At Boehringer Ingelheim, I maintained DAST/SAST analysis scripts and integrated vulnerability management tooling through APIs in a pharmaceutical CISOC environment. I also reviewed security controls and analyzed risk across corporate projects.

At Capgemini, I monitored SIEM alerts, analyzed logs, and supported incident triage, classification, and escalation as a Security Analyst Intern.

At Nestlé, I analyzed payment records to identify fraud and anomalies, while monitoring KPIs and preparing reports to support decision-making.

I'm currently developing a self-hosted sports planning and tracking platform, using a contract-first REST API, separated database roles, and automated tests. I also taught mathematics, physics, and cybersecurity, translating technical concepts for non-expert audiences.
