What I'm looking for

I’m looking for a Data Analyst role where I can build KPI dashboards and scalable data models with Power BI, SQL, and Python, work with large datasets, and collaborate with stakeholders to deliver actionable, measurable business insights.

I’m a Data Analyst with hands-on experience in Power BI, SQL, and Python, specializing in building scalable data models and KPI-driven dashboards. I enjoy turning large, messy datasets (100K+ records) into clear, decision-ready insights that improve business performance.

In my Data Analyst Intern role, I processed and transformed 100K+ records by converting epoch timestamps into structured date formats and building a dynamic calendar table. I designed a star-schema Power BI data model integrating multiple datasets, enhanced interactive dashboards for project performance and funding trends, and standardized financial metrics using USD conversion. I also wrote SQL queries for data extraction, transformation, and validation to ensure reporting accuracy and reliability.

Earlier, as an AI/ML and Big Data Trainee, I planned and optimized SQL-based data pipelines processing 50K+ records to improve query efficiency and enable faster analysis. Alongside that, I’ve built dashboards for company finance analysis and developed ML-driven projects like an accessible document reader and image-based sign language prediction—practicing data cleaning, modeling, and experimentation with measurable accuracy gains.
