The influencer economy sells flashy AI toys while real systems shatter at scale. Notes from six months of auditing broken pipelines, the 10-level hierarchy that separates a demo from an engine, and what real AI engineering actually takes.
The sixth entry in a live builder's log. The contribution I was certain would be the centerpiece lost to the cruder approach already in the pipeline. I published the loss, because complexity has to earn its place every time.
A deeper Builder Journal entry from inside the Hyperspectral Object Tracking Challenge 2026, with code. Before a single model could matter I had to build a local scorer for an unlabeled test set and beat a stale submission template. The plumbing is half the competition.
The fifth entry in a live builder's log. A parameter sweep handed me a new best score. Three red flags said it was noise wearing a knob's clothing, so I refused to ship it. Most of competitive ML is declining to fool yourself.
The fourth entry in a live builder's log. I built a faithful local scorer, then fed it a biased test set, and it confidently signed off on a change that made me worse on the real leaderboard. A dev set built from failure cases certifies rescues, not deployments.
Expanding into Latin America is not the UK game of branding. Here is how traditional data science found the hidden, government-backed markets the incumbents never saw, and turned a sub-$1,000 trickle into a network across two continents.
The third entry in a live builder's log. My first Kaggle submission was rejected before it ever scored, thanks to a stale sample_submission file and a Google Drive download limit. The plumbing turns out to be half the competition.
The traditional international playbook says global expansion needs millions in capital and a big team. Here is how a two-person venture scaled across the UK and EU to a high revenue run rate in 90 days with zero upfront capital, and an AI intelligence system that cost under $9.
The second entry in a live builder's log. The Hyperspectral Object Tracking Challenge scores you on an unlabeled test set, so the leaderboard can't tell you your own score. Here's how I built a local scorer byte-faithful to the official one, and why measurement is half the battle.
The first entry in a live builder's log. I'm competing in the Hyperspectral Object Tracking Challenge 2026: track one object through video shot in colors the human eye was never built to see. Here's what the problem is, why it's hard, and where I'm starting on the leaderboard.
Seven unrelated AI competitions, one person, at the same time. The framework behind it was not built in a lecture hall. It was built by a broke teenager who could not stop losing at League of Legends.
Everyone fears AI will replace them. The data shows the opposite happening: the companies that cut jobs for AI are quietly hiring people back, often to supervise the AI. Here is why it's breaking, with the receipts.
