Work Experience

  • 04/2021 - 11/2024, SkyTech LLC

    • Senior iOS Developer. iOS Team Lead
      I've worked on two apps:
      1. Stacle - B2B secure messenger with audio/video calls and group chats. My work was consisted of:
      - splitting the app into modules (UI, Network, Login&SignUp etc)
      - transition of the app from old backend to new backend (I've had to restore some old functionality using new APIs and also implement some new logic)
      - complete rewriting of Login & SignUp module UI using SwiftUI
      - code refactoring

      2. Grapherex - secure messenger with crypto wallet module. I've implemented new functionalities and fixed bugs in crypto wallet module.
      - wallet redesign
      - migrating to firebase auth
      - firebase remote config integration
      - app localisation
      - implementation of non-custodial wallet (Fireblocks API)
      - bug fixes and new features for messenger and wallet integration
