Project Summary

Onix-Systems is the development partner for a fintech startup, designing and building a youth-focused mobile banking app and a web-based admin portal using Java, Spring Boot, Flutter, and Vue.js. They acted as an extension of the client’s team, providing specification support, ongoing development, and QA. The app is integrated with a banking-as-a-service provider and has been connected to the VISA payment system.

Key Challenges

  • Lack of in-house technical expertise
  • Need for a development team to act as an extension of the company
  • Requirement for a Java-capable partner to build and validate a market-test app

Project Deliverables

  • Mobile banking app (Android and iOS)
  • Web-based administration console (Vue.js)
  • Backend services using Java and Spring Boot integrated with a banking-as-a-service provider
  • Referral program and card-control features

Project Solution

Onix-Systems took ownership of the client's application development, implementing backend services in Java with Spring Boot and building mobile frontends in Flutter for Android and iOS. They developed a web-based administration console using Vue.js and integrated the backend with a banking-as-a-service provider for card processing and transactions. The vendor provided an expert to help define specifications, prioritize features, validate the concept, and scaled developer resources (frontend/backend and Vue.js specialists) as needed while providing QA and project management support.

Project Outcome

  • App accepted into the VISA payment system
  • High client satisfaction with vendor expertise and QA; issues were fixed before launch
  • Vendor acted as an extension of the client's team with strong communication and project management
