About Me

I am a versatile technology professional with a unique blend of IT, security, sales, and marketing expertise, built across Helsinki, Nairobi, and Dublin. I specialise in leveraging technology to drive business growth and enhance customer satisfaction.

My career spans the full customer lifecycle — from technical infrastructure and helpdesk support to CRM platform management (ServiceNow, HubSpot, Zendesk) and multi-channel marketing strategy. I bring ITIL-grounded incident management together with commercial acumen.

Currently based in Dublin, I am furthering my expertise with an SAP Business Analyst certification. I hold a BBA in Marketing, Media & ICT and a software development bootcamp credential to complement my IT foundation.
