About Me

Hey there! I'm a product-minded full stack engineer passionate about building scalable web applications that make a real difference.

I've had the privilege of working with amazing teams at Greyfinch and Questbook (YC 21), where I've helped build systems that serve millions of users and process significant transaction volumes.

I love the intersection of great engineering and product thinking — building not just what works, but what users actually need and love to use.
