About Luca

Your teams spend hours on conflicting Excel files, reports nobody reads, and data nobody truly understands.
I fix that.
Specifically, I build dashboards that run themselves, automate repetitive tasks, and develop ML models that actually make it into production. Not POCs. The real deal.
I've worked on credit scoring, fraud detection, LLM agents, data pipelines, and production dashboards. In finance, insurance, and the oil industry in Scotland.
What interests me is your business problem, not selling you a tech stack. If the solution doesn't save time or change a decision, it's useless.
Data and AI aren't just my job; they're what I spend my evenings building personal projects on.
Have a persistent problem? Describe it to me in a few lines, and I'll get back to you within 24 hours.

Luca continues to be an invaluable asset to our workflows. Because he processes data using our bespoke internal software, he occasionally encounters bugs and system imperfections. Thanks to his proficiency in coding, Luca doesn't just report these issues—he actively helps fix them on the fly. He works remarkably quickly, communicates clearly, and treats our internal tools with the care of a core team member. Highly recommended!

For this project, Luca handled the intricate task of parsing binary downhole tool data into 1Hz, 100Hz, and 1500Hz resolutions. Merging this with surface drilling data required time-clock synchronisation and clock-drift corrections. Luca executed this flawlessly.
