Systems I've built

Private client project · In production

Salon Appointment System

A full-stack booking and salon-management system built for a real client. Customers book without an account, verify their phone with a one-time code, and every request is approved by the assigned stylist. Confirmations, reminders and a cryptographically signed manage link are handled automatically.

Distributed systems02

Order-Saga

Order processing across 5 microservices using the Choreography Saga pattern. Services coordinate purely through Kafka events, with automatic compensation when a step fails.

Emergency-Alert-System

Pub-sub alert broadcasting over STOMP: a Java server switchable between thread-per-client and a non-blocking NIO reactor, paired with a C++11 Boost ASIO client.

About

Building software , Sharing knowledge , Bringing people together.

I’m a Computer Science student at Ben-Gurion University of the Negev, graduating in 2028. I enjoy taking an idea from its first sketch to working software—and understanding the decisions that make it reliable.

My work spans a production booking platform for a paying business, event-driven microservices, and AI applications built around retrieval and autonomous agents. I’m especially interested in backend engineering and distributed systems: how services communicate, handle failures, and stay consistent.
