Itamar Nosrat

Small projects from a quiet corner of the internet.

I'm a third-year computer science student at HIT and a fraud risk analyst at a credit-card company, drawn to cybersecurity and AI. Everything here started as a real question I wanted to answer — this site is where those answers end up, starting small and growing over time.

Projects

What I'm building

This list is short on purpose — it grows when something is real enough to share.

Fraud Watch

itamarn.com/fraudwatch

Live

Work a shift as a credit-card fraud analyst.

An arcade-style simulation where you review real-looking transaction files under a ticking clock, weigh the risk signals, and decide: approve or block. One wrong call costs you.

  • Risk-signal gameplay. Every case file carries real fraud indicators — stolen-card reports, foreign locations, device history, customer profile — that you combine into one decision under time pressure.
  • Guided tutorial. A five-minute guided mode teaches how analysts actually weigh signals before the timer starts working against you.
  • Shift reports. Every shift ends with accuracy stats, streak records, and a PDF export of the cases you got wrong.

The Fitness App

Working title · coming soon

In development

Track your training and food — and actually learn from it.

A nutrition and fitness app that logs workouts and meals, then turns the numbers into practical suggestions. It's in early development — built the same way Fraud Watch was: around a real need, with Claude as a pair programmer.

  • One log for everything. Workouts and meals in one place, designed for quick daily logging instead of endless forms.
  • Practical suggestions. Designed to read your own history and point at specific, small improvements — not generic fitness advice.
  • Early and honest. No release date yet. This card and page will fill in as the app becomes real.

About

Studying the field, building along the way

I'm in my third year of computer science at HIT — Holon Institute of Technology — and I work as a fraud risk analyst at a credit-card company. Cybersecurity and AI are the two threads I keep pulling on, and the projects here are where they meet: small, finished things instead of half-started big ones.

Right now I'm building the next project: a nutrition and fitness app. Early days — it'll show up here when it's real.
