The copy is finished and the section-by-section wireframe is already mapped out: nav, hero, how-it-works, why-we’re-different, call-to-action, and footer. I now need the whole thing brought to life in Framer. I need a simple single-page website built in Framer. The full design is already done — colors, layout, copy, and section structure are all specified. Your job is to build it cleanly in Framer and publish it. The page has seven sections: sticky nav, hero with dark green gradient background, trust strip, how it works with connected step design, why we are different with three cards, who it is for with a four-card grid, full-width CTA section, and footer. Color palette is provided — deep forest greens, warm cream section backgrounds, lime green accents, dark g...
I have a digital recipe guide that needs to start earning right away, and I want it selling on three fronts—Etsy first, then Gumroad and Payhip. Your main mission is to wire in a rock-solid affiliate program on each platform that pays a 50 % commission on every confirmed sale. Getting that referral engine right is the priority, but the rest of the build-out has to be airtight too. Here’s the flow I’m aiming for: you open fresh shops (or optimise the current placeholders if faster), hook up PayPal and card payments, drop in the product files, and ensure the listings look native to each marketplace. Before upload, swap the price text inside the PDF to the new figure I’ll supply—no design overhaul, just that quick update. Once the shops are live, I need ...

...essential because the app will often run in the background. Deliverables • A self-contained React Native module (TypeScript or modern JS) that wraps all BLE operations and exports easy-to-use hooks or callbacks. • Native bridge code where needed (Swift/Objective-C for iOS, Kotlin/Java for Android) so the same JavaScript API works on both platforms. • Clear documentation and a short demo screen that prints live weight values, connection status, and battery level if the scale exposes it. • Unit tests or a simple test script proving that the module reconnects automatically after signal loss and remains within ±200 ms latency for updates. Acceptance criteria will be a test run with an actual Acacia scale on my end: pairing, live readings, and...
...playful interactive activities. Each lesson ends with an interactive quiz that captures answers, awards instant feedback, and records the result. A simple progress-tracking module is essential: learners must see how many lessons they have completed, current quiz scores, and weekly streaks; teachers or parents should be able to glance at the same data on a lightweight dashboard. Think Firebase or an equally quick cloud back-end for syncing, but I’m open to the stack you prefer as long as the data stays secure and the UI remains snappy on entry-level Android phones. Core deliverables (acceptance criteria): • Android APK + source (Kotlin or Java) compiled against the latest stable SDK • Audio-first lesson player with play / pause / seek and buffered stream...
...rounds are observed. All I want on my side is a simple interface—command-line, lightweight webpage, or even a desktop window—where I see the last few rounds, your predicted colour for the upcoming one, and a confidence score. If you prefer, the prediction can simply be printed to the console; slick visuals are not a priority, accuracy and speed are. Please include: • A brief description of the logic or model you use (statistical analysis, machine learning, pattern recognition, etc.) • Well-commented source code and instructions so I can run it on my own machine without extra licences • A quick read-me that explains how to connect to the data feed or swap it out should the game’s endpoint change I will test by running the program...
...it has to be, but polished enough to feel professional. Core workflow • Patients open the app, review each doctor’s profile (photo, specialty, brief bio, available hours). • They pick an open slot and confirm the booking. • A push notification reminds them as the appointment approaches. That’s the heart of it. I am open to your preferred stack, yet an Android-native build in Kotlin or Java via Android Studio will likely keep things straightforward. If you already have experience wiring notifications through Firebase Cloud Messaging—or a comparable service—please mention it. Deliverables 1. Full Android source code with clear project structure. 2. Debuggable APK for testing and a signed release build. 3. Short hand-off guide ...

...page in create mode. • Only personal information (name, date of birth, ID numbers, etc.) has to be filled. Basic validation—presence checks and simple format rules—is sufficient; anything more can stay out of scope for now. • The end result should feel native: once the API call succeeds, the user sees the customer screen with every mapped field in place and can immediately continue the usual onboarding process. Deliverables I expect: 1. Integration code (Java / PL-SQL wrapper or preferred Flexcube extension) committed to a Git repository. 2. Mapping document that shows each JSON field and its corresponding Flexcube column. 3. Simple test script or Postman collection proving the end-to-end flow. 4. Brief deployment notes so our op...
I’m launching a new brand and need a crisp, minimalist word-mark that can live comfortably across website headers, social banners, and print.

If you prefer particular type tools or grids, let me know; otherwise, I’m open to your process. I’ll review portfolios as they ...
I need a straightforward food-ordering website that lets visitors browse and place orders for Italian, Chinese and Mexican dishes from a single, clean interface. A built-in ordering form should handle item selection, quantity, delivery details and a confirmation screen. An events page will highlight upcoming tasting nights or seasonal specials, while a photo gallery will showcase signature dishes to whet appetites. Simplicity matters more than bells and whistles: basic account creation and a lightweight check-out flow are enough, provided the path from menu to order submission is friction-free. A compact admin area for menu edits, order monitoring and event updates will keep day-to-day management easy. Core deliverables • Responsive website covering the three cuisines listed above...

...active D-U-N-S number and all legal details—in Apple’s Developer Program. What I need now is a seasoned guide who can walk the account from “not yet started” to “approved and live” with as little friction as possible. Your main focus will be on the new-account workflow: completing the online forms, verifying the D-U-N-S data, handling Apple’s phone or email confirmation, and making sure the enrollment payment is processed successfully. Once the account is enabled, I would also like a concise rundown of the primary roles and permissions in App Store Connect so the internal team understands who should be Admin, App Manager, etc.—no deep training, just a quick, practical overview.

...screen reader) is active. Here is what I expect: • Add or correct contentDescription attributes, accessibility labels and hints so that controls are spoken in a logical order. • Ensure state changes—errors, success messages, toggles—are conveyed via accessibility events without relying on visual cues alone. • Keep visual layout untouched; all work should sit cleanly in the XML and Kotlin/Java layers. • Provide a short video or emulator capture showing TalkBack reading through a typical form flow, plus the updated source files or a merge request.

I maintain a Java-based backend that exposes a small REST interface for sensor and other device data. A few legacy issues are breaking current GET and POST calls and I also need several new endpoints added. Each confirmed bug you resolve is paid at ₹1,200, and the same rate applies if you prefer to log time hourly instead. Scope • Diagnose and fix existing errors in the REST layer, services, or related model classes. • Add clean, well-documented GET and POST endpoints so devices can reliably push data and consumers can pull it back. • Ensure responses follow our current JSON schema and return the correct HTTP status codes. • Provide concise unit or integration tests that demonstrate each fix or new endpoint working end-to-end. Acceptance criteria A pu...
I’m rolling out a new feature that touches both ends of our stack. On the backend we run Java 21 with Spring Boot micro-services, alongside a small Node.js/Python layer that exchanges events through Kafka. The frontend is split between an older Angular module and a newer React interface. The job is to design and code the complete feature, wiring it cleanly into every affected service and UI surface. You will: • Extend (or create) the relevant Spring Boot endpoints, making sure they publish and consume the right Kafka topics. • Update the Angular dashboard and the React SPA so the user experience is seamless across both frameworks. • Keep code idiomatic, unit-tested, and pushed to our Git repo via pull requests. Acceptance criteria • All API tests p...
