Co-founder · Full-stack builder
Designs and builds fast, brand-forward websites and web apps for clients — from first concept to launch. Turns rough ideas into polished products people actually want to use.
A defined deliverable, timeline, and price — design, a build, or an AI feature, shipped start to finish.
We plug in alongside your team on an ongoing basis — sprints, standups, and a shared roadmap.
We map your workflows, flag automation opportunities, and hand you a prioritized roadmap — no build commitment required.
Monthly access to senior design, AI, and engineering judgment — architecture reviews, hiring help, technical strategy.
