Osama Altamar

Cybersecurity M.Sc. student at Saarland University with interests in security research, AI security, privacy-preserving systems, formal methods, and software engineering.

📍 Saarbrücken, Germany · Luxembourg
Languages: Arabic (native) · German (C1 / DSH-2) · English (professional)

I work at the intersection of security engineering, research, and software development. Public repositories below are the projects visitors can inspect; private coursework and internal tools are kept off this page.


🛡️ Cybersecurity & AI Security

  • CyberMirror — Local-first OSINT self-audit platform for analysing a public digital footprint.
  • Private Set Intersection Demo — Educational implementation of Private Set Intersection / Private Set Membership for privacy-preserving computation. Not production-ready cryptography.
  • Side-Channel Timing Attack Demo — Educational TCP timing side-channel lab using naive byte-by-byte password comparison.
  • AI-agent security — Policy enforcement and monitoring for AI agents (private prototype; not linked here).

Related professional work includes security architecture for a family-oriented network protection platform and browser-extension security analysis.


🔬 Research & Formal Methods

  • SoK Research Dashboard — Collaborative Systematization of Knowledge research dashboard.
  • Reactive synthesis lab — Experimentation with LTL, TLSF, controller synthesis, and related tooling (private research workspace).

💻 Software Engineering

  • codeforces-daily — Automated structure for solving and testing Codeforces problems, organized and CI-ready.
  • Books management system — Full-stack application with FastAPI, SAPUI5, and MongoDB (private).

Background also includes enterprise full-stack development (Java, Spring Boot, Angular, TypeScript) and test automation with Playwright, BDD/Gherkin, and Jenkins.


🎓 Academic / Learning

M.Sc. Cybersecurity, Saarland University (2025–present), following a B.Sc. in Cybersecurity at the same university. Bachelor thesis: Dynamic Analysis of Browser Extensions (CISPA-related research assistant work).

Public learning artifacts are limited to selected labs and demos. Course assignments remain private.
