I built and deployed two live serverless products on Cloudflare Workers from a single codebase: Alto Reviews, a reviews-automation SaaS, and Alto Home Improvements, a two-sided services marketplace.
For Alto Reviews, I integrated the Meta WhatsApp Business Cloud API, automated onboarding and review-tracking conversations, and PayFast card and Instant EFT payments. I also replaced GoHighLevel with self-built software and reworked checkout pricing using production data to improve payment conversion.
I extended the same engine into a multi-tenant marketplace with two WhatsApp brands, isolated environment configuration, pay-as-you-go credits, automated refunds, reconciliation, and supplier onboarding tools.
I own delivery end to end, from responsive landing pages and conversion-focused flows to webhooks, serverless backend architecture, versioned deployments, monitoring, and end-to-end testing.
