If you do much of anything online, you've probably run into code I wrote. Working with a variety of bootstrapped and funded B2C startups, formerly Sr SDE at Amazon.
Most of my value add is in helping people cut through the noise and figure out what they truly need to build to get their business to the next level. There's almost always a simpler way to build your product than the one you're thinking of.
Professionally, I've architected and built everything from large-scale distributed systems for Amazon to complex Rails apps for your average startup. I've even built WordPress sites for specialized content shops, mostly to see what WordPress could do these days.
