Leadership takeaway
This week (23/02 - 01/03) the team landed the full POS sale-to-payment flow with real-time encrypted WebSocket payments, and re-platformed two foundations - a dedicated pricing/promotion package carved out of commerce and a Debezium/Kafka CDC search pipeline replacing the old Sequin path.
- POS Sale Flow - Completed the end-to-end cart-to-payment lifecycle across phone and web, including pull-to-refresh and QR-scanner fixes on device builds.
- Real-time Payments - Replaced QR-status polling with a WebSocket channel secured by ECDH + AES-256-GCM end-to-end encryption, plus a native NFC plugin and signal client.
- Pricing & Promotions - Extracted pricing out of commerce into its own package with promotion CRUD, time-based rules, and pricing wired into the sale checkout step.
- Search Re-platform - Migrated change-data-capture from Sequin to Debezium on Kafka, with product-name/description indexing and a more reliable consumer (explicit commits, type-safe producers).
- Identity & Authorization - Moved user-mapping to a policy-based model, added customer CRUD, and reworked JWS auth and role identifiers.
- Admin Foundations - Introduced a shared design system and extracted the auth provider into the admin UI kit for cross-app reuse.
