About me

I'm an Engineering Manager with 8+ years in software development and system design, passionate about building great solutions and growing the people who build them. I've led teams through challenging migrations, high-stakes production incidents, and full system rewrites - and I still love getting into the technical details when it counts.


I graduated in Mechanical Engineering from the National University of Singapore, then spent a year in Stockholm doing design engineering at a fast-paced startup before pivoting into software. That background gives me a different lens on problem-solving that I bring to every challenge.


I keep a close eye on AI tooling — applying what actually moves the needle and sharing those tools with my team.
