Agentic Era Hackathon
The Agentic Era Hackathon in Helsinki, organized by the Aalto AI team at Aalto University in collaboration with Wave Ventures, brings together builders to explore the next generation of AI systems powered by autonomous agents. At the hackathon, our team developed a web application that uses AI agents to manage and operate fitness studios through a unified interface. The platform enables studio owners to control and automate key operations such as class scheduling, instructor and resource management, financial calculations, and operational planning. By leveraging agent-based workflows, the system can coordinate tasks, optimize studio resources, and assist with decision-making, demonstrating how AI agents can streamline complex real-world business operations in the fitness industry.

Junction 2025
At Junction 2025 in Helsinki, our team participated in the Wolt Challenge by building an AI-powered prototype of a next-generation food delivery platform. We developed a web app inspired by Wolt’s interface, enhanced with several AI-driven features. Users can upload food photos to instantly find matching dishes using vision-based dish recognition, automatically generate ingredient shopping lists from selected meals, and discover food through an “OnlyFood” TikTok-style swipe feed powered by embeddings and AI-generated content. The platform also includes calendar-aware meal ordering, AI-planned event catering, and a gamified delivery ETA minigame that rewards users for predicting arrival times. The project explores how AI and intelligent interfaces can make food discovery, ordering, and planning more personalized, automated, and interactive.

Undercover game
The Undercover game clone is a simple mobile project built with Flutter. The goal of the project was to learn how Flutter works in practice, explore its development workflow, and gain hands-on experience with cross-platform mobile app development. The app recreates the core mechanics of the popular party game Undercover, focusing on implementing the basic gameplay and user interface. The project primarily served as a learning exercise, helping to understand Flutter’s UI framework, state management basics, and the overall process of building and running a mobile application.
