...and assign co-moderators. A simple dashboard or in-room toolbar is fine as long as the workflow is intuitive. We can start with this focused feature set—group voice channels plus admin moderation—and keep the codebase modular so we can layer in extras like private messages, file sharing, or end-to-end encryption later if the roadmap calls for it. Preferred stack • Native Android (Kotlin or Java) using WebRTC, Agora, or a comparable real-time audio SDK • Lightweight back-end (Firebase, Node, or another cloud service) for user auth and room state Deliverables - APK and Play-Store-ready bundle - Full source code with README covering build steps, third-party services, and admin feature implementation - Brief test report showing successful m...

...earning channels—completed surveys, rewarded ads, and verified in-app purchases—and shows the live balance on every screen. • User profile management with secure sign-in (e-mail, Google, or similar), avatar, and a running history of earned points. All data must sync to the cloud so users keep their balance if they reinstall. Preferred stack Native Android (Android Studio). Kotlin is ideal, Java is fine. You can propose Firebase, Supabase, or another lightweight backend as long as authentication, realtime updates, and basic analytics are covered. Deliverables 1. Full, well-commented source code and Android Studio project 2. Debug and release APKs ready for Play Store testing 3. Brief setup guide so I can swap ad networks or survey providers later 4...

I want a clear, data-driven picture of how a power system performs when it is heavy on renewables yet faced with unpredictable demand. My primary interest lies in wind energy, but I also plan to integrate a commercial-scale solar PV array whose main purpose is to drive down electricity costs. The job is to build (or adapt) a simulation that captures: • Hour-to-hour variability of a sizeable wind fleet • Output and cost impact of a commercial rooftop or ground-mount PV system • Stochastic or scenario-based load profiles that reflect real-world uncertainty I am comfortable with Python (PyPSA, Pandapower), MATLAB/Simulink, or DIgSILENT PowerFactory—use whatever you feel delivers the most transparent and reproducible results. I will provide resource data...

This project involves developing an embedded graphics application that reads serial data from the RX pin of a QT Py RP2040 microcontroller and visualizes the incoming CPS (Counts Per Second) data in real time on an IL19341 TFT display. The system will continuously capture incoming serial data, process it, and render it as a dynamic graph, enabling live monitoring and analysis of CPS values. The graphical interface will be optimized for clarity, responsiveness, and efficient memory usage within the constraints of the RP2040 platform.

...background and tag it with an emotion label (happy, sad, angry, etc.). • At the end of every 7-day cycle, compile a weekly recap and keep the previous weeks available for scrolling back. • Inside a settings or dashboard screen, display the recap in an interactive bar, pie, or line chart—whichever communicates the distribution of emotions best. Technical notes – Native Android code in Kotlin or Java is fine; please follow modern practices (Jetpack libraries, MVVM preferred). – Data can live in Room or another lightweight local DB. – Feel free to integrate MPAndroidChart or a comparable open-source graph library for the visual. – The code should be modular so future categories (parts of speech, topics) can plug in without rewri...

...built with clean, well-tested code. Your job is to design and implement REST APIs in both Java and Python, wire them up to PostgreSQL for transactional storage, and index searchable content into OpenSearch so that each event is instantly discoverable. The core of the work is twofold. First, map and integrate the existing internal services with the cloud resources I will provide (IAM-secured endpoints, message queues, and object storage). Second, expose that integrated functionality through RESTful endpoints that follow standard HTTP semantics, are documented with OpenAPI/Swagger, and include unit and integration tests. When the work is complete I expect: • A Git repository containing modular, readable Java and Python services. • Docker-ready builds that spi...

...among customer, courier, and restaurant—Firebase or a comparable push-notification service works for me. • Integration with a mainstream payment gateway that supports Indian debit/credit cards and UPI. • Basic admin panel to oversee orders, manage restaurants, run promotions, and pull transaction reports. Deliverables I expect: 1. Production-ready Android APK plus all source code (Kotlin or Java). 2. Clear build/run instructions and minimal test data so I can demo the flow end-to-end. 3. A short hand-off call or document outlining how to add new restaurants, menu items, and promo codes. The UI doesn’t need to win design awards on day one, but it should look polished on modern Android phones and be easy to iterate. My timeline is flexible enough for...

I am building a stateless Go micro-service that will sit between Orange’s push-based feed of live call events and several AI/agent components that must query this data almost instantly for real-time analytics and automated responses. The telecom platform pushes each call record to us in JSON; from the moment it arrives I need to park it in a shared in-memory Redis instance and make it queryable through a tiny HTTP API that will be deployed on Google Cloud Run. End-to-end lookup latency must stay well under the typical network round-trip so downstream systems can react inside the ongoing call. The service must run completely statelessly—every node simply connects to the same Redis and can be recycled at any moment without warm-up. Concurrency and connection handling therefore n...

I have an assignment that requires a full-length sociology research paper. I already have the broad topic in mind; what I need now is someone who can take that theme, shape a clear research question, organise the argument logically, and present the findings in an engaging, academically sound form. Scope of work You will draft the complete paper, structure it with an introduction, literature review, methodology, analysis, conclusion, and a separate Works Cited page formatted strictly in MLA style. The writing must flow smoothly, use sociological theories appropriately, and reference recent journal articles wherever possible. What I’m looking for When you respond, focus on your relevant experience—tell me about the sociology (or closely related) papers you’ve produced...

If you have an alternate stack that meets the requirements and speeds development, let’s discuss; the priority is clean code, clear documentation, and future scalability. I’ve allocated a sensible budget and am happy to structure it across milestones (MVP, admin panel, final polish). The full build should be completed within four...

...creation of multi-week plans, with the ability to edit on the fly. A lightweight account system is required: email or Google sign-in, basic profile storage, and cloud sync for routines and history—nothing more elaborate such as leaderboards or community messaging at this stage. Material-style UI, smooth navigation and offline functionality are important. Please structure the code clearly (Kotlin or Java), document major classes, and supply the final APK along with source in a Git repo so I can continue iterating after launch. If you foresee optional add-ons like nutritional guidance, note how they could be integrated later without major rework....

I’m looking for a single partner who can take my concept from idea to launch on two fronts: a fully-featured Android application and its companion website. Everything should share one clean, secure backend so updates roll out smoothly across both properties.

I’d like a self-contained, Maven-driven demo that shows how a Wildfly 20 Java servlet can talk to three separate mobile authenticators—Microsoft Authenticator, Google Authenticator and Duo Authenticator—and report back the outcome of each challenge. Scope • Focus exclusively on “second-factor” calls: how the servlet initiates a push / TOTP / Duo prompt (the “sending signal” part) and how it parses the success, timeout or failure response that comes back (“receiving results”). • No UI polish is necessary; a simple JSP or REST endpoint that prints JSON or plain text is fine as long as the code flow is clear. • Keep the sample lean but complete: working source, config files, and any required libraries or REST c...
