About Me

I'm a startup veteran and full stack developer in San Francisco

I love developing—not only bringing new web products to life, but the entire process of planning and implementing ideas, exploring markets, strategizing about the macro impact while resolving all the micro-decisions that elevate products from good to great. Currently I am working with Vue.js and loving the SPA architecture.

When I step away from my computer I enjoy hiking around the Bay Area, traveling the world (boo, COVID!), charcoal drawing, grilling and building elaborate LEGO sets.
