GitOps

Cross-platform development is the practice of building applications that run on multiple operating systems (iOS, Android, web, desktop) from a single codebase. Frameworks like React Native, Flutter, and Kotlin Multiplatform each take different approaches — from shared UI rendering to shared business logic with native UI. The key trade-off is between code reuse efficiency and the ability to deliver platform-native experiences that feel right on each device.

A message queue is a middleware component that enables asynchronous communication between services by temporarily storing messages until the receiving service is ready to process them. Popular implementations include RabbitMQ, Amazon SQS, and Redis Streams. Message queues are essential for automation workflows because they decouple producers from consumers, handle traffic spikes through buffering, and ensure reliable delivery even when downstream services are temporarily unavailable.

Terraform is an open-source Infrastructure as Code tool by HashiCorp that lets you define cloud and on-premise resources in declarative configuration files using HCL (HashiCorp Configuration Language). It builds a dependency graph of resources and applies changes incrementally, showing a plan before making any modifications. Terraform supports hundreds of providers including AWS, Azure, GCP, and Cloudflare, making it a de facto standard for multi-cloud infrastructure automation.

Infinite scroll is a UX pattern where new content loads automatically as the user scrolls toward the bottom of the page, eliminating traditional pagination. It's commonly used in social media feeds and content discovery interfaces. While it increases engagement and feels seamless, it can hurt performance without virtualization and makes it difficult for users to reach footer content or bookmark specific positions.

Flexbox (Flexible Box Layout) is a one-dimensional CSS layout model designed for distributing space and aligning items within a container along a single axis — either horizontal or vertical. It excels at handling dynamic content sizes, centering elements, and creating flexible navigation bars, card rows, and form layouts. Properties like `justify-content`, `align-items`, and `flex-grow` give you fine-grained control over how items share available space.

Idempotency means that performing the same operation multiple times produces the same result as performing it once. This property is critical in automation and distributed systems where network failures or retries may cause a request to be sent more than once. APIs, payment processing, and deployment scripts should be designed to be idempotent so that retries are safe and don't create duplicate side effects.
