Dockerizing a Video Platform: From Dev to Production

Running TopVideoHub across 9 Asia-Pacific regions means the cron fetcher, the PHP app, and the SQLite database all need to behave identically in development and on the actual LiteSpeed servers. Docker made that guarantee possible. Here is how I containerized the stack. Why Docker for PHP+...

AI Voice Agent Pricing vs Human Receptionist: What 40+ Deployments Taught Me About True Cost

The advertised price is almost never what you pay. Vapi says $0.05 per minute. That is true if you ignore the LLM, the transcription engine, the voice synthesis, and the telephony carrier. Add those in and you are at $0.15 to $0.31 per minute before your first call ends. I have deployed AI voice ag...

My AI-Assisted workflow

You open a chat, describe what you want, iterate on the output, and ship something that more or less works. It feels fast. The features work, technically. But nobody, including me, fully understood what is there. Edge cases nobody thought to handle, architecture that made sense in the moment but did...

You Vibe-Coded. Now What?

I was at an AI event a few weeks ago when someone casually mentioned they'd vibe-coded their own CRM. Prompted into existence in a day to support their use-case. It sounded impressive in the moment. But it got me thinking about a question that keeps showing up on X, on LinkedIn, in Slack channels: ~...

Stop Coding Through Remote Desktop. Use VS Code Remote Tunnels Instead

There is a pattern I keep seeing with customer environments. You get access to a VM for development. The code stays there. The dependencies are already there. The network access is there too. On paper, it looks fine. Then reality starts. You are expected to work through Remote Desktop, as if soft...

Why I Built TokenBar: AI Spend Should Not Be a Monthly Surprise

A lot of AI cost advice starts too late. It tells you to review the bill after the damage is done. That never worked for me. The real problem is not that AI is expensive. The problem is that the expensive part happens quietly. One more prompt. One more rewrite. One more huge context dump. Then yo...

Building Robust AI Agent Memory Systems in 2026

Picture this: you've built an AI agent that can handle customer support tickets brilliantly, but it keeps asking the same customer their name and order number in every conversation. Sound familiar? We've all been there — creating agents that work perfectly in isolation but have the memory span of a...

I caught my AI agent posting a customer's SSN to Slack. Here's what I built to stop it.

Two months ago I was testing a support automation I'd built with CrewAI. The agent reads Jira tickets, pulls customer context, and posts a summary to the team Slack channel. Simple workflow. The kind of thing every second startup is building right now. It worked perfectly until a ticket came throug...
