# Tamperan

> Fractional and advisory leadership, technical due diligence and product engineering. Enterprise experience, deliberately kept small. UK-based.

Run by Shane Wright, who spent 25 years building software businesses, co-founded two and was CTO of both, and sold both. Work is delivered by him with a small group of long-standing partners brought onto a project when it needs them.

## Writing

Dated write-ups of specific decisions and what they cost.

- [Handing the easy tickets to a free local model cost 1.65x more](https://tamperan.com/writing/2026-08-25-local-model-handoff/): I built a harness to grind the mechanical backlog tail on a local Ollama model and measured what it actually saved. Across three real tickets the local-model path cost 1.65x the Claude tokens of just doing the work, and every output needed fixing before it could merge.
- [Why your OpenTelemetry build broke, and how to check the whole set](https://tamperan.com/writing/2026-08-17-otel-version-mismatch/): OpenTelemetry ships as several modules with different version numbers that are all one release. Go has no idea. Here is how to tell which versions belong together, why it breaks, and a check you can run in CI today.
