OCTB
A language-learning platform connecting tutors in Latin America with students in North America.
- The problem
- The platform built by a previous agency was unstable and poorly structured. Every change risked breaking something else, while students and tutors depended on it daily.
- Our decision
- Fix the critical bugs that students and tutors felt first, then rebuild the architecture underneath, without ever stopping the lessons.
- What we built
- A stabilised core with a rebuilt architecture. Lesson booking that matches tutor availability and student requests with a scan-line algorithm. Stripe subscriptions plus pay-as-you-go minutes via Stripe and PayPal; no card data stored on the platform.
- The result
- A stable, self-sufficient platform with over 5,000 active users. Integrations with HubSpot, Slack and Mixpanel were added along the way.
