Full stack SAAS developer to finish existing app- stripe, Cloudflare, admin dashboard

Full-Stack SaaS Developer to Finish Existing App — Stripe, Cloudflare & Admin Dashboard I am looking for an experienced full-stack developer to complete and prepare an existing web application for commercial launch. The core application has already been substantially built. I am not looking to rebuild the product from scratch. I need someone who can complete the remaining commercial infrastructure, test the system, and prepare it for reliable public use. Primary Work 1. Payment and Customer Access Complete or validate: * Stripe integration; * one-time and subscription payments; * customer entitlement after payment; * usage limits and tracking; * payment/subscription synchronization; * refunds and cancellations where applicable; and * prevention of duplicate or unauthorized access. 2. Owner/Admin Dashboard Create or complete a secure owner dashboard where I can: * view customers, payments, subscriptions, and usage; * see remaining customer allowances; * identify failed transactions or customer issues; * review system activity and relevant errors; * manually adjust customer access when appropriate; * monitor API or product usage; and * make routine business and product updates myself without needing a developer. The dashboard does not need to be visually elaborate. Reliability, usability, and practical control are more important. 3. Launch Readiness Review the existing application and determine whether it is ready for real customers. Existing Technology The application currently uses or may use: * Cloudflare Workers; * Cloudflare D1; * Stripe; * transactional email; * AI/LLM APIs. Experience with Cloudflare Workers and D1 is highly desirable. When Applying Please answer: 1. Have you taken over and completed an application originally built by another developer? Please describe one example. 2. What experience do you have with Stripe payments, subscriptions, webhooks, and customer entitlement/access logic? 3. Have you built an internal owner/admin dashboard for a SaaS product? What information and controls did it include? 4. What experience do you have with Cloudflare Workers and Cloudflare D1? Please include examples of relevant applications you have built or completed. Please do not send a generic agency proposal. I am specifically interested in hearing from the developer who would personally review and work on the application.
