Project Overview We are looking for a skilled full-stack developer to build a web platform focused on AI-powered pet photo style transformation and creative image synthesis.
Users can upload pet photos, choose from multiple artistic or themed styles, and generate unique AI-based results. The platform should include a membership system, dual credit/subscription logic, integrated payment gateway, and a modular backend ready for future AI expansion.
Platform Architecture The project will be developed primarily as a web-based platform with responsive design to ensure smooth use on both desktop and mobile devices. The final version should be packaged as a PWA (Progressive Web App) and published on both App Store and Google Play, providing a dual-platform experience without separate native app development.
Scope of Work (Full-Stack Development) Front-End Development ．Pet photo upload interface and generation workflow (Upload → Generate → Result display) ．Style selection and categorization (Artistic, Historical, Trend, Movie themes, etc.) ．“AI Style Transfer – Before/After Comparison” interactive viewer ．Loading animation and visual feedback during generation ．Fully responsive design for desktop and mobile ．User gallery and “My Creations” page
Back-End Development ．User authentication and membership system ．Dual credit & subscription system — both models should coexist and be switchable at any time ．Integrated payment gateway (Stripe / PayPal or equivalent) ．Full front-end control from backend — ability to modify display order, content, labels, and layout directly ．Style management module — add new front-end styles from backend, including generation prompts and sample images ．Cloud-based image storage and management (e.g., AWS / Firebase) ．Admin panel for editing site logo, text, style categories, and prompts
AI & API Integration ．Integrate AI image generation and enhancement APIs (primarily OpenAI; extensible for others) ．Support both text-prompt and image-upload generation modes ．Integrate high-resolution enhancement services such as Gigapixel AI, LetsEnhance, or equivalent APIs ．Modular architecture allowing flexible addition or replacement of AI modules ．Support for multiple language-model APIs (ChatGPT, Gemini, etc.), with admin-side key management
Deployment & Testing ．Deploy to production server (AWS / Vercel / Render etc.) ．Full performance and compatibility testing ．PWA packaging and store submission (App Store / Google Play) ．Delivery of all documentation and admin operation guides
Key Requirements ．Complete web platform (not native apps) ．Responsive + PWA ready for dual-platform publication ．Dual mode credit & subscription system ．Backend-controlled front-end customization ．Addable style modules with prompt + sample image configuration ．Integration of AI generation + image enhancement APIs ．ChatGPT / Gemini API support with editable keys ．Scalable, modular, and maintainable structure
Proposal Requirements Please include the following in your proposal: ．Relevant past projects or demo links ．Proposed architecture and tools you plan to use ．Estimated timeline and pricing ．Experience with AI APIs, payment systems, and credit logic ．Experience with PWA packaging and dual-platform publishing
If you have any suggestions or alternative technical approaches, feel free to include them in your proposal.
