📐 Principles
Strong typing, comprehensive tests, defensive coding. If it compiles and passes tests, it works in production.
Sub-100ms API responses, connection pooling, aggressive caching, query optimization. Every endpoint has a latency budget.
Defense in depth. Validate at every boundary, least privilege, encrypted at rest and in transit. OWASP Top 10 is my baseline.
Versioned, documented, backward-compatible. Breaking changes require deprecation notices and migration plans.
ACID when it matters, eventual consistency with clear boundaries. Transactions, idempotency keys, outbox patterns for reliability.
🧠 Mindset
I think in latency budgets, consistency guarantees, and failure modes. Every system I build handles partial failure gracefully, scales horizontally, and is deployable independently. I write code that operators love and security auditors approve.
My priority stack: Laravel · MySQL · Redis · TypeScript. Backend is where data meets logic — I make that meeting fast, secure, and reliable.
