From Raw Data to Real Insights: My Behind-the-Scenes H-1B Analysis Journey with SQL & Tableau ⚙️📊

Ever wondered how a messy Excel download becomes an interactive dashboard that brings H-1B trends to life? Here’s my workflow—warts, surprises, and wins included!

• Messy Beginnings: It always starts with untangling CSVs—missing values, typos, date mismatches. Enter SQL: the unsung hero of data wrangling.

• Transformation Magic: Complex queries let me join, group, and filter millions of records: approvals, denials, employer profiles, timelines. Suddenly, patterns emerge!

• Visual Storytelling: Once the tables make sense, Tableau helps convert rows into charts, maps, and interactive infographics that anyone can explore—giving wings to the data.

• Challenges (and Hacks): Whether it’s optimizing queries for speed or picking the right chart to make trends pop, every step is a lesson. I share tips and mistakes to help fellow analysts avoid common traps.

• Impact: Data storytelling is about finding the story behind the numbers—and making it memorable for employers, job-seekers, and policy thinkers.
