Mark Erwin Serna, Senior Full Stack Engineer
Mark Erwin Serna

Hi, I'm Mark. I turn ideas into working software.

Senior full stack engineer with eight years building for the web. Frontend-led in React and TypeScript, with full-stack range across Go, Node.js and AWS. I have extensive experience building and scaling SaaS products, from early-stage features to production applications. Currently at Audinate, and hoping to do that work from Australia one day.

Let's work together.

I'm open to software engineering roles in Australia. It's something I've been working toward for a while, so I'd be genuinely grateful for the opportunity. Thank you for considering me.
