Employment

    • Worked with a client based in Australia to build a businesses review app mixed with TikTok-like video features; currently live in the Play Store and used by thousands of users.
    • Developed and released the biggest live and future betting features with little to no handover for Tuttur, a top-five sports betting app in Turkey; currently live in the Play Store and used by thousands of users.
    • Joined the project after their main developer left and rescued it—took over an 80,000 LOC codebase, fixed several stability bugs, and added pending feature requests all without delaying the new release launch date.
