I have an AI-driven website-builder SaaS that needs a senior developer to get it production-ready and keep it running smoothly. The core stack is JavaScript/Node.js on both the server and client, so deep experience with modern Node, Express, React (or similar) and a solid grasp of ES-next patterns are essential. Your first task is to install the existing codebase on my cloud environment, resolve any dependency or build issues, and make sure the drag-and-drop builder, automated SEO routines, and library of customizable templates all compile and perform as intended. Once the platform is live, I need reliable payment-gateway integration (Stripe is the immediate priority, with the code structured so additional gateways can be added later). After the installation and debugging phase, I want ongoing support: patch new bugs, optimise performance, add incremental features, and keep the third-party libraries up to date so the SaaS stays secure and competitive. Deliverables • Clean installation with zero critical errors • Fully functioning drag-and-drop editor, SEO automation, and template system • Stripe (or equivalent) payments flowing end-to-end in test and live modes • Concise deployment notes so I can replicate the setup • Monthly code-health review and hot-fix response within agreed SLA If you have shipped production SaaS in Node.js, value clean, test-covered code, and are open to a long-term collaboration, I would like to start right away.

Your builder is already past the “just code it” stage — the real need now is getting the existing Node/React app stable in production, with the editor, SEO routines, and template system working together without build or runtime surprises. The first step I’d take is to get the code running cleanly on your cloud environment, isolate dependency/version conflicts, and then harden the payment flow so Stripe works properly now while keeping the gateway layer extendable later. I’ve worked on JS-based web apps where the challenge was not only shipping features, but making an existing codebase deployable, maintainable, and safe to keep evolving. That includes debugging broken builds, resolving package conflicts, improving API/frontend coordination, and structuring integrations so future additions do not create technical debt. I can also provide concise deployment notes as the environment is finalized. - Which cloud environment are you deploying on right now? - Is Stripe partially implemented already, or would this be integrated fresh? - Do you already have a bug list/test flow for the builder and template engine, or should that be part of the initial audit?

Hi, I can help get your AI website-builder SaaS production-ready and provide reliable long-term maintenance. I’ll handle: - Cloud installation, dependency fixes & build troubleshooting - Node.js/Express + React codebase optimization - Drag-and-drop builder, SEO automation & template system validation - Stripe integration with a scalable gateway architecture - Security, performance & third-party dependency updates - Testing and critical bug fixing - Deployment documentation and production handover - Ongoing monthly code-health reviews and SLA-based support I’ll first audit the existing codebase and deployment environment, identify blockers, and then work through them systematically without disrupting existing functionality. Quick questions: 1. Which cloud provider is currently being used? 2. Is the existing codebase already in Git/GitHub? 3. Do you have Stripe test/live accounts ready? 4. What response time would you expect for critical production issues? I’m available to start immediately and would be interested in a long-term development and maintenance partnership.

What stands out here is that you do not need a basic developer to “install and hope” — you need someone who can take an existing AI website-builder codebase, make it production-ready, and keep it healthy over time. I’d begin with environment setup and dependency cleanup, then verify the drag-and-drop flow, SEO automation, templates, and payment architecture as one connected system rather than treating them as separate fixes. A SaaS like this usually breaks at the edges: package mismatches, cloud config differences, weak error handling, and integrations that work in test mode but not under real usage. I’ve handled Node/Express and React-based debugging, deployment stabilization, and ongoing enhancement work where clean structure and long-term maintainability mattered just as much as the immediate fix. Deployment notes and a practical maintenance rhythm can be built into the process from the start. - Which parts are currently unstable: installation, build pipeline, runtime behavior, or all three? - Are you using plain React, or another frontend layer/framework on top of it? - For ongoing support, do you already have an expected SLA window in mind for hot-fixes?

Hey there, The fastest way to get this SaaS moving is to stabilize the existing codebase and deployment first, so the builder, SEO automation, and template system are working properly before adding Stripe and new complexity. For this SaaS, I’d treat the existing codebase and deployment as the first priority rather than jumping straight into new features. Getting the builder, SEO automation, and template system running correctly in the target cloud environment will make it much easier to identify and resolve the actual dependency and build issues before Stripe is introduced. I work with JavaScript/Node.js and can handle the project across the application stack, including debugging existing code, API development, and production issues. For Stripe, I’d also keep the payment layer modular enough that adding another gateway later won’t require reworking the core billing flow. Do you already have the cloud environment provisioned, or should the deployment setup be included in the initial work?
