About me
I'm a second-year Computer Science & Entrepreneurship student at Reichman University with a GPA of 92, on a combined track that builds technical depth alongside product-oriented thinking. Before university I served as a Combat ICT Officer in the IDF Paratroopers Brigade, where I led a team of 23 and delivered 10+ end-to-end technology projects with Israel's top defense firms, from first requirement to operational deployment. During deployment I was the senior-ranking ICT officer in the brigade, keeping systems and connectivity up around the clock. Today I serve in the reserves as a Combat ICT Officer (Captain) in a commando unit, and I build AI and security tools: a permission layer for AI assistants, a credit-risk model you can see inside, and a news map for Asia. I am looking for a student developer or product role.

Things I'vebuilt
Three projects, each built end to end: an AI security layer, an explainable credit model and a news map. All code is public.
All code on GitHub01Project
Permissionguard
A permission layer between an AI assistant and its tools: every action is allowed, denied, or put to a human.
What it does
- 01Checks every file or shell action an assistant asks for against a YAML policy: allow, deny, or ask a human.
- 02Writes each decision to a hash-chained, tamper-evident audit log before the tool runs.
- 03Runs as an MCP server, so any MCP client gets the same policy, with approval through MCP elicitation.
- 04Ships a prompt-injection demo and a red-team test suite; attacks that still work are pinned as xfail tests.

- MCP

02Project
Glassbox
A credit-risk model you can see inside: every approve or decline comes with its reasons.
NoteStudent project on public data. The live demo runs a model trained on synthetic applicants, so its numbers are illustrative, never real customers. The results below come from the held-out test set of the public Home Credit data. The free server can take up to a minute to wake.
What it does
- 01Predicts the chance an applicant defaults with LightGBM, trained on public Home Credit data.
- 02Turns risk into approve or decline with a cost-based cut-off: approve only when expected profit is positive.
- 03Explains every decision with SHAP reason codes, computed live on each request.
- 04Replays the policy in a portfolio simulator and audits the outcome by gender and age.

03Project
Eastwire
English-language news from China, India, South Korea and Japan, on a map, with every source shown.
- China
- India
- South Korea
- Japan
NoteRuns on free hosting: the search and filter API sleeps when idle, so the first request after a quiet spell can take a while to wake up.
What it does
- 01Collects English-language news about four countries every hour, from sources whose terms allow it.
- 02Pins stories to cities by role: where they are about, where they are datelined, where the publisher sits.
- 03Shows every source and why it is allowed; a publisher that has not allowed reuse is simply not shown.
- 04Full-text search with phrases, exclusions and OR, plus six rule-based sector tags you can audit.
