Top SchoolTetsu Heiskanen is a multilingual translator and language services entrepreneur based in Helsinki, combining a decade of professional experience with MA-level training in Translation and Japanese from the University of Helsinki. As founder of Dekiru, he delivers precise translations (Finnish–English–Japanese) across websites, CVs, reports and manuscripts, and has hands-on experience with tools like memoQ from freelance and trainee roles.
