"Data is the new oil, but like oil, it must be refined to be valuable." β Peter Sondergaard
Hi there! I'm Avinash Rai, a results-oriented SQL Developer & Data Analyst with a passion for transforming raw data into actionable insights. From building robust ETL pipelines to designing impactful dashboards and automating workflows β I specialize in creating scalable, data-driven solutions that help organizations make smarter decisions.
πΌ I have hands-on experience working with tools like Snowflake, Power BI, Python, SQL Server, and Alteryx, delivering solutions across domains including finance, manufacturing, HR, and healthcare.
I'm a strong believer in automation, clean design, and reproducible analytics. I enjoy building modular pipelines, interactive dashboards, and efficient SQL logic that not only solve today's problems β but are future-proof and maintainable.
- π Designing automated ETL workflows (SQL, Snowflake, Alteryx)
- π Creating KPI dashboards in Power BI, Tableau, and Streamlit
- π§Ή Data cleaning, transformation, and modeling using Python (Pandas, NumPy)
- βοΈ Cloud-based data operations using AWS S3, GitHub, Streamlit Cloud
- β‘ SQL query optimization for scalable, real-time analytics
π Currently upskilling in DBT, Azure Data Factory, and Matillion for advanced data engineering workflows.
π§© Outside of data, I'm passionate about understanding systems β from backend infrastructure to business process design. Great analytics start with asking the right questions.
π« Feel free to connect or collaborate β Iβm open to freelance roles, projects, or just a good data chat!
