Hi, I'm Yessie.
I build software for finance companies. I teach small-business owners to set up AI the way an engineer would: once, carefully, and with nothing sent until they've seen it.
I'm a lead software engineer in FinTech. I've led engineering teams, helped shape product roadmaps, and spent 8+ years building systems people rely on every day. I teach in English and in Spanish.

Learn AI, Build Your Business
Started teaching the careful way I work with AI, written down step by step, in English and Spanish.
I took the long way into engineering. A decade in hospitality taught me how to explain things to people who don't share my technical context, and how to stay level when something breaks and it matters.
What my managers wrote
“When the stakes are high and the changes are risky, she steps in like a deployment ninja — calm, confident, and always in control.”
“She exemplifies what a visionary contributor looks like. Someone who sees beyond their defined role, rises to meet challenges that others cannot, and elevates everyone around them in the process.”
The fun side
- Food
Tacos, any day. Mexican food is my jam.
- Sweets
Pastries are my weakness. Cookies, no. Chocolate, yes.
- Garden
I garden. My plants die. I keep gardening.
- House
Home improvement, the do-it-myself kind.
