I need a clean, lightweight Android application that showcases every SKU in our pharmaceutical line. The core of the app is a product catalogue where users can: • instantly search any medicine by name • filter results by therapeutic category All product data will be supplied in CSV or JSON (whichever you prefer) and displays should follow our existing brand guide so the transition from web to mobile feels seamless. The second pillar of the project is an in-app AI chatbot. It must handle everyday customer inquiries and intelligently recommend the correct medication based on symptoms or conditions the user types in. No dosage advice is required at this stage, but the model should be built so we can extend it later. You may plug in an established service such as Dialogflow, Azure Bot Service, or your own fine-tuned LLM—whichever gives us fast, accurate responses without forcing users to leave the catalogue. Key expectations 1. Native Android build (Java or Kotlin). 2. Modern, intuitive UI that loads quickly even on low-end devices. 3. Offline caching of catalogue data with a simple sync routine. 4. Secure, well-documented codebase handed over via Git on completion. 5. Short demo video plus installation APK for testing. Once the full APK and source are reviewed, I’ll run a test suite: catalogue search and filter must return correct SKUs within two seconds, and the chatbot should pass a set of sample condition prompts with at least 90 % accuracy. Everything else—push notifications, price sorting, dosage details—can remain optional for a later phase.
