Focused blurbs on concepts people struggle with—Total Cost of Ownership, architecture patterns, decision frameworks. Part wiki, part blog, part practical guide.
Total Cost of Ownership
TCO isn't the sticker price. It's everything you pay, plus everything you give up. Most decisions fail because they optimise for the wrong number.

What does '105+ automated tests' or '99.7% accuracy' actually mean? Data quality isn't gut feel—it's measurable, repeatable, and defensible. Here's how it works.
Read more →dataConfidence Scoring
Not all claims are equally trustworthy. Confidence scoring tells you how much weight to give a piece of data—so you can decide when to act and when to dig deeper.
Read more →architectureError Recovery & Graceful Degradation
AI agents fail. APIs go down. Networks hiccup. Error recovery is how you keep systems working when things break—instead of crashing, you fall back to something that works.
Read more →architectureSheets-First Architecture
Your strategy team lives in spreadsheets. Your services need fast data. Sheets-first architecture bridges that gap—without forcing everyone to 'learn the database.'
Read more →architectureVendor Lock-in
Vendor lock-in isn't just 'we use their API.' It's the cost of leaving—the rebuild, the data migration, the workflows you can't take with you. Here's how to avoid it.
Read more →decision-makingBacktesting & Strategy Validation
Backtests can lie. Survivorship bias, lookahead bias, and overfitting make strategies look great in the past and fail in the future. Here's how to validate properly.
Read more →dataData Pipelines & Transforms
Raw data rarely lands ready to use. Data pipelines move, clean, and reshape it—so decisions run on trusted inputs instead of messy exports and manual fixes.

Start with SQLite for zero-setup MVP. Scale to Postgres when you need concurrency. Same code, different connection string—if you design for it.
Read more →dataEPR & Environmental Compliance
Extended Producer Responsibility (EPR) means you're on the hook for your packaging's end-of-life. Fee schedules, reporting, and disclosure rules vary by region—and they're getting stricter.

Not every process is a straight line. Graph-based workflows handle branches, loops, and conditional paths—the way real business processes actually work.
