Enhance Customer Retention SaaS Platform

@kamran2012

I can help with this, I will review the existing codebase and documentation, complete the Tranzila payment integration, refine the admin panel, and stabilize the WhatsApp automation workflows — bringing the platform to production-ready quality. For the payment layer, I will add webhook-based confirmation handling so subscription status updates reliably even if a user closes the browser mid-checkout — a common edge case with Tranzila. Questions: 1) What is the current tech stack — Node.js, React, or something else? 2) Is the WhatsApp integration using the official Cloud API or a third-party provider? Looking forward to potentially working together. Thanks, Kamran

Hi, Your project is particularly interesting because the platform is already in an advanced stage and the priority is not rebuilding from scratch, but efficiently taking ownership of an existing SaaS product, understanding the architecture, and bringing it to production-ready quality. I have experience working with existing codebases, reviewing technical documentation, debugging complex systems, integrating third-party APIs, payment gateways, CRM workflows, and automation platforms. I understand the challenges involved when inheriting a project from another developer and can quickly assess the architecture, identify bottlenecks, and continue development without disrupting existing functionality. For this project, I would begin with a structured audit of the codebase, documentation, bug reports, automation workflows, and Tranzila integration status. From there, I can prioritize payment completion, workflow stabilization, admin panel enhancements, UI/UX improvements, and bug resolution while maintaining system stability. I am comfortable taking ownership, working independently, documenting changes, and providing ongoing support after launch. Best, Justin

Hi there, We’ve developed multiple customer-facing products that use WhatsApp Business APIs for automated messaging and customer engagement. We’ve also integrated various payment gateways, including Stripe and PayPal, and have extensive experience with subscription-based billing models. As a team of full-stack developers, we can assign specialists based on the specific task at hand. For example, we can have a front-end expert work on UI improvements while a back-end developer focuses on server-side optimizations, ensuring you get the best of both worlds. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m eager to learn more about your exciting project. Best, Adil

Hello, Yokneam Ilit — clinic retention SaaS, previous dev gone, codebase nearly complete. Taking over an existing project is a different skill than building from scratch, and the first thing I'd do is read the full documentation before touching a single file. Tranzila integration, subscription plan management, WhatsApp automation workflow fixes, bug list cleared, and admin panel tightened — all deliverable in sequence with clear progress updates so you always know where things stand. I've taken over mid-stage SaaS builds before; the risk is always undocumented edge cases the previous dev left behind, which is why I'd do a full codebase audit in the first two days before estimating the remaining scope precisely. Looking forward to working with you. Mateo
