About this gig
Are you looking to scale your SaaS platform, multi-vendor marketplace, or CRM by enabling seamless payment workflows?
As an expert web and mobile application developer, I specialize in architecting secure, scalable, and legally compliant payment systems. Whether you need to charge users a recurring subscription fee or dynamically split funds between customers and individual business merchant accounts (like a custom CRM or food delivery platform), I have you covered.
I focus heavily on Stripe Connect (Standard, Express, and Custom architectures) to build robust marketplace ecosystems that bypass platform legal liabilities and automatically route funds directly to your vendors' bank accounts.
What I Can Build For You:
- SaaS Subscription Models: Automated recurring billing tiers, customer portals, and usage-based invoicing using Stripe Billing.
- Multi-Vendor Marketplaces: Dynamic merchant onboarding via Stripe Connect where businesses register their own bank accounts securely.
- Split Payments & Escrow: Custom payout logic allowing you to take an automatic platform commission fee on transactions.
- Real-Time Sync: Enterprise-grade webhook handling (payment_intent.succeeded) to
