Resurface Claude Code Usage Across Your Team with CloudWatch OTEL (No Lambda)

I've been building AI tooling infrastructure to empower a team of 50+ software engineers to do vibe coding safely. We went from 3 engineers using AI full-time to 50+ in 6 months — including non-engineers. (I co-presented on this journey at AgentCon Hong Kong 2026.) One thing we learned: you can't improve what you can't measure. Once you give a team AI coding tools, you want visibility into how th...

Why I Built an AI Visibility Tool When Semrush Already Had One

Why I Built an AI Visibility Tool When Semrush Already Had One Semrush shipped their GEO tool first. So did Otterly. So did half a dozen enterprise SEO suites. So when people ask why I built SignalixIQ, I get it. The market looks crowded on the surface. Here's the honest answer: the existing tools are built for enterprise SEO agencies, not for individual merchants. I tried to use them ...

Hello DEV — I'm Mehtab Riaz, and I'm excited to join this community

I'm a software developer who cares about clear, reliable, and useful products. Day to day, I work across the stack with a strong focus on maintainable code, solid interfaces, and performance—the kind of details that keep software pleasant to ship and to live with after launch. Lately, a lot of my work lives in the JavaScript / TypeScript ecosystem (React, Next.js, modern tooling). I like turning ...

Portable LLM on a USB Stick: I Built Offline AI That Runs Anywhere [2026 Guide]

Last month I was sitting in a client's office — no Wi-Fi, a locked-down corporate laptop, and a deadline to rewrite 40 API endpoint descriptions. Every cloud-based AI tool I normally rely on was completely unreachable. So I pulled a Samsung T7 SSD from my bag, plugged it into the USB-C port, and had a portable LLM on a USB stick generating clean documentation in under two minutes. No internet. No ...

Building Cuevora: what a teleprompter taught me about building software people can trust

I did not start out trying to build something impressive. If I am being honest, I just wanted to build something that actually worked… without trying to squeeze money out of people for basic features. I had used a few teleprompter apps before. Some were fine at first. Then slowly, things would disappear behind paywalls. Adjusting speed. Saving scripts. Even simple usability features. It just did...

I Built a B2B Lead Generation Tool for Freelancers - Here's What I Learned

The Problem Freelancers and small agencies spend an exhausting amount of time on client acquisition - finding leads, writing cold emails, tracking responses, and creating proposals. Most tools out there are built for enterprise sales teams, not solo operators. I decided to build something different: a B2B lead generation tool specifically designed for freelancers and small agencies. ...

Unhandled CSS Ruining Life

There is a moment in the life of almost every mature frontend when CSS stops feeling like a tool and starts feeling like archaeology. You open one screen and the primary button has one height. On another screen, it is almost the same height, but not quite. Inputs look consistent until you open a modal. Selects behave until a page level override wins. Somewhere in the codebase there is a global sty...

I Built a Skill Registration Framework for AI Agents in 3000 Lines of TypeScript

I was tired of every AI agent framework having a different way to register tools. So I built one that works for all of them. ## The Problem If you've built AI agents, you know the pain. Every framework — LangChain, AutoGen, CrewAI, OpenClaw — has its own way to define tools and skills. Want to add a weather API? Different syntax everywhere. Want credentials? Good luck figuring out each one's app...

Cloud sync is a feature you’re paying for with your privacy

Open a new app. Create an account. Verify your email. Choose a plan. Grant permissions. Now you can take notes. This is the default in 2026. And most developers just accept it. I've been building local-first terminal tools for a while now, and the more I do it, the more convinced I am that the industry defaulted to cloud sync not because it's better for users, but because it's better for retenti...

Value Objects, Entities, and Aggregates in Go — Without a Framework

Domain-Driven Design in Go doesn't look like DDD in Java. There are no annotations, no repository interfaces from a framework, no @Entity markers. The building blocks — Value Objects, Entities, and Aggregates — emerge from Go's type system and encapsulation rules. Here's how each pattern appeared in a security CLI through refactoring, with the actual before/after code. Value Objects: Eq...
