About

I’m a Data Engineer / Analytics Engineer with nearly 3 years of experience working across data engineering, analytics, and data quality, with a focus on building reliable pipelines and reporting-ready data. In my current role, I work with SQL, dbt, Python, data modeling, data-quality validation, and scheduled data workflows across retail and e-commerce datasets. Some of the work and outcomes I’ve delivered include: → Worked with datasets containing 300M+ records across 5–6 data pipelines and 2–3 data sources. → Enhanced 7–8 dbt models covering transformation logic, business rules, and Fact & Dimension modeling. → Reduced manual data-quality testing effort by 40% through reusable dbt validation covering 7+ quality dimensions. → Improved pipeline reliability by 60–70% by resolving recurring production issues across data types, primary keys, missing records, duplicate loads, and incremental processing. → Reduced data-processing time from 1+ hour to approximately 10 minutes through SQL/dbt workflow improvements. → Achieved 90%+ source-to-target data matching while validating incremental jobs for consistency and idempotent processing. → Supported reporting and data-quality analysis for 20+ stakeholders using Python, Tableau, and Streamlit. My current technical focus includes: Python | SQL | dbt | Apache Airflow | Snowflake | PostgreSQL | AWS S3 | GCP | ETL/ELT | Data Pipelines | CDC | Incremental Loading | Data Modeling | Data Warehousing | Data Quality | Docker | Git I’m currently looking for opportunities as a: Data Engineer | Junior Data Engineer | Analytics Engineer | ETL Developer I’m an Immediate Joiner and open to opportunities across India.
