What is DevWithData?
DevWithData is a free online platform to learn Power BI, SQL, and Python for data analytics. Unlike traditional video courses that end with a completion certificate, DevWithData measures what you can actually do with a performance-based Data Readiness Index (DRI) score.
The platform is built around Namaste Power BI — a structured, 59-episode video series that takes you from complete beginner to interview-ready data analyst. Every episode includes MCQ checkpoints that test your understanding, and your DRI score updates automatically as you progress through the course.
Who Is This Course For?
Beginners Starting in Data
If you're new to data analytics and want to learn Power BI from scratch, this course teaches you data import, Power Query, star schema modeling, and DAX — in the right order.
Professionals Switching Careers
If you're an Excel user or work in a non-analytics role and want to transition into data analytics, the structured curriculum gives you a clear path from basics to building a portfolio.

Why DevWithData Is Different
Most Power BI courses on YouTube and Udemy give you a completion certificate after you watch all the videos. But watching isn't learning. A certificate proves you sat through content — it doesn't prove you can build a star schema, write a CALCULATE measure, or explain context transition in an interview.
DevWithData replaces certificates with the Data Readiness Index — a score from 0 to 100 that reflects your actual MCQ accuracy, lesson completion rate, and learning consistency. It updates automatically as you learn, and recruiters can verify it on your public profile.
The course is also structured with a strict learning order. You can't skip to DAX without understanding data modeling first. You can't unlock Episode 5 without passing the Episode 4 quiz. This forced progression ensures you build skills in the right sequence — the same way a professional bootcamp would structure it, but completely free.
