TERRASSA, CATALONIA — PORTFOLIO

Pau Esmerats

▸ Software Engineer

I build systems that quietly do the work: automation that removes toil, AI that makes knowledge findable, and interfaces people actually enjoy using.

About

Software engineer with a year-plus shipping enterprise systems, AI integrations and full-stack products end to end.

I cut IT technician workload in half with PowerShell automation, and made internal documentation answerable with a retrieval-augmented agent used by 500+ people. I care about reliability, clear interfaces and software that keeps working after launch.

I'm most at home in JavaScript, React and PowerShell automation, with a working knowledge of Python and SQL.
