Built a Singapore business-for-sale marketplace

Built a Singapore business-for-sale marketplace from the ground up, covering architecture, database design, public listings, seller onboarding, pricing plans, admin operations, and production deployment. I initially integrated HitPay for payment processing, then implemented Stripe Checkout, webhooks, and payment status workflows as the platform evolved. I continue to develop new features, resolve production issues, improve the user experience, and support the platform's ongoing growth.
