Kinderlime: scaling a platform for 30,000+ daycare centers.

Kinderlime automates private daycare and preschool management in the US: contactless check-in, payments, staff management, enrichment programs. Before they launched, the early childhood education sector was one of the least digitized. By the time they came to us, the platform was already running in 30,000+ centers.

The client had a distributed team (India, California, San Jose) and a working Rails app. But as the business grew, the Rails monolith started to slow down. The goal was to separate the frontend and backend via a REST API and rebuild the frontend based on new mockups.

What we did:

Built a library on top of Redux and Axios that generates API requests, reducers, and response handling. Saved hundreds of lines of repetitive code.

Built a custom form builder from scratch: custom fields, multi-step forms.

Added a CRM with "Insights" dashboards — pipelines, funnels, conversion analytics.

Built an email builder: custom campaigns, mailing list management, automated emails to parents of enrolled children (renders correctly in Outlook, Gmail, Apple Mail).

Tech stack: React, Redux, Webpack, Stripe, CircleCI, AWS, Intercom, React DND. We used Cypress for the first time on this project and achieved 90% end-to-end test coverage.

The result: seamless communication across three time zones, a strong engineering team integrated with the product team, and a modern interface that helped Kinderlime attract even more customers.
