Soul Global 2.0
A full architectural rewrite of Soul Global — from a React + REST monolith to Next.js 16 Server Components with durable workflows.
Version 1 proved the product but accumulated client-side complexity and a brittle order model. Version 2 is a ground-up rewrite on a server-component-first architecture, with Inngest workflows and a complete Brazilian import tax engine. The hard part was migrating live production data while v1 kept serving paying customers.

✶ Live data migration (11-step → 7-step)
Migrated the legacy schema to a simpler order model while preserving every historical order, contract, and payment. Ran in shadow mode against production for weeks, comparing v1 vs v2 row-by-row before a reversible cutover.
✶ Client-fetching → React Server Components
Re-architected to Next.js 16 Server Components by default, dropping initial load weight and reworking auth and caching that were core to v1's client-side SWR model.
✶ Durable workflows with Inngest
Replaced manual state machines and fragile cron jobs with Inngest workflows — order progression, payment reconciliation, and operator queues survive crashes, retries, and 3rd-party outages.
✶ Brazilian import tax engine
Full CIF → II → IPI → PIS/COFINS → ICMS cascade with multi-currency handling, computed with Decimal.js so rounding never drifts.
