<p>Most in the software development industry will agree that for years, testing was treated as the last task in the SDLC. This was expensive to the company as teams invested time, effort, and money into gathering requirements, building features, pushing for delivery timelines, and only at the end was QA allowed to test the product. ...</p>

<p>In software development, the terms system design and software architecture are often used interchangeably. However, while they are closely related, they are actually different. They serve different purposes and focus on different aspects of software systems. System design deals with the specifics of how the system will be implemented, including components, interfaces, and technologies. Software ...</p>

<p>Large Language Models (LLMs) have drastically changed the way software systems process information, produce responses, and aid humans in making decisions. But for all their wizardry at reasoning and natural language, LLMs have a fundamental limitation; They do not intrinsically &#8220;understand&#8221; your data. All those techniques, including RAG, Agentic-RAG, and Model Context Protocol, are there ...</p>

<p>API has been the foundation of modern technical infrastructures for decades. They provided modular architectures, microservices, SaaS ecosystems, and cloud-native platforms. Almost every integration tale in software engineering has rightly been an API tale. The advent of Large Language Models (LLMs) and AI agents has, however, disrupted entirely how software systems are consumed and orchestrated. ...</p>
