At Bitski, I have been responsible with building and maintaining the user application for displaying and authorizing blockchain transactions between all of our client devices, on both iOS and web.
My responsibilities have entailed:
Implementing Figma designs for our wallet and signer using Svelte
Building features and maintaining services and operations
Integrating with third-party apps and developers
In addition, I delivered the implementation of wallet.bitski.com - our web wallet - and maintained it for sometime before transitioning to building a fuller featured experience via our Chrome Browser Extension.
To experience the extension, you can follow the install link at bitski.com.
