Hi! I'm Ericka

Cat Parent & Full-stack AI Developer

I like solving problems with people. Made of books and Monster Energy.

About me

Hello there! I'm Ericka, a problem solver who often ends up writing code to fix things. I believe in the power of teamwork and thrive in finding how all the pieces fit together. I care about good system design, clean code and responsible AI. When I'm not coding, you'll find me enjoying a book next to my cats.

How I roll

Tech is always about people.

I focus on products that make people happy and building structure that actually helps engineers grow.

Leadership

I stay close to the work — the team, the code, the decisions. Good systems come from teams who trust each other; that's what I love most.

Responsible Technology

Technology should leave people better off than it found them: that's not a given, it's something you must build for on purpose. I spend real time on the intersection of AI and ethics.

Teaching

Teaching tech for a few years now; honestly, maybe the biggest impact I get to have, and I just love doing it. Grateful to add my grain of sand to future colleagues. Taught programming, databases, cloud, even Spanish.

Always Learning

I'm a book nerd first and foremost. But what really pulls me in isn't the next framework or tech stack, it's research, the impact tech has on society, and hearing what brilliant minds are figuring out right now.

System Design

I love a system that just makes sense, but it alone doesn't solve the problem: it only works when the whole team and the client are actually on the same page. So I spend as much energy listening and translating as I do designing.

“Not finance. Not strategy. Not technology. It is teamwork that remains the ultimate competitive advantage.”

Peer-reviewed

I believe ML shouldn't cost people their privacy. That belief is basically what my published research is about: federated learning and privacy-preserving ML.
