Welcome to my portfolio, I will introduce myself in detail later.
You are welcome to view my projects.
PROJECT 1#
BI-BIKE
Ride indoors and outdoors
Bicycles for life in the city
2.1 meters
length in close position
17 kilograms
total weight
The integrated rear rack doubles as a foldable indoor bike trainer, seamlessly converting for stationary riding at home. It lets you train wherever you are, without the hassle of transporting or purchasing separate gear.

between different modes
PROJECT 2#
Physiotherapy practice app
USING AI TO TRACK IMPROVEMENT
15
Prototype testing users
94%
user satisfaction
ZUZU is a personalized physiotherapy app designed to enhance recovery through smart guidance and real-time progress tracking. The app allows therapists to tailor and update exercise plans remotely, while users receive clear, step-by-step instructions and explanations throughout their sessions. An integrated AI system monitors performance, evaluates improvement, and provides meaningful feedback to both users and therapists — making rehabilitation more adaptive, data-driven, and user-friendly.
PROJECT 3#
ROADRONE
5 km/h
work speed
50%
Less impact on traffic
Roadrone is a cable-connected road-painting drone system attached to a pickup truck. Two drones operate on either side, drawing paint from the truck and marking lanes up to 7 meters away. The system can add more drones to widen coverage. Painting occurs while the truck moves at 3–8 km/h, minimizing lane closures and reducing traffic disruptions by up to 40-60% compared to traditional methods.
ROADRONE
Roadrone features low-maintenance components designed for durability in harsh road environments. The cable connection ensures a stable power and paint supply, reducing the risk of operational interruptions. Its compact size allows easy transport and quick deployment alongside the pickup truck. The system’s flexibility enables operators to adapt painting patterns on-the-fly, optimizing work schedules and reducing downtime.
PROJECT 4#
SMART CANE
90%
Less cost than a similar product
50
milliseconds warning time
This smart walking cane uses an ultrasonic sensor connected to an Arduino board to detect obstacles above ground level that could hit the user’s head, such as branches. When an obstacle is detected, it instantly activates a vibration motor to alert the user, improving safety by providing early warning of overhead hazards.

Other things I like to do
PROJECT 5#
RAPHAEL - Smart System for Rescuing Hikers
Raphael is an intelligent rescue system designed for solo hikers and athletes. It includes a smart watch with sensors that detect injuries and automatically activate the core device, Raphael. Using AI, GPS, satellite communication, and built-in lighting, the system analyzes the user's condition and location, and sends an emergency signal for immediate rescue—even when there's no cellular coverage.
