Practical work across Telegram bot development, crypto payment workflows, and VPS deployment. This included bot logic, membership flows, payment-related integration, deployment setup, and troubleshooting of production issues involving Docker-based services and server configuration. The focus was building reliable systems that connect messaging, automation, and payment handling in real-use environments.

Built a Telegram Mini App quiz system for weekly vocabulary review, designed to work with a public English-learning channel. The mini app loads quiz data by week, supports normalized week-based routing such as week001, reads start parameters from Telegram and URL query values, and opens the related channel directly from inside the app when needed. Main features include: - week-based quiz loading - support for normalized IDs such as week001, week002, etc. - Telegram WebApp integration - support for Telegram start parameters - progress bar and per-question flow - final score view - wrong-answer review section - restart quiz flow - direct channel open button - fallback “Quiz Not Found” screen when requested quiz data does not exist The UI was designed as a lightweight mobile-first experience for Telegram users, focused on fast interaction, simple navigation, and practical review after finishing the quiz.
