Custom Browser Using Chromium Open-source Browser

https://www.youtube.com/watch?v=wKHbwY5_RWY
The company wanted to build its own web browser with unique features but didn't know where to start. I suggested using Chromium's open-source browser because it provides a wide variety of features and doesn't need other third-party libraries to achieve their goals. Even though the Chromium codebase is massive, I dove in quickly to assemble the necessary parts and added essential features at the same time.
