React Developer Needed for Upsell, Emails & Subscription Management

@asifalimzd

Hi there, I’m an experienced React developer with hands‑on expertise using Supabase as a backend. I can help refine your skincare store by: 1. Upsell integration – adding a post‑checkout upsell flow that captures additional product sales seamlessly. 2. Webhook fix – debugging and correcting your current webhook error so order events trigger reliably. 3. Confirmation emails – setting up automatic transactional emails after successful checkout, using Supabase functions or a lightweight email service. 4. Subscription management – enabling manual cancellation directly from your merchant dashboard with proper backend logic. Approach: I’ll start with a quick audit of your current checkout and Supabase functions, then implement fixes and enhancements step‑by‑step, testing each feature across desktop and mobile. Please visit my profile for examples of past work. Kindly send me a message to discuss further. Thanks and regards, — Asif Ali Zaman

@royalwebraisers

Hi, As per my understanding: your live React store using Supabase needs a post-checkout upsell flow, webhook error resolution, automated confirmation emails, and merchant-level subscription cancellation. I work across React frontends and Supabase-backed systems with structured debugging and clean logic. I will share my portfolio on your first message. Implementation approach: • Implement validated post-checkout upsell tied to payment session • Trace and fix webhook via logs and endpoint verification • Configure automated email trigger on successful transaction • Add secure admin-based subscription cancellation control Queries: • Which payment gateway manages subscriptions? Estimated timeline: 5–7 days. Budget: $350–$450. I am sure about the delivery after our first meeting. Kind regards

Hi client, I appreciate you sharing the details for your e-commerce project. I'm Nikhil Chandra Roy, a dedicated React developer with extensive experience, and I'm confident I can help improve and optimize your live skincare website. **React + Supabase Experience:** Yes, I possess strong expertise in building dynamic frontend applications with React.js and integrating them seamlessly with Supabase for robust database management, authentication, and real-time features. My backend skills also include Node.js, which is highly effective for extending Supabase functionalities via Edge Functions. **My Approach:** 1. **Upsell Integration:** I will implement a responsive upsell prompt (e.g., a modal or section) using React after successful checkout. This involves integrating with your product data and securely updating Supabase records upon user acceptance. 2. **Webhook Error Fix:** I'll meticulously diagnose the webhook error using available logs (Supabase, payment gateway), identify the root cause, and implement a durable solution, followed by thorough testing to ensure stability. 3. **Confirmation Email:** I will set up an automated email system, likely leveraging Supabase Edge Functions or a small Node.js service, to trigger a personalized confirmation email immediately after every successful checkout, utilizing a professional template. Regard's Nikhil.

@sasaprogramer21

Yes, I have experience building and fixing live React sites backed by Supabase, including checkout flows, webhook handling, and post purchase automations. How I would approach this First I would reproduce the webhook error in logs and verify the full checkout to Supabase update path. I would confirm signature verification, idempotency, and event ordering so the same checkout cannot create duplicates or fail silently. Next I would add the post checkout upsell as a clean step that does not risk payment or subscription state, then persist acceptance or decline in Supabase for analytics. Then I would implement automatic confirmation emails on successful checkout using a server side trigger from the verified webhook event, not from the client, so it is reliable. Finally I would add manual subscription cancellation inside your merchant dashboard through a secure admin only action that calls your payment provider and updates Supabase state. Thanks.
