...date and time range. Users will sign in with a simple username-and-password flow, so the app should ship with a lightweight authentication backend (Firebase Auth, Supabase, or a similar plug-and-play service is fine). All device commands and data packets are already documented in the manufacturer’s GitHub repo; I will share that repo and sample API calls once we start. I’m open to native Swift/Kotlin or a high-quality cross-platform stack such as Flutter or React Native—whichever lets you deliver a responsive UI, battery-friendly background location handling, and rock-solid push notifications. Deliverables: • Source code (iOS + Android) ready for App Store and Google Play submission. • Brief setup guide so I can compile and rebrand in the future...

...and filter options. If you’d like to suggest richer breakdowns or export features later, I’m open, but they’re not part of the first release. Security requirements are strict: data must be encrypted at rest and in transit, all sensitive actions gated by biometric login (Android BiometricPrompt), and every meaningful event captured in an immutable audit trail. Build with modern Android standards (Kotlin + Jetpack preferred), follow OWASP Mobile guidelines, and structure the project so an external security review will pass without surprises. Deliverables • Production-ready Android app (source + signed APK) • Integration with my KYC, banking, and audit-log APIs • Unit/UI tests covering critical paths • Brief security architecture documen...

...cloud microservice if latency is acceptable) and return an easy-to-parse JSON result I can feed into future modules. The interface should feel modern and sleek with clean typography, subtle animations and dark-mode support. You’ll own the full stack—from selecting the best SDK (e.g., Apple Vision, Google ML Kit, OpenCV, or a custom model in TensorFlow Lite / Core ML) to wiring up the UI in Swift/Kotlin or a unified framework like Flutter or React Native, whichever yields the best performance. Source code, build scripts, documented APIs, and a testable release build for each platform are expected at hand-off. I have budgeted roughly £15 per hour; we can break that into clear milestones once you map out the sprint schedule. Let me know your preferred toolcha...

...handling sit at the heart of this project. Users will authenticate exclusively through phone-number verification; no email or social logins are planned for this first phase. A simple, secure workflow—OTP text, automatic read where allowed, and fallback manual entry—will be needed. The interface should feel native on each platform yet share as much code as practical. Whether you prefer Swift with Kotlin, React Native, Flutter, or another modern stack, I’m open as long as the finished product delivers a polished UX and leverages proven real-time engines such as WebRTC, Agora, or Twilio for the call layer. Please include built-in handling for network drops, push notifications for incoming calls, basic call history stored locally or in the cloud, and encryp...

...“Chicken Road Prediction Bot” into a fully working Android app. The concept is simple: feed the app either live video or pre-recorded movement data of chickens near a roadway and have it predict if, when, and where a bird will step onto the road. The platform is strictly mobile and Android is the only operating system I need supported. Here’s what I expect: • A lightweight Android application (Kotlin or Java) with a clean UI that shows a camera preview or data feed and overlays the real-time prediction. • An on-device model—TensorFlow Lite, PyTorch Mobile, or a comparable framework—that can run offline and outputs a confidence score plus an ETA for the crossing. • A simple stats panel logging every prediction with time-stamp s...
