A fully custom, owned platform build. Estimation, milestones and payment schedule at a blended rate of $22 / hour.
Custom stack: Next.js front end, Node/Postgres back end, custom admin/CMS for no-developer content editing, Stripe + WiPay payments, and interactive lesson activities. The approved interactive demo is the design reference, which lowers design hours.
