During April 2026, Spark contributed to the telegramdesktop/tdesktop repository by developing the Proxy Sharing Deep Link Enhancement. This feature replaced traditional t.me proxy share links with tg:// deep links, allowing users to share proxies directly through the Telegram app and improving the overall proxy sharing workflow. Spark implemented this enhancement using C++ and applied network programming principles to ensure seamless cross-app integration and maintainability. While the scope was focused on a single feature and did not involve bug fixes, the work demonstrated a clear understanding of software development practices and addressed a specific need for streamlined proxy sharing within Telegram.
