  • image of sixtimesnothing NodeJS Code Review & Enhancements $355.50 AUD

    “Guangyi helped us to implement a much needed security system for a complex NodeJS based API for a multiplayer game. His knowledge and code quality was consistently high. His help was instrumental to the project, as our team lacked sufficient knowledge about secure systems to execute the work ourselves. He also went out of his way to get the work done rapidly to assist in meeting our timelines which was greatly appreciated. The project was not completed due to rising costs caused by increasing complexity of the implementation. Guangyi helped us to explore a range of options and solutions, however we eventually came to the amicable agreement to close the project, and we moved the remainder of the work back in-house. We would like to offer our recommendation for Guangyi and wish him all the best of his future freelance work.”
