Ren Hwa (Zack) Low

Software engineer specialising in AI, with experience across multiple domains: agentic systems, computer vision, generative AI and speech processing. Strong programming fundamentals and full-stack experience.

I work from first principles: I take the time to understand the problem deeply and how the ideal solution might fit into the bigger picture. I'm comfortable owning ambiguous problems end to end, from discovery with stakeholders to evaluation and deployment.

Solving problems is what I do. Writing code is only one of the ways I do it.

Get in touch

I'm open to roles where I can own a problem from the first conversation with users through to production. If that sounds like your team, send me an email.

Or ask me out for coffee. I'll probably end up talking about grind size.
