Implements a generic 2D collision resolution algorithm for positioning resource cards on a canvas. Exports `resolveCanvasNodeLayout` and `resolveCanvasNodePosition` functions that handle overlapping rectangles by shifting nodes to the nearest non-colliding position. The algorithm is self-contained, uses only basic geometry, and can be extracted into any project requiring automatic layout of draggable elements (e.g., diagram editors, dashboards). Demonstrates non-obvious skill in spatial reasoning and efficient collision resolution.

Provides a unified `runOptimisticUpdate` function that encapsulates the optimistic update lifecycle: apply a temporary state change, execute an async operation, and either commit or rollback with a notification callback. The pattern is framework-agnostic (no React or Vue dependency) and can be reused in any JavaScript project to reduce UI latency. Includes TypeScript generics for type safety and supports custom rollback logic.

Compares two application configuration snapshots (before and after a change) and produces a structured diff indicating which fields changed and whether a rebuild or redeploy is required. The diff is used to warn users about pending changes and to decide if a full deployment is necessary. The class is self-contained, uses a `ConfigurationDiffer` helper, and can be extracted to any system that needs to track configuration drift and trigger actions based on changes.

Parses Docker image references into structured components: registry URL, image name, tag, and SHA256 digest. Handles edge cases like implicit Docker Hub references, port-based registry URLs, and digest-only references. The parser is stateless, well-tested, and can be reused in any PHP project that needs to validate or decompose Docker image strings. Demonstrates careful handling of the Docker image specification.

A Laravel validation rule that accepts either a valid cloud-config YAML document or a plain bash script. It attempts to parse the input as YAML and checks for required cloud-init keys (`runcmd`, `packages`, `users`, etc.) or falls back to treating it as a shell script. The rule is self-contained, uses Symfony YAML parser, and can be extracted to any PHP project needing cloud-init validation. Demonstrates practical handling of multi-format input.

A Laravel Eloquent trait that adds a `noindex` flag to domain models (Application, ServiceApplication) and provides a `scopeWithNoindexDomains` scope. It normalizes the `noindex` attribute by checking both the model's own flag and a global instance setting. The trait is small, focused, and can be reused in any Laravel project that needs to manage per-domain SEO indexing preferences with a fallback to global defaults.
