The expert witness who codes: who signs off on what we do
Pedro Mulero Sánchez is a court-appointed expert witness in road transport and logistics, a member of ASPEJURE and the founder of Tarraco App Lab. How you get from a tachograph chart to writing software.
On almost every agency website there is a team page with photos and made-up job titles: “Head of Digital Strategy”. Here the team is small and it’s worth knowing who leads it, because it explains how we work.
Who he is
Pedro Mulero Sánchez is a court-appointed expert witness in road transport and logistics. He is a member of ASPEJURE, the Asociación Profesional Colegial de Peritos Judiciales del Reino de España (a professional association of court expert witnesses in Spain), with membership number 03667. That number can be checked in the association’s public register, which is how all credentials ought to be shown.
He works from Tarragona and is the founder of Tarraco App Lab.
Twelve specialisms and why there are twelve
A court expert witness declares the subjects on which they can give an expert opinion. His are these:
Vehicle mechanics and electrics. Hidden defects in vehicles. Vehicle valuation. Electric vehicles and charging points. Digital and analogue tachographs. Driving and rest times. Commercial vehicle valuation. Forklift trucks. Workplace accident investigation and risk prevention. Working-time recording and monitoring. Road traffic accident reconstruction. Impact biomechanics. Vehicle damage assessment.
They look like a lot until you see that they are three blocks that overlap. The vehicle from the inside. The accident and what happens afterwards. The driver’s employment relationship. A lorry that overturns at four in the morning can end up in all three places at once: the condition of the vehicle, the reconstruction of the crash and the hours its driver had spent at the wheel.
What the tachograph says about those hours is often what decides the case.
How you get from there to making software
Not out of a passion for computing. Out of sheer frustration.
Analysing a tachograph chart or a driver card download is repetitive work full of rules. Doing it by hand takes hours and invites mistakes that then have to be defended in front of a judge. The first program was born for that: so that the analysis would be reproducible, which is what matters in an expert report. The same input file has to give the same result, every time, even if someone else repeats it two years later.
That demand gave rise to three habits that are now in everything we do.
The first is traceability. Every number that appears in a report must be traceable back to the data it comes from. If it has no source, it doesn’t get printed.
The second is determinism. The tools give the same result for the same input. It sounds obvious and it isn’t: a lot of software slips in the system date or a random number where it shouldn’t. Then the result can no longer be reproduced.
The third is caution with data. A driver’s ID card, their working hours and sometimes their medical report pass through an expert examination. That shapes where things are stored and what leaves the computer. That’s why Oriana Mail runs entirely locally. It’s also why the websites we build load nothing from third parties before the visitor accepts cookies.
What this has to do with your website
More than it seems, though not on the technical side.
An expert witness writes to be read by someone who is going to pick holes in it: the lawyer on the other side. That teaches you not to state anything you can’t back up, to cite the law with its article number and to tell what you know apart from what you assume.
Carried over to a commercial website, it means that here we don’t write phrases like “industry leaders” or promise top positions on Google. If we put a figure on this blog, it’s because it has been measured. If we cite a law, we’ve opened it in the BOE (Spain’s Official State Gazette) before writing about it.
It’s less flashy than the alternative. It holds up better in a conversation with a client who asks questions.
Where to see his work
The expert witness website is Perito Camión. For tools for the sector there is Driver Solution. For employment information in the transport sector there is Carretera Nacional, which is free and sells nothing.
And if you need an expert report, that’s commissioned there, not here. We build websites.
