Why Work With Me

As former official Tealium & Commanders Act support, I have deep knowledge of these products. I've handled hundreds of complex incidents.

At Converteo, I also managed end-to-end projects: scoping, team coordination, client relations. I combine this project management experience with deep technical expertise in JavaScript and TMS to create custom solutions.
