Back to original languageAbout Tarik
I develop ServiceNow portals that end-users actually enjoy using — not just ones that technically function.
With over 10 years of experience in backend development (Java EE, Quarkus, Spring), I bring a deep understanding of clean architectures, performant APIs, and secure systems. In ServiceNow, my focus is on Service Portal Widget Development, REST API Integrations, and process automation with Flow Designer.
What distinguishes me from pure ServiceNow admins: I think like a developer. Complex integrations, custom widgets, and tailor-made workflows are not workarounds for me, but my core business.
In my spare time, I advise small and medium-sized businesses in IT security — from server hardening and vulnerability analysis to NIS2 preparation.
Currently available for remote projects (part-time, 15–20h/week).
