Full-Stack Developer For Web App

Hello there,

About the Project
We’re building an ad-supported online image upscaler that runs fully in the browser (Photopea-style). Users will be able to upscale unlimited images directly on their device, while the platform monetizes through a mix of video ads, banner ads, and Google sign-in personalization. The core product is simple for the end user, but technically it requires a smooth integration of AI models in the browser, Firebase authentication/storage, and Google Ads monetization.


Role Overview
We’re looking for a Full-Stack Developer with experience in AI model deployment for the web to help us build, launch, and optimize this platform. You should be comfortable moving quickly from MVP to production, and have a solid grasp of performance, scalability, and ad tech integrations.


Responsibilities
• Build a clean, responsive front-end for image upload, preview, and upscaling.
• Integrate AI upscaler models (Real-ESRGAN lite or similar) into the browser via WebGPU/WASM/ONNX Runtime Web.
• Implement Firebase for:
• Google sign-in (auth)
• Basic user data storage & usage limits (if needed)
• Configure Google AdSense / Google Ad Manager for video ads + banner placements.
• Optimize performance: tiling, caching, and progress bar simulation.
• Deploy to production (likely Vercel/Netlify + CDN for models).
• Ensure the app is secure, bot-resistant, and scalable.
• Provide guidance on best practices for ad integration, analytics, and future monetization options.


Requirements
• Proven experience as a Full-Stack Developer (React/Next.js or similar).
• Strong knowledge of JavaScript/TypeScript and client-side libraries.
• Experience with AI/ML models in the browser (ONNX, TensorFlow.js, WebGPU, WebGL, or WASM).
• Familiarity with Firebase (Auth, Firestore, Hosting).
• Understanding of Google AdSense / Google Ad Manager integrations.
• Solid grounding in performance optimization and scalable web app design.
• Ability to work independently and move quickly from MVP to production.


Nice to Have
• Experience with SEO optimization for high-traffic tools.
• Knowledge of ad-tech best practices (fill rates, CPM optimization, targeting).
• Previous work on ad-supported free web tools.
• Understanding of basic security/anti-abuse measures (CAPTCHAs, rate limits).


What We Offer
• Flexible, remote role.
• Opportunity to help build a high-traffic, ad-driven platform from scratch.
• Long-term potential: future features, optimization, and spin-offs.


To Apply:
Please send:
1. A brief intro about your experience with AI/web apps.
2. Links to past projects (especially if they involve in-browser ML or Firebase).
3. A quick analysis of how you would build this product out (tech stack, model handling, ad integration, scaling).

I look forward to reading your application. Thank you!
