Hello, world
A developer from New Jersey, building in public and for the coast.
I'm KJ. I founded Flowstate Labs and Cape May Web Design, and co-founded Contrax, a DeFi protocol on Arbitrum.
I care about clean, commented code and quiet interfaces — software that helps a business grow its presence, or a team actually get the work done. I've shipped with remote, freelance, and founding teams for years.
When I'm not at the keyboard, I'm in the gym, on the basketball court, or out seeing some new corner of the world. Say hello on LinkedIn.
