...experience should be straightforward: learners open the app, browse or search for lessons, tap to watch, and, when I go live, receive a push notification and join the stream in real time. Adaptive quality switching, standard playback controls, and an intuitive category structure are essential so that students on any connection can keep up. Android is the immediate priority, yet I’d like the architecture kept modular so adding an iOS or web front-end later will be painless. To keep uploads and live scheduling manageable, I’d like a simple web-based admin panel or Firebase console integration—whichever fits best—to let me add new videos, set thumbnails, schedule lives, and view basic analytics. Deliverables • Production-ready Android app (.aab/.a...

...production-ready circuit and compact PCB built around the ESP32-C6 for an IoT device that must run efficiently on both a small solar panel and a rechargeable battery pack. Wi-Fi connectivity is mandatory, and every part of the design has to prioritise ultra-low power consumption so the unit can sit in deep-sleep most of the day yet still wake to trigger a miniature solenoid valve on command. Power architecture The board should accept solar input (≈5-6 V) and seamlessly switch to a lithium cell when sunlight is unavailable. Please integrate an MPPT-style charge controller, battery protection, and a low-loss power-path so the ESP32-C6 always sees a stable 3 V3 rail. Current draw during sleep should stay well under 30 µA.

I want to replace paper timesheets with an automatic clock-in / clock-out system that identifies staff by face the moment they pass our main entrance camera. As soon as a recognised face crosses the frame, the system should log the arrival or departure time against that employee’s profile and store the record in an attendance database I can export to CSV or Excel. Architecture is open: I’m comfortable with a cloud, on-prem, or hybrid deployment—whichever you feel offers the best balance of accuracy, speed and privacy given a single entrance camera. No links to my HR or payroll software are needed for now, so a self-contained dashboard or lightweight web portal that lets me view, edit and download daily, weekly and monthly reports is perfect. Key deliverables ...

I’m building a dedicated Android application and web application that lets users browse and interact with a large, well-structured library of questions. The core idea is simple: present questions clearly, let users filter or search them with ease, and ensure the whole experience feels fast and native on any modern Android device and web search platform. Clean architecture, offline-friendly data storage (Room/SQLite or your preferred solution), and a responsive Material-compliant UI are must-haves. I’d like to see a detailed project proposal from you.
