Hey, I'm Dhivan ,a Data Analyst with 3+ years of hands-on experience at Wipro, where I worked with SQL every single day to solve real business problems across manufacturing and energy domains. I've built dashboards tracking $100M+ in global operations, improved forecast accuracy by 25%, and led data quality initiatives across 15+ regions. My work wasn't just academic it was production-level, high-stakes, and results-driven. I'm 3x Microsoft Certified and Google Cloud Certified, but more than credentials, what I bring is real industry context the kind you don't find in tutorials. I created my SQL notes because I remember how overwhelming it felt to learn SQL without any real-world anchor. So I built something different SQL taught like a story, where every concept connects, every query has a purpose, and nothing feels random. If you're a student, a career switcher, or someone prepping for data analyst interviews , I've been exactly where you are, and I built these notes for you. I don't just teach SQL. I help you think like an analyst.
