Subscription SaaS and DTC membership companies losing 5–10% of MRR each month to involuntary failed credit cards and preventable voluntary cancellations frequently search to hire a freelance SaaS retention, smart dunning & churn-prediction programmer. I am Aldian Fazrihady, a Senior Freelance Full Stack Developer and Data/AI Engineer.
Core MRR Recovery & Retention Engineering Capabilities
- Dynamic Cancellation Save Flows: Building interactive exit-survey modals that dynamically offer pause-subscription windows, downgrade tiers, or targeted 1-click Stripe coupon discounts based on the user's cancellation reason and LTV cohort.
- Involuntary Churn & Smart Dunning Automation: Handling `invoice.payment_failed` webhooks, card-updater notifications, in-app payment-update banners, and multi-channel SMS/email frictionless payment recovery links.
- Behavioral Churn-Risk Scoring: Training LightGBM / logistic survival models on product usage telemetry (login frequency drop, unused seats, support ticket sentiment) to alert Customer Success managers 30 days before renewal.
Frequently Asked Questions
How much MRR can an intelligent cancellation and dunning flow recover?
