Hi.I’m Tom.
Tom de Leeuw, engineer. I investigate the problem and do the engineering myself.
I’ve worked as an MSP engineer, built integrations and automations, and led a systems administration team. That means I know both the underlying engineering and the daily pressure on a service desk and operations.
I’m usually brought in when a problem sits between systems or teams: everyone sees part of the symptom, but nobody has the time or access to trace the full chain and fix it properly.
