Mentorflow - Founder

Full-stack SaaS platform for instructors and training studios (martial arts, languages, fitness) launched as a side project. Worked full-time for 5 months to build the MVP, which organically grew to serve 10 invite-only clients with 1,500+ active users.

Built multi-tenant architecture with Ruby on Rails backend, React web app, and React Native mobile apps for iOS/Android. Integrated Stripe for subscription billing, Zoom SDK for virtual classes, and leveraged OpenAI API for AI-powered features like lesson planning and student recommendations.

Currently maintained on weekends only, with deployment on AWS infrastructure using S3 for file storage, CloudFront for content delivery, and Redis for caching.
