Welcome to my portfolio, I will introduce myself in detail later.
You are welcome to view my projects.
PROJECT #1
Graduation Project with Highest Distinction
MOMENTUM*
Outdoor Active Learning Space
נוע תנוע*
Traditional school environments force children into a severe sedentary lifestyle, keeping them statically seated for most of the day. This prolonged lack of movement negatively impacts both their physical health and cognitive development. The proposed solution is an outdoor active learning structure that completely removes the physical barriers of conventional desks and chairs. Instead of forcing exercise, this architectural space naturally encourages dynamic movement—such as climbing and crawling—making physical activity an integral and structured part of the educational experience.
PROJECT #1
Designed for movement
Adapting to every educational need
The Cave
Located beneath the main structure, this shaded space is designed for individual processing and sensory regulation. It provides an intimate, quiet environment where students can focus and recharge away from the active exterior.
The Campfire
The upper Ipe wood deck serves as the central gathering space for group discussions and theoretical learning. It allows teachers to introduce new topics while students engage in dynamic, natural seating postures rather than being confined to traditional chairs.

The Hub
Centered around a living tree, this collaborative area features sensory wooden shelves and a pedagogical documentation net. It functions as a dynamic space where students can explore natural materials, share ideas, and actively exhibit their projects to their peers.
PROJECT #2
BI-BIKE
Ride indoors and outdoors
PROJECT #2
Easy transition

PROJECT #3
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 #4
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 #5
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 #6
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.
