Nikola Stojiljkovic
Verified Expert in Engineering
Algorithms Developer
As a computer science major, Nikola has worked in companies such as Google, Microsoft, GSA Capital, and a few startups—developing algorithms to solve large scale problems. He is more of a generalist, though he loves the detail and has a deep understanding development projects. He loves to build systems and to come up with solutions for challenging tasks. He considers it a bonus if projects include problems that haven't been solved before.
