Senior Data Analyst and Power BI Developer delivering enterprise dashboards that drive decisions.
IndiaWhat I'm looking for
I’m a Data Analyst and Power BI Developer with 7+ years building enterprise analytics that drive decisions at the C-suite level. I’ve delivered 15+ production dashboards adopted by leadership across multiple organizations, with a focus on turning messy multi-source data into insight that sticks.
I specialize deeply in Power BI, DAX, SQL, Python, and dimensional data modelling. I’ve repeatedly improved reliability and performance—cutting report load times by ~35%, eliminating data quality issues, and diagnosing dataset refresh failures within 24 hours while establishing proactive monitoring that reduced recurring issues by ~30%.
I also bring strong governance and delivery discipline: I enforce Row-Level Security (RLS), workspace governance, and compliance requirements across dashboards. I enjoy translating ambiguous business requirements into delivery-ready BI specs for cross-functional stakeholders, mentoring junior BI developers, and shipping solutions that earn fast stakeholder adoption.
