About Tiffany Teasley
I didn’t start my career in tech. I spent twenty years teaching high school math before moving into data science in my forties. My first data science interview ended in rejection. Instead of giving up, I figured out what I was missing, learned it, followed up with the same hiring manager, and eventually earned the job I was originally rejected from. That experience changed how I approach this field. Today, I work as a Data Scientist and AI Developer, building real AI systems and working on applied projects. I share what I’ve learned to help aspiring data scientists, students, and career changers move with clarity instead of guessing. I believe in- Building real projects - Explaining your value clearly - Learning with intention Credibility and recognition- LinkedIn Top Voice 2024 to 2025 - Named one of the Amazing People at LexisNexis - My transition story featured by Udemy and KDnuggets If you’re just getting started, begin with my free webinar: Breaking the Data Science Barrier Build proof. Explain it well. Move forward with confidence. — Data Sistah
