Exit intent that works on mobile, not just desktop

Originally published on my site, arafatcro.dev/guides. You copy the exit-intent snippet, it fires nicely when the cursor heads for the close button, and you ship. Then you check the data and half your traffic never triggered it, because they were on phones and a phone has no cursor to chase. Exit intent is not one trick. It is a different signal on each device, fired once, and built so it does not become the thing people leave over. The standard snippet listens for the mouse leaving the top of t

Stop building custom wrappers for your ML models.

I spent three days last month building a specialized API wrapper for a simple Scikit-learn model. Not because the logic was hard—it wasn't. Because I wanted Cursor to be able to run inference on our churn prediction data without me having to manually copy-paste JSON results into the chat. It is a classic engineering trap: the 'Integration Tax.' You have a working Modelbit workspace, you have your weights deployed, and you have an AI agent that could theoretically use it. But instead of using the

Collect client feedback on a website without endless revision rounds

Most revision rounds don't spiral because the client is picky. They spiral because the feedback lost context on the way to you. Here's why that happens, what agencies try, and how to make each note clear enough to fix the first time. A revision round is supposed to be one loop: client looks at the site, says what's off, you fix it, they look again. The trouble is that most of the feedback you get can't be acted on as-is. "The hero feels cramped on mobile." Which phone. Which section. Cramped how

Sync a mailbox into your own database with Nylas

You want your app to have its own copy of a user's email: to search it fast, run analytics over it, or feed it to a model without hitting the provider on every query. The naive version is a one-time pull that's stale the moment it finishes, because new mail keeps arriving and old mail gets read, moved, and deleted. A real sync is two jobs working together: backfill the history once, then track changes forever after. This post builds that out with the Email API and shows the CLI shortcuts for tes

How much does context cost an AI coding agent? grep vs graph vs LSP, measured across 936 runs

In my last post I described graphlens — what it does, how it works — and along the way I casually claimed that an agent "burns tokens grepping around a repo." I gave exactly zero numbers to back that up. This post fixes that. Here are the measurements, the data, and a reproducible harness. Spoiler: the conclusion is not the one I expected going in, and that's the interesting part. I took one agent (Claude Code), changed exactly one thing — which MCP server feeds it code context — and ran it over

Is OpusClip’s subscription model becoming a real pain point for creators?

I've been looking into AI tools like OpusClip and trying to understand how creators actually feel about them in practice. From what I see, these tools are powerful, but they often come with subscription pricing, usage limits, and credit-based systems that can become restrictive if you're producing a lot of content. I'm currently exploring an alternative idea: a desktop application that generates clips locally on your computer. The goal would be to give users more control over their data and pote

Correlation IDs in ASP.NET Core: A Practical Guide for Backend Engineers

When we build backend systems, especially APIs and microservices, debugging production issues is rarely about reading one log line. A single request may pass through an API Gateway, an authentication service, an order service, a payment service, a message broker, and maybe a background worker. Each component may generate logs. But without a shared identifier, it becomes difficult to understand the full journey of that request. This is where a Correlation ID becomes useful. A Correlation ID is a

I'm 18, Self-Taught, and I Built an AI Study App for Nigerian Students — Here's How

When I sat down to build Aveliq, I had one goal: give every Nigerian student access to tools that actually help them study smarter. Not a repackaged ChatGPT wrapper. Not another generic quiz app. Something built specifically for WAEC, JAMB, NECO and Post-UTME — the exams that actually determine the trajectory of millions of Nigerian students every year. My name is George Erubami. I go by GeoCode. I'm 18 years old, self-taught, based in Ibadan, Nigeria. I built Aveliq end to end — frontend, backe
