Full Stack Engineer | Expert in React, Node.js, Python
Hi! I’m Preston Zen, a Senior Full Stack Developer and AI Engineer with over 10 years of experience building secure, high-performance applications from the ground up.
I specialize in modern JavaScript (React, Node.js, Vue), Python, TypeScript, and cloud platforms like AWS and GCP.
I’ve led development on projects ranging from crypto casinos and fintech dashboards to healthcare platforms and enterprise SaaS tools.
Throughout my career, I’ve worked with global teams, contributed to architecture decisions, implemented CI/CD pipelines, and integrated third-party services like Stripe, OAuth, KYC platforms, and blockchain APIs.
I care deeply about code quality, performance, and clean UX—and I always aim to deliver thoughtful, scalable solutions that solve real problems.
In my free time, I enjoy contributing to open-source tools, reading about AI advancements, and cycling along the California coast.
Let’s build something great together.
