Thach Nguyen

Software Engineer with 3+ years of experience building full-stack products from the ground up. I enjoy working across the stack, taking ownership of problems, and turning ideas into working products. Alongside my professional work, I've built and launched several of my own products, learning through both successes and failures.

I'm currently building ZeniTest.ai, an E2E testing platform for AI-native teams. I'm looking for a startup environment where I can contribute beyond writing code, take ownership, and help build products that people love.
