Architectural Principles & Standards
Core engineering decisions governing every distributed system and application I build.
End-to-end TypeScript interfaces and Zod runtime schema validation eliminate whole classes of production runtime exceptions before deployment.
Ship zero client-side JavaScript by default via Astro 7 Islands, serving pre-rendered HTML from 300+ Cloudflare edge PoPs in under 25ms.
Distributed Redis Redlock mutexes and PostgreSQL SELECT FOR UPDATE locks guarantee zero double-bookings or race conditions under high concurrent loads.
Transactional Outbox pattern combined with Change Data Capture (CDC) ensures database state and event-stream brokers remain perfectly synchronized.
