An Israeli company launched an online service dedicated to helping individuals learn English. Their platform aimed to connect students with English tutors, providing a valuable educational resource. As their business evolved in the edtech sector, they encountered various technical challenges that required expert solutions. 







The client approached our team with several pressing issues and a desire to enhance their platform: 

  • Bug Fixes: Addressing critical bugs in their mail services. 
  • Optimization: Improving platform performance and user experience.
  • New Functionality: Integrating and synchronizing CRM, Admin panel, and databases.
  • Transitioning from Tranzilla payment system to Green Invoice while ensuring data synchronization with the CRM.
  • Adding automated online meeting functionality via Google Meet.
  • Connecting Green Invoice payment system with Airtable for efficient transaction data management. 




The project initially faced significant challenges, because previous developers had limited responsiveness, impeding the onboarding process. The Legacy Code also had difficulties, both frontend and backend had outdated and poorly documented code, necessitating time-consuming code refactoring and reverse engineering. 


Our approach was straightforward: we diligently tackled each task outlined by the client. This comprehensive solution encompassed a range of technical implementations to meet their needs. 


Frontend and Design teams started work around May-June, while the Backend team commenced work in July. As of the time of this case study, the project is ongoing.
