Sarah Chen

Analytics Manager @ Microsoft

“Hieu completely transformed how our team consumes data. He rebuilt our entire Power BI environment from scratch with clean semantic models, lightning-fast DAX, and dashboards our execs actually understand. The time we used to spend wrangling reports is now spent on decisions.”

James Rodriguez

Head of BI @ Deloitte Vietnam

“Working with Hieu was a turning point for our analytics practice. His ability to translate complex business requirements into elegant data models is rare. He delivered a multi-source reporting suite in half the time we projected, and the quality was exceptional.”

Nguyen Thi Mai

CFO @ VinGroup

“Hieu built our financial reporting layer entirely in Power BI with DAX measures I didn't think were possible. Real-time variance analysis, rolling forecasts, and drill-through P&L now happen instantly instead of taking our finance team days. Exceptional work.”

David Park

Director of Data Strategy @ McKinsey

“Few analysts have Hieu's combination of technical depth and business intuition. He doesn't just build dashboards; he asks the right questions first. His data models are production-ready on day one, and he mentors junior team members with genuine patience and clarity.”
