Deploying an AWS Application Load Balancer (ALB) Using Terraform
If you’ve tried building an ALB manually in the AWS Console, you already know the drill create a VPC, configure subnets, set up security groups, launch EC2 instances, create a target group, add listeners, and then double check everything because one small misconfiguration can break the whole setup. It [...]
How to Break Into Tech (With Security in Mind)
Let’s talk honestly for a second. If you want to break into tech securely, you need to think differently from the start. A lot of people say they want to “break into tech,” but very few think about structure, architecture, and security from day one. What they usually mean [...]
Stop Running OpenClaw on Your Laptop: How I Built a Secure Personal AI Assistant Using Amazon Bedrock
I'll admit. The first time I heard about OpenClaw and its features, I was obsessed. The idea of having an AI that could actually do stuff rather than just giving responses to prompts felt like living in the future. As a university student, it’s a given that I have [...]
Improving Application Security with AWS Security Agent
Modern software teams are very fast today. Code is pushed daily. Pipelines deploy automatically. Features reach users quickly. This is the success of DevOps. But security often does not move at the same speed. In many organizations, security reviews are still scheduled monthly or quarterly. Penetration tests require coordination. [...]
Real-time Personally Identifiable Information (PII) Redaction Pipeline with S3 + Lambda + Comprehend
In my previous article, I demonstrated how to use the Amazon Comprehend console to manually detect and redact Personally Identifiable Information (PII) from text files. While this hands-on method is excellent for learning the fundamentals of PII detection, it’s not practical in real-world, high-volume environments where speed and accuracy [...]
Are AI Engineers the New Full-Stack Developers?
Something has been quietly shifting in the tech industry. Job titles that used to sit in completely separate corners of a hiring platform are starting to blur together, and engineers on both sides are feeling it. The full-stack developer who's suddenly expected to integrate LLMs. The AI engineer who's [...]
The “Stateful” Video: Moving from Random Prompts to Semantic Consistency
In the early days of GenAI, creating a video was like launching a Lambda function with no database—every time you ran it, the AI "forgot" what the character looked like, what they were wearing, or even the laws of physics in the previous scene.As we hit 2026, the industry [...]
Reinforcement Fine-Tuning in Amazon Bedrock: A Practical Guide for Enterprise AI
Large language models are powerful, but power alone is not enough for enterprise AI. A model may generate fluent responses, yet still miss your company’s tone, fail structured validation rules, or produce outputs that are technically correct but operationally unusable. The real challenge is not just making models smarter, [...]
Don’t Install OpenClaw! (Unless You Read This First)
If you have been on Twitter, TikTok, or GitHub recently, you have probably seen the hype. Clawdbot (now rebranded as OpenClaw) promises something bold: a self-hosted AI employee that runs on your Mac Mini, has terminal access, and takes instructions through messaging platforms like Telegram. It sounds powerful. It [...]

Can Gemini 3 Replace My AI Toolkit?

I've always approached AI with one mindset: use whatever tool gets the job done fastest and cleanest. I'm not loyal to one model, one company, or one ecosystem. I switch between tools depending on what my day looks like. In school, that might mean summarizing academic papers. At work or during self-study, that might mean debugging code or reviewing a cloud diagram. For daily life, it might just mean drafting an email or organizing [...]

AWS Vector Databases Explained: Semantic Search and RAG Systems

The generative AI (GenAI) revolution has transformed how organizations extract value from their data. While large language models (LLMs) demonstrate remarkable capabilities in understanding and generating human-like text, their true enterprise potential is unlocked only when they can access proprietary, domain-specific information. This necessity has propelled vector databases from a specialized niche into an essential pillar of modern AI infrastructure. But First, What Are Vector Databases? A vector database, as its name suggests, is [...]

Self-Hosting Judge0: A Step-by-Step Guide Using Amazon EC2, Lambda, and S3

Judge0 is a powerful, open-source code execution system widely used by online coding platforms to run programs in secure environments. However, while it is often accessed as a third-party service, self-hosting Judge0 on AWS significantly grants you complete control over configuration and security. In fact, this level of ownership is essential for handling sensitive data or customizing language support. Moreover, self-hosting enables greater scalability, thereby allowing you to adapt the system as your requirements [...]

The Cash Cow + Investment Model: A Career Blueprint from Tutorials Dojo’s CEO

Imagine spending weeks building a course, only to watch it fail. That’s exactly what happened in 2019 to the founder of Tutorials Dojo, Jon Bonso. He had spent weeks building a React Native course. He recorded, edited, and re-recorded, hoping people would buy it. However when it finally launched, the effort didn’t match the reward. It was one of those career-defining moments where you ask yourself: “Am I even in the right industry?” Instead [...]

AWS Strands Agent SOPs – Your Natural Language Agentic AI Workflow Tool

If you're someone whose work involves AI automation or a developer, you'll know that Modern AI agents are powerful but notoriously difficult to guide with consistency. You put the same thing in twice, you get two drastically different results. There are two ways of driving Modern AI agents: Code defined workflows Fully model-driven agents Code-defined workflows offer precision but require heavy reengineering to update. Fully model-driven agents offer flexibility but can behave unpredictably. Agent [...]

What is Amazon Bedrock AgentCore?

Imagine spending months building an AI agent that integrates seamlessly into your development environment. It employs tools, responds to inquiries, and completes duties precisely as planned. But moving it to production becomes a nightmare: suddenly, you are dealing with scale problems, security concerns, authentication systems, and API interfaces. What should have been a simple deployment becomes weeks of infrastructure labor unrelated to your agent's intelligence. This production gap is the bane of countless developers, [...]

A New Player in Town: Google Antigravity

On Wednesday, Google, the creators of Gemini, one of the top competitors of popular LLMs like ChatGPT (developed by OpenAI), recently launched their first AI agentic development IDE, known as Google Antigravity. Built for a wide range of customers, it is targeted to both professional developers working on large enterprise codebases and hobbyists vibe coding in their spare time. It provides installation support for Windows, MacOS, and Linux. In the rising wave of AI-powered [...]

Neural Networks and Images with Convolution

In the age of artificial intelligence, it is common to meet the term neural network, seeing diagrams of neurons connecting to other neurons, programmers training models, and so on. Here, we will discuss how neural networks are similar to plain mathematical functions (models), how they build upon traditional linear regression, and their application to visualize images with convolutional neural networks. The usual pedagogy for learning neural networks begins with the iconic diagram: columns of [...]
