Work

We build. We measure. We prove it.

Every engagement ends in numbers a business owner cares about: lower costs, faster pages, more customers. Here is the evidence.

Yuzi Care · 2023-2026

From a Wix rebuild to the engineering behind an award-winning care platform

Yuzi Care is a tech-enabled, AI-powered perinatal care platform that matches families with vetted birth and postpartum providers. Our work together started in 2023 with a rebuild of their Wix site: 3.5x lower monthly costs and a 40% Lighthouse gain. It grew into an ongoing engineering partnership, with our founder Harper Foley as the primary engineer behind the platform as Yuzi went on to win the 2026 SXSW Pitch.
