The Blind Leading the Blind: Chasing a Production Bug

This is a submission for DEV's Summer Bug Smash: Smash Stories powered by Sentry. Around 2016, I was working as a PHP developer at Racing Post in London. The Post is best known for horse-racing news, form and results, but behind the public-facing products sat a large collection of systems for processing all kinds of racing and greyhound data. The application I worked on used that data to produce ...

Why I'm preselling my Obsidian AI plugin before writing a line of code

Disclosure: I used an AI coding agent to collect research and draft this post. I reviewed the final copy before publishing. I started with an Obsidian plugin idea I thought was obvious. Research killed it. A different one survived, and I'm now preselling it at $19 before writing a single line of code. Here's the evidence that changed my mind, and the line I've drawn for myself. The m...

I Built a Flutter App to Make Campus Life a Little Easier

A few months ago, I noticed that students in my college were using different apps and WhatsApp groups for almost everything—buying and selling items, finding events, connecting with clubs, and sharing information. It felt messy. So I decided to build CampusHub, a Flutter app that brings those things together in one place. This wasn't just a UI project. I wanted to build something that felt like...

I Built 7 Idle Games in 30 Days: What I Learned About Incremental Design

AI Disclosure: This article was written with AI assistance. All games mentioned were built using AI-assisted development tools. The Idle Game Rabbit Hole It started with one question: how small can an idle game be and still feel complete? A few weeks later, I had shipped 7 idle/incremental browser games — each under 30 KB of vanilla JavaScript, zero dependencies, zero install. Alon...

I Built Kikar — An AI Messaging Platform That Creates Digital Versions of People

For the last few months, I've been working on Kikar, an AI-powered social messaging platform with a simple goal: What if every user could have an AI version of themselves that learns from conversations and can chat in their own style? Instead of building another generic chatbot, I wanted to explore the idea of AI personalities that evolve over time. Tech Stack Next.js React TypeScript Tailwind CS...

Getting FTDC out of MongoDB Atlas

Every MongoDB server writes FTDC, Full Time Diagnostic Data Capture, into a diagnostic.data folder next to its log. Roughly 5,700 metrics, once per second, compressed hard enough that days of history fit in a few hundred megabytes. It's what MongoDB support asks for when you open a performance ticket, and it's the difference between "the database was slow" and "the WiredTiger ticket pool hit zer...

I ran Lighthouse on 269 Shopify stores. The median mobile score was 48.

I spent a July weekend running the Google PageSpeed Insights API against 269 live Shopify and DTC storefronts, one mobile audit each. I expected mediocre scores. I did not expect the biggest brands to be the worst offenders. Here is what the data says, and what almost every store gets wrong. The headline numbers Median mobile Performance score: 48 (out of 100) 53.4% of stores score...

Did the client read my proposal? What an open tells you, and the one thing you must never do with it

You spent two days on it. You attached it, wrote three careful sentences in the body, and pressed send. That was Tuesday. It is now Friday and there has been nothing at all. That silence is why a lot of freelancers and small agencies install a read receipt tool the week after sending their first serious proposal. I build one, so treat this as an interested account. It is also the article where I ...

Did the recruiter open my application? What a read receipt can and cannot tell you

Applying for a job is one of the few situations where you send something important and get nothing back at all. Not a rejection, not a delay, not an acknowledgement. Silence, for weeks. That silence is why so many people install a read receipt tool right after sending an application. I build one, so this is an interested account. It is also the article where I argue that the tool answers a smalle...

One API key across OpenAI, Claude and Gemini: how to compare token cost per model

Bottom line: if you want one API key across OpenAI, Claude and Gemini and you're choosing mainly on token cost, put a thin router in front of your app and let it price each request before sending it — with per-model pricing pulled from the same API you're calling, not from three vendor pricing pages you'll forget to re-read. For a two-person startup that buys you one credential, one place to compa...

Give Your Angular Modal a URL: Three Router-Based Approaches

Opening a modal is easy. Giving it a URL, and making that URL behave like a real part of the application, is where things become interesting. Let’s look at three ways to connect a modal to the modern Angular Router, including the trade-offs that are easy to miss. Why route a modal at all? The usual modal starts with a click handler: <button (click)="openEditDialog(product.id)"&g...

I checked who comments on my MCP posts. Most of the good ones are bots.

I've published seven posts about the MCP ecosystem in a week, all built on measurements — endpoint health, schema drift, tool ambiguity. They drew a decent number of comments, several of them genuinely sharp. One reframed my whole approach and I thanked the commenter for it. Then I did to the commenters what I'd been doing to MCP servers: I measured them. Most of the best comments came from auto...

What I Learned Shipping 90+ Mobile Apps with AI Coding Agents

Over the last year I've shipped more than ninety mobile apps to the App Store and Play Console, almost all of them built with heavy help from AI coding agents (Claude Code, mostly, with a mix of other tools along the way). That number sounds absurd until you understand what most of these apps actually are: small, focused utilities and niche games built by a team of one, not ninety separate startup...
