Narasimha Royal | Data Analyst, Data Engineering & AI Analytics

About Me.

Data Analyst with 2 years of experience turning large, messy data into clear business decisions. Specialized in building Power BI dashboards on ERP data, automating manual reports, and finding where a process loses time. Skilled in SQL, Python, Power BI (DAX), PostgreSQL, SQL Server, BigQuery, and Airflow, with hands-on work across 44M+ records and a 2-to-3-hour manual report turned into an automatic morning refresh. Comfortable working with energy, supply chain, purchasing, and manufacturing data, and explaining results to non-technical managers.

Finding where a business is losing time and money, and fixing it, is the work I want. Based in Houston, open to Data Analyst, Data Engineer, Analytics Engineer, Business Intelligence Analyst, Supply Chain Data Analyst, and GIS Analyst roles.

- Python
- Built the data pipeline behind an internal knowledge base: ingests the organization's own content, cleans and chunks it, and loads it into a search index staff can query by topic.
- Moved the heavy work out of the request path and into the index, taking answers from tens of seconds to about one.
- Benchmarked 7 embedding models against a hybrid of keyword and vector search, and chose the setup that lifted retrieval accuracy by 15 points.
- Built an evaluation set so the system is measured on whether it answers what it should and declines what it should not, rather than on how good a single answer looks.
