Project Title: AI-Based "Digital Arrest" Scam Detection System (MVP) Project Overview: I am looking for an AI/ML developer to build a functional prototype of a security system designed to detect "Digital Arrest" scams. The system needs to analyze video and audio inputs in real-time (or near real-time) to identify deepfakes, threatening language, and fake law enforcement visuals. Key Features Required (The Scope): I need a desktop-based prototype (Python/Streamlit or similar) that can process a sample video feed or live webcam input and perform the following: * Audio Threat Detection (NLP): * Transcribe audio in real-time (using OpenAI Whisper or Google Speech-to-Text). * Detect specific scam keywords/intents (e.g., "money laundering," &quo...

I need a clean, professional website that presents our intellectual-property services at a glance and builds instant trust with prospective clients. The site will be primarily informational, so the content flow must guide visitors through three core sections—About the Firm, Our Services, and Contact Us—culminating in a Contact page equipped with real-time live-chat support. The design prototype is ready in Figma and currently published on a temporary Figma domain. We are now moving into the development and pre-launch phase before investor presentations. Design should be responsive, fast-loading, and WCAG-friendly, with a CMS back-end (WordPress, Webflow, or similar) that lets me edit copy and add new service descriptions without touching code. Deliverables • ...
I’m pu...device and take turns • Simple sound effects and upbeat background loop (royalty-free is fine) • Exported builds and source code ready for both iOS and Android I’m open to Unity, Flutter, Godot or another engine you’re comfortable with, provided the final APK/IPA installs cleanly and runs smoothly on current devices. UI can stay playful and 2D; no heavy 3-D work required. Once a working prototype is on TestFlight / an Android APK, I’ll play a full round to confirm: 1. All board spaces trigger the correct prompts. 2. No crashes or freezes after 30+ minutes of play. 3. Audio toggles and rule screens operate properly. If that passes, we polish visuals and wrap up. Let me know which tech stack you’d prefer and a rough timel...
...Quick links to manuals, installation guides, and supplier pages • Guest checkout plus the option to create an account (payment gateway can be stubbed with dummy data for now) You’re free to recommend lightweight databases, ready-made UI kits, or headless CMS options as long as onboarding new products remains straightforward for a non-technical operator. Delivery expectations 1. Clickable prototype for feedback on layout and flow 2. Fully functional Android (APK) and iOS (TestFlight) builds 3. Source code pushed to a private Git repository with clear setup instructions 4. Brief hand-off call or screen-share to walk me through deployment and basic maintenance If this pilot phase goes well, we’ll scale up with more advanced inventory, real payment int...

I’m building a product page that lets shoppers grab the item, spin it in any direction, and zoom in on details—all with no autoplay.

I already have a clickable, rough-draft prototype of the product and now need to take it live. The immediate focus is translating that prototype into a production-ready React-Native application for both iOS and Android. While the mobile build is underway, I also want to formalise the visual language of the product—colours, type, iconography, tone—into a concise brand style guide that my team can reuse across every touchpoint. Certain features in the roadmap rely on AI (for example, smart content recommendations and intent-based search). If you have preferred libraries or services—TensorFlow Lite, OpenAI, LangChain, or on-device ML kits—bring them into the discussion; speed of delivery is key. I’m comfortable with AI-assisted tooling (GitHub Co...
...destinations, experiences, and eventual bookings. Core to the experience will be an intuitive interactive map that lets users zoom, filter, and click through to destination pages without feeling lost in layers of navigation. Here’s what I expect to receive: • High-fidelity Figma (or Adobe XD/Sketch) designs for homepage, destination listing, single destination, and blog template • A functional prototype showcasing the interactive map and basic page transitions • Style guide covering colors, fonts, button states, and iconography The designs should be responsive from the outset, geared toward mobile-first but just as striking on large screens. If you have suggestions for subtle animations, parallax sections, or ways to weave in user-generated content la...
I have a working prototype of a messaging layer that sits directly on top of Gmail. The backend (Go micro-services on GCP, MongoDB Atlas) is solid enough for now, but the React frontend needs love before I can call the product “production-ready.” Here’s where I need you to focus: - UI/UX problems • Layout and design • User interactions - Performance issues Your first task is to audit the existing React 18 codebase, isolate the pain points above, propose fixes, then implement them. I want the interface to feel native inside Gmail—clean, intuitive, and fast, with bundle size and render times kept in check. Tech context you’ll touch: React 18 with hooks and Context API, Go services served via Cloud Run, MongoDB Atlas, GitHub for v...
...smart release path. Key goals • Build a core loop that makes “completing levels” feel uplifting rather than grindy. • Craft an art direction that balances calm, eye-catching aesthetics with lightweight performance. • Layer in subtle narrative beats so each cleared level feels like one more step in the player’s healing arc. Deliverables I’d like to see as we move forward – A playable prototype of the first few levels that demonstrates mechanics, controls, and mood – A concise design document covering the full level roadmap, art style guide, and planned monetisation (if any) – Iterative builds leading to a vertical slice suitable for early testing and publisher or store submission I respond quickly and give...

...primary focus is the user interface—layouts, typography, color palette, iconography, and micro-interactions—so users feel the upgrade immediately when they open the app. You’ll receive access to the existing pages and a brief outlining core flows, branding cues, and any technical constraints. From there, I’d like high-fidelity mock-ups (Figma or Sketch preferred) for each screen plus a clickable prototype to validate the new look and ensure consistency across breakpoints. Acceptance criteria • Every current screen re-imagined with a modern, minimalist aesthetic • Responsive behavior illustrated for mobile, tablet, and desktop views • Design system file with components, spacing, and typography tokens • Handoff package ready for...
I already have a clickable prototype of an end-to-end Android point-of-sale application. The next step is a high-fidelity UI that strictly follows Google’s Material Design 3 (Material You) principles without adding any custom brand palette—dynamic color, updated typography, shape tokens and motion patterns should all reflect the standard guidelines. Scope • Every screen in the prototype—from login and dashboard to payment processing and the more advanced flows—is included. Nothing is out of scope. • Target platform is Android only; layouts must accommodate phones and 7–10" tablets in both portrait and landscape. Deliverables 1. A complete Figma (or comparable) file with components, styles, and responsive break-points. 2. ...
