Delving into the Rabbit Hole of Agentic Coding: What Went Wrong, What Worked, and What I Should Have Done Differently

TL;DR: In this post, I go through my experience attempting to solve real problems with the help of AI agents and agentic software development 🤖. I walk through the steps I took 👣, the thought process and decisions I made along the way 🧠, from planning to development to testing 🧪. This is a story of my attempt to build two tools that solve day-to-day workflow issues, one that failed and one that su...

30-Day Cloud & DevOps Challenge: Day 6 — Dockerizing My React Frontend

Yesterday, I packaged my backend into a Docker container. Today, I did the same for my React frontend. But there's a twist, frontend containers are DIFFERENT. No Node.js running. No npm start. Just pure, static files served by nginx. And I learned why nginx is the king of web servers. First: How Frontend Docker is Different Backend Container Frontend Container Runs Node.js ...

I Built an AI That Psychoanalyzes Your Friend Group — Meet brother.skill

Every group chat has the same cast of characters. The guy who hypes everything. The one who roasts you with surgical precision. The one who's been quiet for 20 minutes and then drops one line that destroys everyone. And the meme lord who hasn't used actual words since 2019. I built an AI skill that distills these people. What is brother.skill? It's an AI agent skill that builds perso...

55% of Construction Software Vendors Hide Their Pricing. I Know Because I Checked All 570.

55% of Construction Software Vendors Hide Their Pricing. I Know Because I Checked All 570.

I tried to buy construction software last year and gave up twice. Capterra kept showing me Salesforce. G2 kept showing me Monday.com. Both platforms treat "construction" as a filter tag stapled onto generic SaaS, and the results punish anyone looking for something a framing crew can actually open on a phone at 6am. So I built ConTechFinder. A directory that only lists construction software. No C...

Engineering a Real-Time Stadium Management Dashboard in Under 1MB

Introduction Have you ever been at a major sporting event, sitting through the first half, only to spend the entire 15-minute halftime waiting in line for the bathroom or a burger? This is the ubiquitous "Wait Time Dilemma" in the Physical Event Experience. At peak capacity, attendees naturally swarm to the closest facility, unaware that an identical facility just one sector over is completely e...

Building Igris: Crafting My Personal AI Agent & Knowledge Codex

As developers, we leave digital footprints everywhere—through our code, our portfolios, and our articles. But what if people could just talk to a digital version of us? That question led me to build Igris, a personal AI shadow agent and knowledge codex designed to answer questions about me, complete with my own personality. You can try out the live chat interface here: Agent Igris, and check out ...

I build a Web Component UI Kit.

I didn't wake up one day and decide to build a UI kit. Like most things I've built, it started as a solution to a problem I had, for a project nobody asked for. I spin up a lot of side projects in my free time, the kind that will never see the light of day. Little things that keep me entertained and challenged, and honestly, keep me sharp on technology I'd otherwise only read about. About a yea...

5 .cursorrules Patterns That Make Cursor Actually Reliable

5 .cursorrules Patterns That Make Cursor Actually Reliable If you're using Cursor (or VS Code with Cursor), you've probably experienced the frustration of inconsistent AI suggestions. You write a .cursorrules file, but the AI sometimes ignores it, interprets it wrong, or gives you code that violates your own conventions. The problem isn't Cursor. It's how the rules are written. After ...

Understanding Internal Covariate Shift and Residual Connections: Beyond Activation Functions and Optimizers

"No man ever steps in the same river twice, for it's not the same river and he's not the same man" - Heraclitus When Going Deeper Made Things Worse In my last post, we built CNNs that could see.

Give Your OpenClaw Agent a Brain with Hjarni

OpenClaw is impressive out of the box. You message it, it acts. It runs on your machine, connects to your tools, and works while you sleep. But it starts from zero every time. Your notes are in Notion. Your decisions are in Obsidian. Your playbooks are in a Google Doc you haven't opened in three months. You keep re-explaining yourself. Hjarni is an AI-native knowledge base with a built-in MCP s...

Is Axios Dead? I Built a Policy-First HTTP Client for TypeScript

Beyond Axios: From Imperative Requests to Declarative Transport Policies with pureq Most TypeScript teams still start with one default answer for HTTP: "just use Axios". That was a good answer for years. But today, the core challenge is no longer sending requests. It is designing transport behavior that stays reliable, observable, and maintainable as systems grow.
