Fintech platform for Islamic Finance

RizqX came to us with a web platform built in Plasmic that they wanted to keep. We integrated with it, took over their development and release pipeline, built their Flutter app for iOS and Android, and a year later moved them off Plasmic altogether.](https://www.webfluentia.com/portfolio/rizqx) // Questions ## Questions
What does a project cost? Websites start from 12,000 THB. Custom platforms range up to several hundred thousand baht depending on scope. You get a fixed quote after the first call.
Can you take over an existing codebase? Yes. We start with a short review of the code, hosting and deployment, then tell you what we would keep, fix and replace before you commit to more.
Which technologies do you use? Mostly TypeScript across the stack, PostgreSQL for data and Cloudflare or Google Cloud for hosting. We choose well-supported tools unless there is a clear reason not to.
Do you build mobile apps? Yes. We build mobile apps in Flutter, so one codebase runs on both iOS and Android, and we handle publishing to the App Store and Google Play. RizqX and the World GPS Tracker fleet app are two examples.
