- Conducted secure code reviews and vulnerability assessments on Java/Spring Boot microservices, identifying and mitigating risks aligned with OWASP Top 10 (e.g., injection, XSS, broken access control)
- Performed application security testing of REST APIs, analysing authentication and authorisation flows (OAuth 2.0, JWT) to detect issues such as broken object-level authorisation (BOLA) and excessive data exposure
- Identified and remediated vulnerabilities through static analysis and manual review, reducing risks related to SQL injection, insecure deserialization, and sensitive data leakage
- Supported security testing and validation activities, including reviewing API endpoints, input validation logic, and access control enforcement mechanisms
- Applied encryption and secure data handling practices (TLS/SSL, AES), ensuring protection of sensitive data in line with GDPR requirements
- Developed Python scripts to assist in automated vulnerability scanning, dependency checking, and security monitoring, improving efficiency of security operations
- Collaborated with cross-functional teams to implement secure SDLC (shift-left security) practices, ensuring vulnerabilities are identified early in development
- Produced structured security documentation and vulnerability reports, outlining risks, impact, and remediation strategies
