Real production systems — most from Fenix Commerce's event-driven platform (10+ modules, 40+ active retailers, 90+ at peak), plus earlier architecture work — with the constraints, the decisions, and the scale behind each.

Fenix Intelligent Delivery Engine (EDD)
The engine that answers 'when will it arrive?' on live retail traffic, scaled from 44M to 416M+ requests a year, under 150ms.

Order & Fulfillment Pipeline
A high-volume enterprise pilot exposed silent data loss and Shopify auto-deregistering our webhook. Ingestion was rebuilt event-driven on Kafka to fix both, for good.

Built and shipped in 2 months to win an enterprise account we'd chased for 4 years. It expanded into a multi-product, multi-site customer.

Notifications Platform
The tracking page was a pull model: a shopper had to go check it. Competitors were pushing status updates instead, so this platform closed that gap from the ground up.

Multi-Tenant Data & Read-Model Architecture
Strict per-tenant isolation, volume-adaptive indices, and one real-time summary read model that powers the tracking page, notifications, returns, dashboards, and ML training.

Machine-Learned Delivery Predictions & Four-Way Validation
Replaced static carrier SLA tables with proprietary ML models, then built the validation loop that proves, shipment by shipment, how right they are.

Loyalty & Conversion Engine
Two configuration-driven coupon engines: one repairs trust after a late delivery, the other recovers an abandoned cart. Same rules pattern, two different problems.

Platform Modernization
JDK 21 Migration & Virtual Threads
One platform-wide migration removed a thread-cost ceiling that touched order processing, carrier tracking, and every tenant's notifications at once.

After the contract is signed, I scope, build, and own the onboarding, then carry the pager. That trust is what turns single-product accounts into multi-product ones.
