Vinoth JK

I’m a data-driven developer with 6+ years of experience designing enterprise BI solutions across Finance, Healthcare, Sales, Supply Chain, and Insurance. I focus on turning complex data into actionable insights through strong modeling, performance tuning, and clear KPI storytelling.

I’ve developed 15+ interactive Power BI dashboards supporting 200+ stakeholders, improving decision-making efficiency by 30% and saving 8 hours per week. I’ve built star-schema models for millions of records and optimized report load times by up to 45%, while developing reusable DAX measures for business KPI tracking (including Forecast Accuracy, Fill Rate, and YoY Growth).

On the data engineering side, I automate ETL and reporting workflows using Power Query, SSIS, Python, Azure Data Factory, and Azure Databricks. I’ve reduced manual work by 12 hours per week, lowered reporting errors by 40%, and improved data quality through cleansing, validation, and governance techniques like Row-Level Security (RLS) and incremental refresh.

I also integrate Generative AI to accelerate BI development and troubleshooting—using Claude AI, ChatGPT, and Microsoft Copilot to speed up SQL/DAX generation, optimize logic, and improve delivery timelines. Whether migrating from Tableau to Power BI or mentoring junior developers, I aim to deliver reliable, secure, and fast reporting that teams can trust.
