Portfolio

Over a short engagement I built real-time notifications over sockets (unread state, match and league invitations, new-subscriber events on the back end), user management for admins (roles, ban status with a reason, search and sorting, a guard against changing your own role), payment management with blockchain and account transactions, and a categories admin with image cropping and a separate game-rules module in the API.

For a year and a half I was one of the most active front-end developers and also reviewed and merged other developers’ work:

• Chat and threads: a rich-text editor with mentions, emoji, pasted images and drag-and-drop files; voice messages that work across browser, desktop and iOS; threads with badges, pagination and deep links from push notifications; infinite scroll with “jump to present”; search; group chats and DMs; turning a message into a task, event or note with its attachments.
• Boards and tasks: kanban with drag-and-drop and auto-scroll, backlog and archive, labels and filters, estimates, subtasks, personal boards updated in real time.
• Calendar, notes and files: reminders, all-day and recurring events, daylight-saving handling, checklists, a data room with public and private folders and permissions.
• Video calls: calls in spaces, projects and DMs, a ringtone that works in the background on iOS, external guests.
• Mobile and desktop: new navigation and redesigned screens, iPad and landscape support, Android and iOS builds and store accounts, desktop notifications, Do Not Disturb, deep links and signed builds for Windows and macOS.
