Project Summary

A UAE-based fintech startup hired GLOBALDEV (formerly Steelkiwi) to design and develop a mobile app for digital savings groups and peer-to-peer transfers. After a one-week scoping exercise, the team developed the product using Flutter on the frontend, Django (Python) on the backend, AWS infrastructure, and Twilio for SMS OTP. The engagement started strongly but ultimately went over budget (to roughly $55,000) and was delivered late; the client cited poor communication, inconsistent resource allocation, and weaker frontend work compared with the backend.

Key Challenges

  • Develop a mobile app providing digital savings groups and peer-to-peer transfers
  • Integrate reliably with a third-party open banking API in the Middle East
  • Maintain adequate and consistent resource allocation and experienced frontend developers
  • Deliver on schedule and within the agreed budget with clearer communication and sprint cadence

Project Deliverables

  • Mobile app built with Flutter
  • Backend API and services built with Django/Python
  • AWS-hosted infrastructure and deployment
  • Twilio SMS OTP mobile verification integration
  • UI/UX design deliverables
  • QA testing and test reports

Project Solution

GLOBALDEV conducted a one-week scoping exercise, translated the client's scope into requirements, and recommended a tech stack of Flutter for the frontend, Django (Python) for the backend, AWS hosting, and Twilio for SMS OTP verification. They staffed the project (two backend engineers, two frontend engineers, one UI/UX designer, one QA tester, and one DevOps engineer), developed the mobile app and backend services, integrated with a third-party open banking API, performed QA, and deployed the solution.

Project Outcome

  • App was delivered late (scheduled late-August, completed late-November 2020)
  • Project went over budget from $50,000 to approximately $55,000
  • Backend code was well-structured and praised by the client's CTO
  • Frontend code was considered junior and had to be restructured after engagement
  • Integration with a third-party open banking API encountered significant problems
  • Communication and project management were inconsistent, with missed deadlines

Quality of Deliverables

“Although the engagement started off strong, GLOBALDEV (formerly Steelkiwi) ultimately went over budget and delivered the app late. The client was not pleased with their communication or resource allocation. Also, while they demonstrated strong backend development skills, their frontend development was lacking.”
