Embedded Hardware Developer in Zagreb, Croatia

Member since August 24, 2015
For the last eleven years, Igor has been working as an embedded engineer and web programmer (both front- and back-end). Beside his main job, he likes to take interesting web and hardware related side projects (usually in cooperation with local artists, theaters, and maker spaces). He loves a challenge and enjoys making software and hardware visions come to life.
Igor is now available for hire
