Develop a solution that enables users to manage their personal finances using voice assistants and AI. The platform should offer personalized financial advice based on user data analysis, assist with budget planning, track expenses, and suggest real-time investment opportunities. Pay special attention to integration with banks and financial services, ensuring high data security.

Create an AI system for automatic analysis of customer feedback from various sources (social media, chats, website reviews). The system's goal is to identify key complaints, suggestions, and customer sentiments, generating real-time reports for managers. The AI must be capable of distinguishing sentiment tones (positive, neutral, and negative) and providing specific recommendations for service improvements.

Develop a next-generation multi-factor authentication (MFA) system that considers not only standard parameters (password + SMS code) but also behavioral factors (e.g., typing speed, mouse usage patterns, location). The system should analyze these parameters in real-time, enhancing security by identifying suspicious behavior.

Create a real-time air quality monitoring platform for cities. The platform should use data from sensors installed across the city, along with meteorological data and social media sources. Your task is to develop a solution that analyzes and visualizes the data, provides AI-based forecasts, and offers recommendations to city services for pollution reduction (e.g., rerouting traffic or limiting industrial emissions).
