use advanced analytics like funnel/drop-off analysis and A/B testing, and apply data engineering practices (ETL pipelines, orchestration, and reporting automation) to make insights timely, reliable, and actionable.
