• Description We have a small Python script which needs to be put on the server-side as an API. Excluding the GUI code and comments, the script has about 750 lines. You will be given a VPS, which the API will allow downstream applications to call the engine for data comparison. We need multiple real-time endpoints for downstream applications. For testing purposes, we will set the maximum to 3 for now. Ultimately, it can be scaled to an unlimited number of real-time comparisons. I suppose we will have multiple copies of the comparison code on the same/different servers, but with three REST API endpoints. Hence, the Python script will be split into server and client-side code. As there are multiple data points to be compared with, we are thinking that the web app will first initiate...

I need a straightforward Android application that lets my customers send money to me by bank transfer. After signing up or logging in with the classic username-and-password flow, a user should be able to choose an amount, see (or pre-fill) my banking details, and push the payment through an integrated bank-transfer API. Security is critical, so the credential flow must be encrypted end-to-end and the transfer requests signed or otherwise verified to prevent tampering. A lightweight backend—REST or Firebase Cloud Functions is fine—can manage authentication, session tokens, and payment-status webhooks. Please deliver: • Full Android Studio project (Java or Kotlin) • Secure username/password authentication flow • Bank-transfer API integration with success/...

The interface should feel classic and simple—think tidy screens, large touch targets, and minimal ornamentation—yet leave room for our logo and a primary brand colour. The build has to expose at least one clean way to push daily summaries to external accounting software (REST, webhook, or a small middleware modul...

I have a production mobile app built in Flutter that now needs two things at once: a smooth migration to React Native and a fully-featured AI layer.

Here’s what I need from you: • First, review the existing Flutter project and outline a clean, low-risk migration path that keeps both iOS and Android parity. • While migrating, weave in a new AI layer that boosts user experience, adds meaningful functionality, and sharpens overall performance. I’m interested in API-based models that support chat-style assistance and data-driven recommendations; prompt design and runtime optimisation will be part of the job. • Once the Reac...
