About

Data Analyst | Analytics Engineer skilled in SQL, Python, Power BI, Tableau, dbt Core, Databricks, and Apache Airflow. I build tested, documented pipelines (Medallion Architecture, dimensional modeling) and turn the output into business-ready dashboards and insights.

At Reason Analytics Softech, I automated manual SQL Server reporting across Sales, Inventory, and Logistics, cutting manual report prep and catching ~5% anomalous rows before executive dashboards.

Built 3 end-to-end projects: a customer analytics pipeline on 541K transactions (62.8% revenue from one segment, 1,841 at-risk customers, churn model ROC-AUC 0.781); an e-commerce platform on 99,441 orders linking a 7.87% SLA breach rate to a ~2-star drop in reviews; and a sales performance analysis in SQL Server and Power BI.

Machine Learning, Statistical Analysis, ETL/ELT, and Business Intelligence are central to how I work.

B.Tech CSE (AI & ML). Actively seeking Data Analyst, Analytics Engineer, or Data Engineer roles.

Experience

Data Analyst Intern at Reason Analytics Softech Pvt. Ltd. (2025-09 – 2026-01)

Refactored 5 SQL Server stored procedures and CTE-based queries into reusable pipelines, replacing manual report prep across Sales, Inventory, and Logistics.
Wrote T-SQL validation scripts using window functions to catch duplicate records and flag anomalous rows 5% of the dataset before they reached Power BI.
Merged 3 operational data sources into one Power BI dashboard using Power Query and DAX — Sales, Inventory, and Logistics KPIs in one place instead of 3 separate reports.

Technical Consultant Intern at Newscope Media (2024-11 – 2025-05)

Mapped client workflows to identify 4 operational bottlenecks, working with senior team members to evaluate issues and recommend process changes that reduced project turnaround from 7 days to 4 days.
Tracked 3 concurrent workstreams and turned client requirements into functional documentation used by a 5-person team for status reporting and coordination.
