Projects
Selected things I've built (Full writeups coming soon):
Spring 2026Systems / Networking
Custom IP-TCP Stack & SSH-2
A userspace IP/TCP stack in Go (RFC 9293) with ICMP and distance-vector RIP routing, plus a from-scratch SSH-2 layer — Diffie-Hellman, AES-CTR, HMAC-SHA2. Drove interactive shells over a simulated network, validated by Wireshark.
Spring 2026Cryptography
Secure Voting Platform
A four-binary distributed voting system in C++/CryptoPP using ElGamal homomorphic encryption, NIZKPs via Fiat-Shamir, RSA blind signatures, and a quorum partial-decryption protocol — eliminating single points of trust.
2026Browser extension
Blockwork
Blocking like Clockwork™ — a Firefox extension for blocking distracting domains and keywords. Per-list proceed rules, history scrubbing, four curated default categories (distractions, telemetry, malicious, explicit).
2024 — presentPortfolio
nahum.work
The site you're reading. Built with Next.js, React, and TypeScript on top of Tailwind CSS, with anime.js powering the interaction layer.
Fall 2024Machine learning
Tumor Detection CNN
Fine-tuned a VGG-16 CNN for brain-tumor detection on MRI scans — 90% vs. a 63% human-radiologist baseline. Four-class classification across glioma, meningioma, pituitary, and no-tumor; LIME + saliency-map analysis.
2023Web app
Arithmatic
A timed arithmetic drill built around a 120-second session loop. Vanilla JavaScript, single-file static page.
