Accelerating Time-to-Market for a Fintech MVP Using ReactJS
A fast-growing UK-based fintech startup aimed to disrupt the digital lending space with a lightweight, mobile-first web application that provided loan comparisons and application tracking. They had investor backing and a concept, but no in-house engineering team to deliver the MVP in time for demo day.
The client needed to launch a fully functional MVP in less than 90 days. Key challenges included:
- Limited internal tech resources.
- Tight delivery timeline
- Mobile-first UI/UX expectations
- Need for scalable architecture for future phases
The client required an experienced, agile team that could hit the ground running and operate as an extension of their product team.
The fintech partnered with Code Elevator to hire a dedicated ReactJS development team. We assembled a remote unit comprising:
- 2 Senior ReactJS Developers
- 1 UI/UX Designer
- 1 Project Manager (part-time)
- 1 QA Engineer
The team collaborated directly with the client’s product lead using Slack, Jira, and Figma.
