Our Thinking
Notes from the build
Practical takes on software development, AI integration, and shipping products that hold up.

The AI Retrofit Log: Six Features We Added to Products Already in Production (and the Two We Turned Off)
A feature-by-feature account of retrofitting AI into live products: where the call was inserted, latency budgets, cost per call, fallbacks, human review gates, and the two features we shipped and then removed.
The Back Office Work We Deleted: A Task-by-Task Automation Audit from MOVE & MEET and Plodovi
A concrete inventory of the recurring manual admin tasks two small operations ran every week, which ones we automated, which ones we left alone on purpose, and the three automations we reverted.
OpenAI vs. Anthropic vs. a Local Model: The Selection Matrix We Ran for Three Client Features
How we chose between OpenAI, Anthropic, and a self-hosted model for three production features: consent-bound health data, marketplace product copy at scale, and support triage. The constraints that actually decided it, and what broke when we switched providers.
From Spreadsheets to a Custom Internal System: The Migration Playbook We Ran for MOVE & MEET and Plodovi
A practical, step-by-step account of replacing spreadsheets with a custom internal system: auditing formulas for hidden business rules, modelling entities versus events, cleaning dirty history, running parallel, and cutting over without losing operator trust.
The TypeScript Code Review Checklist We Run on Every SvelteKit and React Native Pull Request
Jaspero's per-PR review checklist for TypeScript codebases: type boundaries, Zod contracts, Firestore rules and queries, SvelteKit server boundaries, and React Native re-render checks, plus the comment classes we deleted and automated instead.
Rebuilding a Fitness Community App From Scratch in React Native: A 14-Week Build Log
A week-by-week build log of taking MOVE & MEET, a London fitness community, from spreadsheets to a shipped iOS and Android app in React Native: scope cuts, feature order, App Store rejection, TestFlight builds, and the iOS-versus-shared code split.
