App Deployment Is More Than Just Writing Code
When I first started learning about application development, I thought creating an app was mostly about writing code, designing the interface, and making sure the features worked. Once the application was built, I assumed the next step would be to publish it and let people use it. However, as [...]

Building Production AI Agents on AWS: AgentCore Harness, Strands 1.0, and the Multi-Agent Architecture that Actually Ships

Six months ago, "AI agents on AWS" meant duct-taping together Amazon Bedrock, a Lambda function to handle tool routing, DynamoDB for session state, CloudWatch for tracing, and a LangGraph loop you prayed would recover from a network hiccup mid-reasoning. Every team was reinventing the same infrastructure. Every demo worked; most productions did not. That changed on June 17, 2026, at AWS Summit New York, where Dr. Swami Sivasubramanian (VP of Agentic AI) announced what [...]

Detect Report React Rethinking the Manual Incident Response Playbook

In June 2026, nineteen Philippine government websites, including those of the Senate, the House of Representatives, and the National Bureau of Investigation, were defaced within a single week by a hacktivist group calling itself "Nullsec Philippines." By the time the Department of Information and Communications Technology (DICT) issued its statement, the damage was already done and the story was already spreading. This is the reality of modern cybersecurity: attackers move in minutes, but most [...]

Automating Publications with Claude, Canva, and n8n

Every business that runs a social media page knows the same repetitive cycle. Pick a topic. Write a caption. Design a graphic. Post it on schedule. Repeat tomorrow. Multiply that by every campaign, every seasonal push, every recurring content series, and it becomes a real operational cost, not just a marketing task. That repetitive cycle is exactly what a project called Automating Publications was built to solve. It is a working, experimental content pipeline [...]

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 for assignments?" If you're a content creator, perhaps you've asked yourself at least once: "Who actually owns AI-generated content?" Or maybe you've come across AI-generated [...]

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?

Why [...]

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, and its depth can vary with workload, time pressure, and security experience. Meanwhile, deterministic scanners provide valuable coverage, although their findings are not always presented [...]
