We are building a B2B SaaS platform that provides developers with API access to our proprietary AI backend. The core AI processing engine is already built and containerized. We are looking for an experienced Full-Stack Developer to deploy an open-source API management gateway (e.g., New API or One API) alongside our engine, and build a custom [login to view URL] web storefront where users can register, top up their API credits, and manage their API keys. Core Responsibilities: Frontend Dashboard ([login to view URL] / Tailwind): User authentication (Email/Password & Google OAuth). A dashboard displaying the user's current credit balance and API usage charts. A button to generate, view, and revoke personal API keys. Payments & Billing (Stripe): Implement a "Prepaid Wallet" system. Users select an amount (e.g., $10, $50) to top up their account via Stripe Checkout. Listen to Stripe Webhooks to accurately update the user's quota balance in the API Gateway upon successful payment. Gateway Integration & DevOps: Deploy an open-source API management gateway via Docker on our Linux VPS. Write the backend logic so the [login to view URL] site syncs user profiles and token balances with the Gateway via REST API. Deploy the web app securely behind a reverse proxy (Nginx/Caddy) with SSL, ensuring our internal backend ports are not exposed to the public internet. Required Tech Stack: [login to view URL] (React) & Tailwind CSS Node.js / TypeScript PostgreSQL Stripe API (Specifically Checkout & Webhooks) Docker & basic Linux networking

Hi, You're building an AI-powered API platform for developers—that means rock-solid backend architecture and seamless integrations matter most. Quick question: are you prioritizing API performance and rate-limiting from day one, or scaling that later? We've shipped similar Node/Next stacks. Let's talk details. Best Regards, Hasan

Hi there, Regarding your B2B SaaS platform, I've noticed that deploying the API management gateway efficiently can often present bottlenecks, especially with syncing user profiles and token balances. I ensure seamless integration by optimizing REST API interactions and deliver a secure, efficient deployment. In a past project, I integrated a similar API gateway for a SaaS platform, resulting in a 30% improvement in API response times. I include 30 days of post-deployment bug-fixing to ensure smooth operation. Have you considered which open-source API management gateway best aligns with your current architecture? Let's discuss how I can help streamline your deployment.
