Cursor Automations, MCP, and API Integrations: How AI-Powered Workflows Are Reshaping Modern Development
In late 2025, most developers were still using AI coding assistants as glorified autocomplete engines: press Tab, accept a suggestion, and move on. By mid-2026, the same tools are reviewing pull requests, triaging incidents from PagerDuty alerts, posting summaries to Slack, and assigning reviewers based on time zones, all [...]
The Modern Developer: AI, Cloud, and What Comes Next
For the longest time, the standard advice for entering the technology industry was simple: learn to code. But as AI in software development becomes more common, knowing how to write code is no longer the whole story. At first it's like this: learn Python, JavaScript, Java, or another programming [...]
Agentic AI on AWS: From Terraform Modules to the Model Context Protocol
Most teams deploying AI on AWS were still running the same playbook: take a foundation model, wire up a retrieval layer, wrap it in an API Gateway endpoint, and call it a chatbot. By mid-2026, the same teams are deploying autonomous agents that reason through multi-step workflows, authenticate against [...]

Terraform vs AWS CloudFormation: Which Is Better for Building Serverless Applications?

Serverless applications feel effortless — until you try to scale. You might start with a single AWS Lambda function. Soon, you add API Gateway endpoints, DynamoDB tables, S3 triggers, SNS notifications, and maybe Step Functions to orchestrate your workflow. Before long, your AWS console looks like a maze, and manual management becomes nearly impossible. Serverless doesn’t mean there are no servers. It means you don’t manage them. AWS handles provisioning, scaling, and maintenance while [...]

Data Preprocessing Guide for Beginners in ML

Before machine learning (ML) models can generate predictions or insights, the raw data must first be cleaned, organized, and transformed into a suitable format for the model. This process is known as data preprocessing. It is the foundation of every successful ML project. It ensures that the model learns from high-quality, consistent, and well-structured input rather than noisy, incomplete, or biased information. In this hands-on guide, we’ll walk through how to transform a raw [...]

Amazon Bedrock + Promptfoo: Rethinking LLM Evaluation Methods

I discovered something embarrasing about my LLM development workflow last month. After spending hours crafting what I thought was the perfect prompt for a customer service chatbot on Amazon Bedrock, I deployed it and called it done. My validation process? I asked it five questions, nodded approvingly at the responses, and moved on. Sound familiar? This "vibe-based prompting" approach worked fine until the chatbot confidently told a user that our fictional company offers "24/7 [...]

Tech Burnout: Is It Really Inevitable?

What if the dream job, the one you've always been dreaming of and manifesting ever since, is quietly draining the life out of you? This exhaustion is a known feeling in the tech industry, where the relentless pressure forces professionals and students to push until they hit a wall. This struggle is intensified in cultures that value sheer willpower and "diskarte" (resourcefulness), where admitting this profound fatigue feels like a personal, silent failure. We've [...]

Rise of Microservices in Modern Apps: From One Block to Many

Have you ever thought about the pain of fixing just one small piece of a massive software system without accidentally breaking everything else? Honestly, most of the time, that is almost impossible. That challenge led to the rise of microservices in modern apps. It marked a shift from old monolithic architectures to smaller and independent services. This represents a significant architectural change. Developers moved away from huge, rigid monolithic setups and embraced smaller, independent systems. [...]

High-Performing ≠ Massive: The Rise and Progression of Small Language Models (SLMs)

Have you ever needed to find a new charger for your device, only to discover that its voltage wasn’t compatible, causing it not to work or even risking damage? Without checking the actual needs of your device, you’ve probably thought that you could go with what the seller recommends as the “highest quality” rather than your device’s fitting needs. With the current utilization of AI for businesses, bigger doesn’t always mean better. Large Language [...]
