Full-Stack Mobile Developer for App (iOS & Android)

I am looking for a talented mobile app developer (or small agency) to build Pinvera, a community-driven social mapping platform. The app allows users to report and "pin" real-world social encounters to a map, categorized by specific archetypes (Karens, Chads, Legends, and Safety Warnings). The app features a robust moderation system and a gamified experience where users earn tokens, increase their trust score, and compete on a global leaderboard. Key Features & Functionality 1. User Authentication & Profiles Sign-up/Sign-in via Email, Google, and Apple ID. User profiles displaying "Trust Score," "Level," and "Total Tokens." Streak tracking (e.g., 0-day streak) to encourage daily engagement. 2. Interactive Map Interface (Core Feature) A real-time map view (Google Maps or Mapbox integration). Visual "pins" based on the category of the encounter. Filter system to toggle visibility of different pin types (Karen, Chad, etc.). "Current Location" centering and search functionality. 3. Encounter Reporting ("Add Pin") User-friendly form to submit encounters. Categories: Karen: Annoying or entitled behavior. Chad: Positive or funny encounters. Legend: Wholesome or helpful encounters. Warning: Scams, safety alerts, or warnings. Submission Details: Title, Description, Category selection, and Geo-location (automatic or manual). 4. Moderation & Pending System All submitted pins must go to a Pending Queue. Admin/Moderator capability to review, approve, or reject pins before they appear on the public map. A "Pending" tab for users to track the status of their submissions. 5. Gamification & Leaderboard Token System: Users earn tokens for approved pins. Trust Score: A leveling system (Level 1, 2, etc.) based on the accuracy and frequency of reports. Leaderboard: A dedicated "Board" tab showing top users ranked by Tokens, Trust, or Activity. 6. Categorized Feeds Dedicated tabs for "Karen Sightings," "Chad Encounters," "Nice Legends," and "Warnings." Feeds should include "Most Reported" trends for the week (e.g., "Most reported: Phone scams this week"). Technical Requirements Platform: Cross-platform development (Flutter or React Native) to ensure 100% feature parity on iOS and Android. Backend: Firebase (Firestore, Auth, Functions) or a Node.js/PostgreSQL setup. Geolocation: Deep integration with GPS and mapping APIs. UI/UX: I have existing high-fidelity wireframes/screenshots. The developer must be able to replicate the clean, modern aesthetic shown in the designs (rounded containers, soft shadows, and specific iconography). Timeline & Milestones Phase 1: Backend setup & User Authentication. Phase 2: Map integration & Pin submission logic. Phase 3: Admin Moderation panel & Pending flow. Phase 4: Gamification (Tokens/Leaderboards). Phase 5: QA Testing & Deployment to App Store/Google Play. How to Apply Please provide: Examples of previous map-based or social networking apps you have built. Your preferred tech stack for this project. An estimated timeline for an MVP (Minimum Viable Product).

Android app similar to J.D. app

I want to find someone who built an android app similar to J.D. app before. I need to build an android app which has similar functionality to J.D. app. It might have different UI/UX but it should have most of the functionality as J.D. has.

Android Employee Activity Keylogger

I need a discreet Android application that records employee device activity for compliance purposes. The app must log every keystroke, track websites visited in any browser, and chronicle foreground app usage with accurate timestamps. At user-defined intervals these three data streams should be consolidated into a clear report and sent automatically to a chosen email address. The service has to survive reboots, remain hidden from casual discovery, and run smoothly on Android 9 through 14 without demanding root access. Battery and data consumption should be minimal. A single first-run screen where I can enter SMTP credentials, reporting frequency, and perhaps an optional keyword filter is sufficient—after that, the interface can vanish. Deliverables • Release-ready APK plus fully commented source code • Straightforward setup guide suitable for a non-technical manager • README detailing the permissions used and collection methods Acceptance criteria • Keystroke, website, and app-usage logs arrive via email on schedule with correct timestamps • No visible notifications or icons after initial configuration • Service restarts automatically after a reboot or update

Simple Android OBD-II Diagnostic App

I need an Android application that pairs with an ELM327 Bluetooth OBD-II adapter and performs a very limited set of diagnostic tasks. The goal is to give me a clean, lightweight tool rather than a full-blown scanner. Core behaviour • When the user taps “Connect”, the app must discover and bond with a standard ELM327 device and keep the link alive. • Once connected, it should read live PIDs for engine RPM and battery voltage/status and refresh them smoothly on screen. • A single button should read any stored trouble codes and, when pressed again, clear them. No additional graphs, logging or fuel-consumption features are required. Tech notes I am comfortable with you writing the project in either Kotlin or Java inside Android Studio; please use the standard Bluetooth APIs (or a lightweight library if it speeds development). PID queries can be hard-coded—no dynamic command builder is necessary. The interface can be minimal: two large numeric fields for RPM and battery, plus the read/clear button. Deliverables Full Android Studio project with well-commented source. One signed release APK I can load directly onto my phone. A short README explaining how to pair the adapter and which PIDs you used. Acceptance I will test by pairing the app with my own ELM327 dongle; connection must succeed within 10 seconds, RPM values should update at least twice per second, and clearing codes must return the standard success response. If this sounds straightforward to you, let me know your timeline and any questions you have.

MERN Developer

We are looking for a senior developer to help us finalise and consolidate a number of projects which are 75% complete. We expect this to be an ongoing, monthly paid role and so the budget is on that basis. We have a legacy system that, whilst functional, is outdated and needs the functionality migrating/replicating in our new environment. The work will include refactoring, adding routes and connecting multiple interfaces to complete the job. You will need to have an understanding of complex data structures to ensure that migration and CRUD functionality is accurate to serve various interactions of the project. Lastly, the platform has a companion application that is built and compiled in EXPO. This will need attaching to the new migration, rebuilding and deploying to the stores appropriately. Therefore the following experience is necessary **Key Responsibilities:** - Develop new features and enhance existing functionality for our directory website using the MERN stack (MongoDB, Express.js, React.js, Node.js, Next.js). - Utilise trunk-based development practices to ensure smooth and timely integration of code into the main branch. - Work collaboratively with other developers to resolve conflicts and merge changes efficiently. - Perform regular performance and bug-fixing tasks to ensure optimal website performance. - Write clean, maintainable, and efficient code, following best practices and industry standards. - Participate in code reviews to maintain code quality and provide constructive feedback. - Continuously improve and upgrade the software to keep up with the latest advancements in technology. **Required Skills and Experience:** - Proven experience as a MERN Stack Developer. - Strong understanding of trunk-based development and its best practices. - Prior experience working in an agile environment with regular sprints. - Proficiency in MongoDB, Express.js, React.js, and Node.js. - MUST MUST be proficient with Docker and build architectures. - Familiarity with version control systems, particularly Github and Github Actions. - Excellent problem-solving skills and attention to detail. - Strong communication skills and the ability to work collaboratively in a team environment. - Ability to manage multiple tasks and deadlines effectively. **Nice to Have:** - Experience with DevOps practices and tools. - Knowledge of serverless architecture and cloud platforms. - Familiarity with continuous integration and continuous deployment (CI/CD) pipelines. - Typescript experience. If you're after a easy going developer role where there's more work then we can get through then please let me know. No agencies and please only apply if you're used to throwing code out from ticket reference branches - we want to be pushing/building multiple times a day in some situations. Please please please do not apply if you're a junior or mid dev - this requires an individual to undergo a steep learning curve and drive the migration to finalisation. Also - the individual needs to work on the project full time until complete - this is not something that can be done in an hour a day.
