Construction data,
AI agents, and
whatever broke
this weekend.

~/full-stack dev · project controls · local AI

Twenty years of code, ten of them on billion-dollar EPC projects. I build RAG pipelines and agentic workflows for the messiest data in industry, run a rack of 3090s at home, and write down what breaks (a lot breaks).

Lab Notes

The blog. What broke, what I learned, and what it cost. Roughly monthly, always longer than planned.

Automated BIM takeoff platforms assume your model followed the rules. Real models never do. So an AI agent drove Navisworks headless.. and five trades of takeoff took four days.AIAgentsConstructionBIM

I Built a Bot Army to Attack My Own Game Server, and 45 of Them Took It Down

My movement bots said the server could hold hundreds. Then I taught them to swing a sword and the whole thing fell over at 45.. which is how I ended up shopping for CPUs instead of RAM.Game DevelopmentSelf Hosting

My friends said the new model on my rig was drunk. Root-causing that from LiteLLM request logs turned into pricing every token my GPUs have ever produced.. and a $961 cloud comparison.AISelf Hosting

Who's Writing This

Self-taught on MMORPG servers, ten years in construction project controls, and four years at Fireship helping grow the channel from 1M to 4M subscribers. These days most of my week is AI agents and industrial data. I've worn a lot of hats (some of them hard hats).

What People Say

I began working with Tony several years ago on a basic website with some functionality. He delivered exactly what I asked for and has never left our side. Every request, every question…he comes through! I couldn’t ask for a better person to hold our hand through all of the small things we don’t understand.

We've worked with Tony on numerous projects and have always found his meticulous attention to detail and upbeat, can-do attitude to be hugely empowering. He writes clean code that we can easily build upon and he is able to quickly shift pace to accommodate changing requirements - an enormously useful trait to have!

I had a great experience working with Tony. He is a skilled web developer, responsive, efficient, and focused on getting things done. With a well-defined scope, the work proceeded smoothly and matched what we planned. I would confidently recommend him to anyone looking for reliable development support.

Let's Talk Shop

Ugly data, an AI idea that needs to survive contact with reality, or a web app that should already exist.. I'd like to hear about it.
