Raw WebSockets can turn into an unmaintainable mess unless you define a tiny protocol up front. I keep messages typed (even if it’s ‘JSON with a type field’) and I implement topic subscriptions so clients opt into exactly what they need. I track subsc

Loading everything on initial page render slows perceived performance. Lazy-loaded Turbo Frames defer expensive content until it's needed, keeping initial page loads fast. Setting loading='lazy' with a src attribute tells Turbo to fetch content when t

Nested writes should be transactional: either everything is created or nothing is. Rails does this well when you keep validations coherent and avoid side effects in callbacks.

Turbo supports data-turbo-confirm, but sometimes you want a stronger confirmation step (type-to-confirm, extra context, multi-step). Stimulus lets you implement consistent confirmations without sprinkling JS across views.

Optimized Docker images reduce build time, storage, and attack surface. Alpine-based images start at 5MB versus 100MB+ for Debian. Multi-stage builds separate build tools from runtime—final image contains only production artifacts. Layer ordering matt

RSpec provides powerful testing tools for behavior-driven development. Shared examples reduce duplication across similar specs—I extract common behavior into reusable examples. Contexts organize tests by different scenarios. Let blocks lazily evaluate

CSS Grid provides two-dimensional layout control for rows and columns simultaneously. I use display: grid to create grid containers. The grid-template-columns and grid-template-rows properties define track sizes. The fr unit distributes available spac

EncryptedSharedPreferences secures simple key-value data using Android Keystore. I create instances with EncryptedSharedPreferences.create() specifying encryption schemes. The master key uses MasterKeys or MasterKey.Builder for automatic key generatio

Java Records (JDK 14+) provide concise syntax for immutable data carriers. Records automatically generate constructor, getters, equals, hashCode, and toString. I use records for DTOs, value objects, and API responses. Records are final and all fields

Drag and drop UIs feel natural for reordering lists or organizing content. The dnd-kit library provides accessible, performant drag and drop with full keyboard support. I use DndContext to wrap draggable areas, useSortable for sortable list items, and

GitLab CI/CD uses .gitlab-ci.yml for pipeline configuration. Pipelines consist of stages that run sequentially. Jobs within the same stage run in parallel. The image key sets the Docker image for each job. variables define global or job-level environm

Glide efficiently loads and caches images from network, disk, or resources. I use Glide.with(context).load(url).into(imageView) for basic loading. Transformations apply effects—centerCrop(), circleCrop(), RoundedCorners(). Placeholders show during loa
