AI Ethics Explained: How to Use Artificial Intelligence Responsibly
Have you ever used ChatGPT to help explain a difficult topic? Maybe you've asked Gemini to summarize a lengthy article, generate ideas for a school project, write an email, or even use Claude for brainstorming concepts. If you're a student, you've probably wondered: "Is it okay to use AI [...]
Fine-tuning an LLM for natural Tagalog speech
If you're an ML engineer or a technical lead planning to pre-train a large language model (LLM) for Tagalog or Taglish, how do you start? In this article, we walk through the process of defining a target voice, building a data pipeline, running a QLoRA training experiment, and evaluating [...]
Building Diffender: A Serverless AI Security Reviewer for GitHub Pull Requests with Amazon Bedrock
A pull request can pass its tests, satisfy its acceptance criteria, and still expose a production credential in one line of code. Diffender is an Amazon Bedrock pull request reviewer built to identify that kind of risk before the change reaches the main branch. However, human review remains essential, [...]

CI/CD Crash Course: From Junior to Senior Developer
Continuous Integration and Continuous Delivery/Deployment (CI/CD) is the backbone of modern software teams. It's not just a buzzword for your resume — it's the automated pipeline that takes code from "it works on my machine" to "it works in production, reliably, every time." Understanding CI/CD deeply, not just using [...]
Everything You Need to Know About Harness Engineering
AI agents can now write code, browse the web, and run for hours without a human watching. Ask one to build a feature, and it might open ten files and call five tools. It can make a hundred small decisions before it ever shows you a result. That is [...]
Should the Philippines Make Its Own Local Large Language Model?
As countries all around the world are beginning to invest in their own large language models, the same question keeps coming up in Philippine tech circles: should the country build one, too? If we do, would it be cost-effective? And if it is, would it be beneficial? As [...]

How to Balance Business Goals with User Needs in UI/UX: A Data-Driven Approach

Ever designer eventually runs into the same challenge: balancing business goals with user needs in UI/UX. Users want fast, free, beautiful experiences with no friction anywhere, while the business wants high conversion rates, low hosting costs, and a fast time-to-market. These two wish lists are not always opposites, but they often pull in different directions, so "just build what users want" is rarely enough guidance on its own. Bridging that gap is not purely a [...]

UI/UX Design: Speeding Up the Creative Process with AI

If you have ever stared at a blank Figma canvas with a deadline looming, whether that is a thesis defense, a hackathon demo, or a personal app you finally want to ship. You already know that speed matters as much as polish. A traditional UI/UX workflow covers research, wireframing, high-fidelity mockups, and developer handoff, which can take weeks in a normal product cycle. Most people building on a deadline simply do not have weeks [...]

Agentjacking: How Fake Sentry Errors Hijack AI Coding Agents

AI coding agents like Claude Code, Cursor, and Codex now do far more than autocomplete. They read source code, query observability platforms, open pull requests, and run terminal commands on developer machines. That expanded access is useful, but it also creates a problem most security teams have not accounted for: when an agent reads data from an external tool, it often treats that data as trustworthy. A new attack class called agentjacking takes advantage [...]

Amazon Quick & Agentic AI: Understanding the Tools Behind Your AI-Powered Workflow

AI is no longer just a tool that answers questions. It is becoming something that takes action, runs workflows, and works alongside teams the way a capable colleague would. Amazon Quick is AWS's take on what that looks like in practice, and this article breaks down what it is, how it works, and why the infrastructure behind it matters. What is Amazon Quick? Imagine asking one platform to pull your sales data, automate a [...]

Build AI Apps Faster with Google AI Studio and Gemini

Artificial intelligence has become an essential part of modern software development. It helps developers build applications that understand natural language, generate content, analyze documents, write code, and automate complex tasks. While large language models (LLMs) make these features easier to use, integrating them into real applications still takes time. Developers must configure API authentication, choose the right model, design prompts, and set up supporting infrastructure before they can start building. Google AI Studio simplifies [...]

OpenRouter Explained: Access Multiple AI Models Through One API

The rapid advancement of generative AI has given developers access to an ever-growing collection of large language models from providers such as OpenAI, Anthropic, Google, Meta, Mistral AI, and xAI. Each model offers different strengths, whether in reasoning, code generation, content creation, multilingual support, or cost efficiency. While having multiple options is beneficial, integrating several AI providers into a single application often introduces additional complexity. Developers must manage different API endpoints, authentication methods, SDKs, [...]

Build Your Own JARVIS AI Chatbot Interface using Vercel

Have you ever watched Tony Stark boot up his suits and wished you had your very own J.A.R.V.I.S. to help you code, research, or just manage your day? If you are just starting out with web development, you have probably noticed that most AI chatbot tutorials look exactly the same. They feature soft, rounded gray-and-white chat bubbles that look exactly like those in a smartphone's default texting app. They work perfectly fine, but they [...]

Expo & React Native: Understanding the Tools Behind Your First Mobile App (2026)

Have you ever had an app idea that you wanted to build? Maybe you searched, “What’s the first step to creating a mobile app?” only to end up asking, “Why do I need all these tools before I can even build a simple app?” Many beginners expect mobile development to start with designing screens and writing code. Instead, they often find tutorials introducing several unfamiliar tools and frameworks, along with instructions on how to install [...]
