I'm a multi-hat product-minded engineering leader who lives at the intersection of product, infrastructure, and UX. Pragmatic by default: I ship what matters, measure outcomes, cut waste, and keep systems reliably boring where they should be - without slowing teams.
My experience spans from being a Principal Engineer at early-stage startups to CTO position at established products, always with a focus on building the right thing, the right way, while having fun in the process.

"I’ve had the pleasure of working directly with Andrew at Blitz, and he is one of those rare engineers who combines deep technical judgment with strong product instincts. Andrew operates at the intersection of product, infrastructure, and user experience, and that shows in how he approaches problems. He does not just optimize for elegance or novelty. He focuses on what actually moves the business forward. He ships what matters, measures outcomes, and keeps systems simple and reliable where they should be. ... Beyond the technical side, Andrew is thoughtful, calm under pressure, and great to collaborate with. He makes teams more effective without adding unnecessary process or overhead. I highly recommend him. "

Thoughts on software engineering, distributed systems, and building products.
The real multiplier in software isn’t writing more code. It’s judgment: choosing the right problems, avoiding unnecessary systems, and reducing the maintenance burden that slows teams down.

When I'm not shipping code, you'll find me on a squash or badminton court, chasing wind on a kiteboard, driving with no destination in mind, or deep into a gaming session. I love traveling to new places, binge-watching good TV shows (especially Sci-Fi), and winding down with a hookah. I also just like helping people.
