Full-Stack Developer Needed for Technical Review & Potential Ongoing Support

I’m looking for an experienced full-stack developer to review an existing live subscription-based web application and potentially provide ongoing technical support. The application is already built and in active development. I am not looking for a rebuild at this time. My immediate goal is to have an independent developer review the current setup, understand the architecture, and determine how easily the application could be maintained or supported by another developer if needed. The platform includes user accounts, subscription/payment functionality, third-party API integrations, cloud hosting, and an image/rendering workflow. I’m looking for someone with experience in: * Full-stack web application development * Existing production codebases * Cloud-hosted applications * Stripe subscriptions/payment flows * Third-party API integrations * Troubleshooting and performance optimization * Security and reliability reviews * Taking over or supporting applications originally built by another developer Strong communication is extremely important. I’m looking for someone who is responsive, dependable, and able to explain technical issues and recommendations in clear, non-technical language. Initial scope: Review the existing application and provide an assessment of: * Overall codebase quality and maintainability * Infrastructure and deployment setup * Any obvious technical or security concerns * Ease of ongoing maintenance * What would be required for another developer to provide backup or long-term support This may lead to ongoing development or maintenance work if it is a good fit. Please include: * Your experience maintaining or inheriting existing applications * Examples of similar production projects * Your experience with subscriptions/payments and API integrations * Your typical approach when taking over an unfamiliar codebase * Your availability for ongoing support if needed Please do not propose rebuilding the application from scratch. I am specifically looking for an assessment and potential support of the existing platform.
