Web Extensions Developer in Irvine, CA, United States

Member since February 14, 2017
Yasir's been developing in JavaScript for a decade while using the latest ES6+ standards in all his current work. He is an expert front-end developer especially with React and Redux and is a growing star with React-Native. He also uses JS for much more, such as cross-platform desktop apps (Electron) and cross-browser extensions leveraging native APIs on Windows (WinAPI/COM), macOS (Carbon, Core Foundation, Cocoa), and *nix (X11/XCB, GTK+/GDK).
Yasir is now available for hire




Irvine, CA, United States



Preferred Environment

Windows 10, Git/GitHub, VSCode, Node 7+

The most amazing...

...thing I've coded was a cross-platform screenshot tool using JavaScript FFI to tap platform APIs.

  • NativeShot (Development)

    A Firefox add-on to take a screenshot of multi-monitor setups.

    1) Uses js-ctypes (FFI) to tap into C/C++/Objective-C platform APIs to access platform global hotkey registration and screenshot bitmaps. (WinAPI, Carbon, CoreFoundation, Cocoa, X11/XCB.)
    2) Uses React (with setState state management) for the dashboard GUI and canvas graphic editor.
    3) Uses REST APIs of Google Drive, Dropbox, Imgur, Twitter, and Facebook for screenshot cloud upload options.

  • jscFileWatcher (Development)

    A cross-platform file directory watcher module in JavaScript.

    1) Uses js-ctypes (FFI) to tap into platform APIs to watch file directories.

    2) Abstracted platform nuances from consuming developers it into a git submodule.

    3) Heavy lifting is done off the main thread in a WebWorker.

    4) Platform details:
    + Windows - Uses ReadDirectoryChangesW with the completion routine async approach.

    + macOS - Uses FSEvents 10.7+ design. Considered but decided against: kevent64, kevent.

    + Unix-based/GTK+ - Uses inotify if available, otherwise it falls back to GTK's GioFileMonitor. GTK is guaranteed as jscFileWatcher is designed for Firefox, a GTK+ application. Considered but decided against: kqueue, FEN (Solaris), kevent (FreeBSD).

    + Android - inotify (inode notify).

  • Trigger (Development)

    A cross-browser extension using native binaries to enable the user to tie browser Userscripts to global platform hotkeys.

    1) Uses Redux, React, and React Router v3 for GUI.
    2) Uses C, C++, and Objective-C for the binaries.
    3) Communication between extension and binary is done via the Native Messaging feature of the WebExtensions API.
    4) Platform specifics:
    • Unix-based: Uses XCB main even loop and xcb_grab_key, which is thread safe version of X11's XGrabKey.
    • macOS: Binary not yet released. Uses Carbon's RegisterEventHotKey as Apple has not yet provided a suitable replacement in Cocoa. However, Cocoa is used to run the main application event loop.
    • Windows: Instead of using WinAPI's RegisterHotKey a low-level keyboard hook (SetWindowsHookEx) was used. This is due to the former being keyboard manufacturer dependent for some special keys (media keys and so on).
