## Headline

Data Analyst \| SQL • Python • Power BI \| ETL & Data Pipeline Development \| Turning Raw Data into Business Insights \| IIT Guwahati Certified in Data Science & AI

## About

I help businesses turn raw, messy data into clear, actionable insights\. With hands\-on experience across financial and mobility datasets, I specialize in building end\-to\-end data pipelines — from raw ingestion and cleaning to interactive dashboards that drive decision\-making\. What I bring to the table: \- Advanced SQL \(CTEs, Window Functions, Joins, Subqueries\) for high\-volume, complex datasets \- Python \(Pandas, NumPy\) for automated ETL pipelines that cut manual reporting effort \- Power BI \(DAX, Star Schema\) — designed 15\+ interactive dashboards tracking supply\-demand and operational KPIs \- Rigorous data QA — building sanitization protocols that reduce downstream errors in reporting and predictive modeling \. Recent impact: \- Optimized SQL queries to bring multi\-gigabyte dataset processing down to seconds \- Built Customer360, Order360, and Product360 models to uncover revenue drivers and customer segmentation patterns \- Engineered dashboards analyzing 20\-year market trends and ride\-hailing "stress hours vs\. golden hours"\. Currently deepening my expertise with an Advanced Certificate in Data Science & AI from IIT Guwahati\. Always open to conversations about data, analytics, and how to make numbers tell better stories\. Let's connect\! 📧 rishavsinghrajput9934@gmail\.com 💻 github\.com/Rishav656

## Work experience

Data Analyst at Billions United, May 2026 \- Present · 5 mos, Bengaluru, Role Overview: As a Data Analyst Intern at Billion United, I served as a core member of the analytics team, taking end\-to\-end ownership of the data lifecycle\. My mandate was to transform raw, fragmented data into high\-fidelity assets that drive executive decision\-making\. I bridged the gap between complex technical infrastructure and strategic business needs by implementing rigorous data engineering standards and advanced analytical practices\. Core Technical Competencies & Contributions: End\-to\-End Data Lifecycle Management: Spearheaded the full data lifecycle, from initial raw ingestion to final transformation\. I established robust pipelines to intake unstructured data, applying meticulous cleaning and normalization techniques to curate high\-fidelity datasets\. This provided the foundation for reliable, executive\-level business intelligence\. Advanced SQL & Relational Database Engineering: Architected and executed multi\-layered SQL queries to synthesize data from disparate sources\. I leveraged advanced SQL functionality, including complex Joins, Window Functions, Aggregate Functions, and CTEs, to perform intricate data manipulation\. My focus remained on query performance, writing index\-aware scripts that maintained low latency even when processing massive, multi\-gigabyte historical datasets\. Rigorous Quality Assurance \(QA\) & Data Sanitization: Instituted a multi\-stage data sanitization protocol to eliminate "data noise\." By systematically identifying and rectifying missing records, resolving structural inconsistencies, and managing outliers, I ensured that all analytical outputs met the highest standards of integrity\. This proactive QA framework significantly reduced downstream errors in predictive modeling and reporting dashboards\. Strategic Data Mining & Performance Analysis: Applied sophisticated data mining methodologies to uncover latent operational patterns and systemic bottlenecks\.

Data Analyst at AnalytixLabs, Aug 2025 \- Apr 2026 · 9 mos, Bengaluru, •Designed relational database structure integrating company metadata and 25\-year historical trading data for financial analysis\. •Market Volatility Analytics: Developed complex SQL scripts to identify high\-volatility trading periods by calculating daily price spreads \(High vs\. Low\) and relative price categories \(High/​Medium/​Low\) using Subqueries and Aggregations\. •Trend & Performance Attribution: Engineered a Power BI dashboard to visualize the "Quarterly Performance Cycle," enabling stakeholders to identify 20\-year trends in stock closing prices and year\-over\-year growth metrics\. •Advanced Query Optimization: Optimized data retrieval by implementing CTEs to find "Above\-Average Trading Days," reducing query runtime for large\-scale historical datasets and improving report latency\. •Strategic KPI Reporting: Created automated logic to track Monthly Market Highs and Price Sensitivity, providing actionable insights into historical resistance levels and trading volume peaks\.
