DynamoDB is great at fast single-item reads and writes. The hard part shows up when one business action needs multiple items to change together. Examples: * Decrease stock and create an order * Debit one wallet and credit another * Book a seat and mark it unavailable If you do those as separate
Maybe you just lost your job. Maybe you’re stuck somewhere that doesn’t make you happy anymore. Or maybe you’re simply ready for a new beginning. Whatever the reason — this moment is not the end. It’s the start of your next chapter. Finding a new job can
You’ve done it. You’ve built and deployed a slick, scalable application on AWS Lambda. It’s the serverless dream! But then you notice it… a frustrating, unpredictable delay the first time a user hits an endpoint. Sometimes, it's just… slow. If this sounds familiar, you'
Finding a job isn’t just about luck — it’s about clarity, direction, and preparation. Whether you’re in tech, marketing, healthcare, education, finance, or any other field, having a solid plan will help you focus your energy on opportunities that truly fit you. 1. Identify What You Want Before
In test automation, maintaining and reusing state between test cases is essential for creating efficient, end-to-end workflows. When writing Cypress tests that interact with APIs, it's common to receive dynamic data from a response—such as an ID, token, or reference number—that you'll need to
Cypress is a powerful tool for end-to-end testing, but sometimes you need to halt execution immediately when a critical failure occurs. Enter Cypress.stop(). This command stops all test execution, ensuring you avoid cascading failures or wasted resources when a prerequisite fails. Let’s explore how to use it effectively.
When building serverless applications, you may encounter scenarios requiring AWS Lambda functions to be invoked across different AWS accounts. Cross-account Lambda invocation can be a powerful tool for organizations that manage multiple AWS accounts and want to facilitate secure and efficient inter-account communication. This article explores how to configure cross-account
In modern application development, invoking AWS Lambda functions is essential for various back-end tasks, from simple requests to complex data processing. While tools like Cypress are widely used for front-end testing, it can also be extended to test the integration of back-end services like AWS Lambda. In this article, I’
In the complex world of software development, ensuring quality is crucial. QA professionals rely on a trio of testing techniques: smoke, sanity, and regression. While these terms might sound similar, each serves a unique purpose in the software development lifecycle. Let’s explore these essential quality assurance methods. Smoke Testing:
In an age where technology is rapidly advancing, it's easy to overlook the value of manual testing. Yet, as software development evolves, the role of manual testers remains crucial. Often seen as a lesser discipline, manual testing is, in reality, the backbone of quality assurance (QA) that can
In today's world, ensuring data security is critical for any application. AWS Key Management Service (KMS) provides a simple way to encrypt and decrypt sensitive data. In this post, we'll cover how to use AWS KMS for encrypting and decrypting data, including steps to create a
In the agile era, where iterative development and continuous feedback are paramount, the traditional approach of waiting until the testing phase to uncover and fix software errors is increasingly seen as inefficient. Agile methodologies emphasize early and frequent testing, collaboration, and incremental improvements. Here's why waiting until testing
