About Jan-Kasper

Software Engineer de 25 ans avec une forte appétence produit et une bonne compréhension business.

Je travaille en startup à Paris, après avoir fait le MSc X-HEC Entrepreneurs, un échange à UC Berkeley, et 5 ans à Hetic où j'ai appris à coder, faire du design et du marketing digital.

J'ai fait plusieurs stages en Product Management (Ouihelp, HostnFly), puis 1 an et demi (stage et alternance) chez Matera en tant que Software Engineer (React principalement).
Plus récemment, je viens de faire ce site : societhy .com en collaboration avec un ami développeur (React - Typescript)

Pendant le Master Entrepreneurs, j'ai co-organisé l'évènement NFT Paris à Station F (janvier 2022).

Je parle français, anglais et polonais.

Je cherche à travailler quelques heures par semaine en plus de mon CDI, sur mon temps libre, pour continuer à me former.
