The star rating is calculated by averaging the reviews provided by all clients the talent has worked with for a significant amount of time.

If such data is not available, the star rating is calculated from the fraction of work sessions approved by their past clients versus the total tracked by the talent.

If such data is not available, the star rating defaults to the interview rating of the talent at the time of the vetting process.

Other data including reviews from interviews are available on the talents’ profiles but do not influence their star rating, though they do influence their position in the search results.

Profile Summary
I’m a software developer with skills in JavaScript (React, React Native, Next.JS, and Node) and Golang. I have been working as a remote software developer and I have been developing applications professionally. Therefore, I'm not just a developer but also an open-minded, creative collaborator who is not afraid of working on tough problems in an extremely fast-paced environment. I'm comfortable taking up entire projects and working from scratch to deliver solutions that meet the desired goals.
