How I Build

Boring is Better

I prioritize predictable, battle-tested technologies over the latest trends. Complex architectures are only introduced when strictly necessary to solve specific scale problems.

Design for Failure

Systems will fail. I build with defensive boundaries, comprehensive monitoring, and aggressive degradation paths so that localized issues don't cascade across the platform.

Product-Minded

Code is a means to an end. I focus heavily on latency, cost-efficiency, and user experience, ensuring that backend decisions align directly with business goals.

Let's build something great.

I'm actively looking for full-time roles and taking on select freelance projects. Whether you're hiring an engineer to scale your team or need serious backend expertise for your product, let's talk.
