Cybersecurity Engineer with hands-on experience in security assessment, penetration testing labs, secure software development and Zero Trust architecture. Experienced in vulnerability identification, attack scenario analysis, authentication and access-control review, risk assessment and security architecture. My final-year project combined Zero Trust, Machine Learning-based anomaly detection, cryptography, digital identity and secure infrastructure.

Strong interest in cybersecurity, AI security and evaluating security recommendations against recognized security standards.

FINAL-YEAR PROJECT - Zero Trust Architecture for eSIM/iSIM Contract Security at TUNISIE TELECOM (2026-02 – 2026-06)

• Designed a multi-microservice Zero Trust architecture for securing the eSIM/iSIM contract lifecycle.
• Developed a multi-dimensional risk scoring engine combining business rules and Machine Learning (Isolation Forest) for anomaly detection.
• Implemented Ed25519 digital signatures with HashiCorp Vault for secure key management.
• Implemented Merkle Tree anchoring on Ethereum Sepolia to provide tamper-resistant traceability.
• Integrated Schnorr P-256 Zero-Knowledge Proofs, W3C DID and Verifiable Credentials for decentralized authentication.
• Deployed and orchestrated 14 services using Docker Compose, including Keycloak, Redis, PostgreSQL, Kafka, Prometheus, Grafana and Nginx.
• Performed security and functional validation of the architecture and documented security controls, test results and findings.
• Analyzed risks and security scenarios and translated security requirements into technical controls.
• Presented the security architecture and technical decisions to an academic jury and industry stakeholders.

Cybersecurity Intern at Bravo Service (2025-06 – 2025-08)

• Designed and developed a secure digital-signature solution using Python, Flask, ECDSA and OpenSSL.
• Implemented and tested security-oriented functionalities and cryptographic mechanisms.
• Contributed to technical documentation and validation of the developed solution.

Security Audit Intern at SNDP Agil Energy (2024-06 – 2024-08)

• Conducted network and application security assessments.
• Identified security weaknesses and gaps and analyzed their potential impact.
• Documented findings and proposed recommendations aligned with security best practices.
