Co-Founder at BIJB.study ● Career Coach ● Power BI Educator

I don’t just teach Power BI — I build analysts.

For 15+ years, I’ve been leading teams, fixing broken reporting systems, and helping businesses turn data chaos into clarity. I’ve trained over 1,000 professionals across the US, Japan, and Europe. My clients? Microsoft partners, banks, retail chains, and tech startups.

I co-founded BIJB.study to solve a simple problem: most trainings are boring, theoretical, and useless. I built a program that gets results — fast. It’s designed for real people with real jobs who want real skills.

Built reporting systems from scratch for $100M+ companies

Led corporate Power BI transformations in 3 countries

Created learning roadmaps for internal analyst teams

Helped career switchers go from “I’ve never opened Power BI” to “Here’s my dashboard for the C-suite”

I don’t care about buzzwords. I care about outcomes. If you want fluff, go to YouTube. If you want to become the analyst companies are fighting for, I’ll show you how.

CTO at BIJB USA ● Power BI Trainer ● Systems Architect

I don’t give lectures. I show what works — and how to build it.

With over 15 years in analytics and enterprise systems, I’ve delivered real-world solutions in banking, insurance, telecom, pharma, and logistics. I’ve coded. I’ve led. I’ve fixed broken systems and made dashboards that actually drive decisions. I’ve done this at JPMorgan, for fast-moving startups, and with business owners who needed clarity from chaos.

Led BI projects across the US and Europe

Helped companies increase profit while cutting waste

Teach Power BI from a business-first perspective: where to automate, where to optimize, where to win

This isn’t about theory. This is about execution.
If you want to get Power BI running — and delivering results in days, not months — I’ll get you there.
