I’m a fullstack engineer focused on building high-performance and sustainable web applications that hold up as products and teams grow. I specialize in design and implementation of core application mechanisms tailored to complex business requirements.

I’m comfortable going beyond existing libraries when they get in the way, and over the years I’ve developed a strong intuition for when custom solutions lead to simpler, more reliable systems.

Outside of work, I explore programming across the stack—from operating systems and compilers to web servers, game engines, and graphics. Understanding how each layer works makes it easier to design systems that are robust, scalable, and predictable.

I’m currently a Lead Fullstack Developer at Sabre, where I design and implement critical system components, including a component library, API integration layer, and a state machine driving the flight reservation flow.
