Sazyo - B2B SaaS for nutrition professionals

A B2B SaaS I designed and built end to end for nutrition professionals, currently in pilot phase with real practitioners.

Stack and scope: Angular frontend, Django backend, PostgreSQL, Stripe self-service billing with a 30-day trial and server-side read-only downgrade, multi-practitioner studios, automated and monitored backups, CI and error tracking with PII (Personally Identifiable Information) filtering.

On a profile focused on eCommerce-ERP integrations, this is the full-stack proof: the same engineering standards I apply to integrations, applied to a complete product.
