Back to original languageAbout Kai
Hello, I am Kai Jettka – a freelancer with a technical background and over 20 years of professional experience in customer service, organization, and structured work.
I offer support with:
Data maintenance and data entry
Text creation, proofreading, and document preparation
virtual assistance and digital administrative tasks
reliable communication with customers and teams
I work calmly, carefully, and independently – ideal for tasks that require concentration, reliability, and clear communication.
As a technically savvy individual with experience in customer contact, assembly, and digital structure, I bring practical thinking, service understanding, and teamwork skills.
In my free time, I have been an enthusiastic gamer for many years (including Guild Wars 2, World of Warcraft, Enshrouded) – not professionally, but with great interest in technology, game systems, and digital communication.
I look forward to long-term or project-based collaboration – fully remote, flexible, and on time.
