STRICT
PROTOCOL.
The universal engineering standards governing every system in the DevStacks ecosystem. From layered architecture to zero-trust security.
Layered Architecture
API/Controller, Service/Business, and Repository/Data layers for modularity and testability. Decoupled logic using DTOs and Domain Models.
Security & Zero Trust
Strict input validation, RBAC identity management, and transit/at-rest encryption. Zero hardcoded secrets with managed rotation.
Data Integrity
Versioned schema migrations, transactional business operations, and strict validation at both application and database constraints.
Efficiency
Avoidance of N+1 problems, multi-level caching strategies, and stateless execution for seamless horizontal scaling.
Testing Infrastructure
70/20/10 testing pyramid balancing Unit, Integration, and E2E tests. Contract testing for distributed systems.
Resilience
Full observability via Logging, Metrics, and Tracing. Circuit breakers, bulkheads, and exponential backoff retry patterns.
Proximity Docs
Documentation-as-Code. Local Module READMEs explaining 'the why' and business rationale close to implementation.
API Design
Standardized JSON envelopes, semantic HTTP verbs/codes, and robust URI versioning with sunset policies.
Compliance is
Non-Negotiable.
Every system originating from DevStacks Labs follows these standards to ensure the builds we scale are not just functional, but enduring.
