It is necessary to transfer all information in Viber with chats and files from iPhone 13 to Samsung S26 Ultra.

Develop a mobile application (iOS and Android) that will automatically import health and physical activity data from smartwatches (Garmin, Huawei, Apple Watch, Samsung, Fitbit, Polar, etc.) through official integrations (Apple HealthKit, Google Health Connect, as well as manufacturers' APIs where possible). The application must: automatically synchronize data with our server database; store the complete user history; send data for analysis to ChatGPT; allow ChatGPT to analyze long-term trends and provide personalized recommendations (sleep, recovery, workouts, VO₂ Max, HRV, health metrics, etc.). At the first stage, it is necessary to determine the optimal technical solution for the automatic import of data from various smartwatch ecosystems.

Development of Telegram Mini App "SlashX" About the project A modern Telegram Mini App called SlashX needs to be developed. The main idea is a gaming platform within Telegram, where the user completes tasks, earns in-game currency, levels up, participates in rankings and tournaments, and invites friends. This includes several links to casinos where the game directs the player. It is important to create not just a Telegram bot, but a beautiful Mini App with modern design and smooth animations. Interface style: dark theme; bright neon colors (purple + lime); modern gaming UI; mobile game level design. Main screens 1. Home Should display: user avatar; nickname; level; XP progress; balance of in-game currency; Daily Bonus; quick access buttons; seasonal progress (Season Pass); latest bonuses; large navigation buttons. 2. Tasks Types of tasks: subscribe to a Telegram channel; view news; visit a partner; complete special missions; daily tasks; achievements. After completion, the user receives in-game currency. 3. Casinos (partners) A list of partners in the form of beautiful cards. Each card should contain: logo; rating; bonus; "Activate Bonus" button. After clicking, a partner link opens. 4. Friends Referral system. Features: referral link; "Invite" button; friends list; number of active friends; earned from referrals; statistics. 5. Tournaments Needs: leaderboard; user's position; prize pool; timer; seasonal tournaments. 6. Profile Should contain: avatar; level; XP; balance; transaction history; promo codes; settings; support. In-game currency The project uses its own currency. With it, the user: unlocks bonuses; plays mini-games; receives rewards; participates in internal mechanics. Referral system The user receives a personal link. For each new user, they receive a bonus. Protection against manipulation is necessary. Admin panel Should allow: adding partners; changing bonuses; creating new tasks; managing users; viewing statistics; launching newsletters; creating promo codes; changing seasons; managing tournaments. Push notifications The ability to send messages to all users via the Telegram bot is needed. For example: new bonuses; new partners; promotions; tournaments; seasonal events.

We are developing a photo editor with AI features similar to FaceApp. The design and layout are entirely on our side — you are required to provide the backend and integrate neural network functionality. What needs to be done: • Backend for photo processing (uploading, processing, delivering results) • Integration of AI filters: age modification (aging/rejuvenation), gender change, smile, hairstyles, makeup, backgrounds, background replacement • Image processing queue and optimization of response speed • Storage and management of user photos (considering privacy) • Integration of a payment system and subscription model (in-app purchases), likely with web view to bypass Apple's 30% fee. • API for communication with the frontend (we will handle the frontend ourselves) Requirements: • Experience in developing iOS applications (Swift) • Experience with ML/CV — own models or integration of ready-made ones (Stable Diffusion, GAN models, third-party AI APIs) • Understanding of image processing on the backend • Portfolio with similar projects is welcome What is important: The quality of the result must not be inferior to FaceApp — the content and functionality should be at the same level. If you have ideas on how to make something better or more interesting — we are open to suggestions, but this is not a priority. The main thing is a stable working product.
