What's in this course? ⚡️
Chapter 1: Intro & The Basics
- The exact 4-keyword query that pulls any data you want from any table (you'll write your first one in the first 15 minutes)
- Why "primary keys" are the secret to never accidentally double-counting your data in interviews
- The one data type mistake that breaks 90% of beginner queries — and how to spot it before it costs you
- How to clean messy text data (extra spaces, weird capitalization, mixed formats) in a single line of SQL
Chapter 2: Filtering Datasets & Wildcards
- How to find specific rows in a dataset of millions — without scrolling, sorting, or guessing
- The 6 logical operators that let you ask SQL almost any business question you can think of
- Why most beginners get NULL values wrong (and the simple rule that fixes it forever)
- The wildcard trick that lets you search for patterns when you only remember part of the name
Chapter 3: Functions, Dates, & Grouping
- The "GROUP BY" move that turns a 10,000-row table into a 1-slide answer your boss actually wants
- 3 date functions that handle 95% of every "last 30 days / this quarter / year-over-year" question
- The difference between COUNT(*) and COUNT(column) — and why getting this wrong on an interview question is an instant red flag
- How to answer questions like "what's our average customer spend by month?" in a single query
Chapter 4: Bridging the Gap to Intermediate SQL
- Your first JOIN — the single most important SQL skill in every data interview, broken down so it finally clicks
- How to combine data from multiple tables (the way every real-world dataset is actually structured)
- The CASE statement: how to create custom categories and bucket your data on the fly
- The "fact vs. dimension" framework that helps you make sense of any database you've never seen before
Chapter 5: Case Studies & Final Portfolio Project
- Walk through real analyst case studies — including how to calculate percentages in SQL (one of the most-asked interview questions)
- How to visualize SQL results so they actually tell a story instead of looking like a wall of numbers
- Where to find free, real-world datasets to keep sharpening your skills after the course
Build Your First Portfolio Project 🎉
- The complete walkthrough of your first SQL portfolio project — the one you'll link on your resume and show in interviews

Hi, I'm Jess 💅
I used to be a corporate analyst making $73K, watching coworkers with the "right" backgrounds get the promotions and the offers I wanted 😥
Today, I'm a former Senior Data Analyst in tech, the founder of Big Data Energy ⚡, and I've built an audience of 600,000+ followers across platforms while helping 500+ paying students land high-paying data jobs.
Here's the short version of how I got here:
I have a math degree (still kind of shocked by that, tbh!! 🤯) and a Master's in Business Analytics. I spent years learning the hard way — expensive graduate programs, trial and error in real corporate roles at companies like Crunchbase and other fintech startups, and more than a few moments of feeling completely lost.
I've also been underpaid, overlooked for promotions I earned, and strung along by companies that didn't value what I brought to the table (their loss, LOL).
But I eventually went from $73K to $153K in just 11 months 💰 by learning what actually mattered, advocating for myself (hello negotiation!), and refusing to settle.
Now I teach SQL and data analytics to a community of 600,000+ — and through my courses, I've helped students land their dream data jobs with $25K–$31K salary increases, often in just a few months.
Here's what genuinely bothers me about this industry, and why I built this course 👇
You've probably seen the data influencers posting things like "I broke into a $100K data role with NO degree and NO experience in just 3 months!"
Meanwhile, if you dig a little deeper, you'll find they have an MBA, a STEM undergrad, or years of adjacent work experience they conveniently left out of the headline 👀
That kind of content? Actively harmful 🚨 It sets real beginners up to feel like they're failing when they're actually just following bad advice.
I got my Master's so you don't have to. This course is me handing you everything I learned — the actual fundamentals, without the expensive tuition, the wasted years, or the misleading hype.
Breaking into data isn't easy. But it's absolutely achievable — and I'm going to show you exactly what to focus on so you're not wasting a single second on the wrong things 🥳
