Project history
Development of an AI PR review tool assistant for analysing pull requests and producing structured, auditable review briefs. Designed to integrate with CI/CD pipelines, emphasising reliability, context grounding, and governance. Applied LLM tool-calling concepts to SDLC workflows including code review, security findings analysis, and test suggestion to reduce manual review effort and improve consistency in review outcomes.
Developed and operated a Security Operations Center (SOC) stack for a metering platform serving 500+ customers. Implemented and managed vulnerability management and incident response processes aligned with risk-based prioritization, leveraging image-based analysis, Falco rules, and Trivy scans. Automated incident handling and remediation workflows using SOAR tooling (TheHive, Cortex). Supported security assessments and continuous improvement of security controls across cloud and Kubernetes environments. Technologies: Azure, Cassandra, Prometheus, Grafana, Falco, Trivy, Packetbeat, Elastic Stack (SIEM), TheHive, Cortex, CrowdSec.
Automation and configuration of a Docker Swarm cluster on a TuringPi 2 board using Puppet. Developed a robust solution for managing containerized applications efficiently. Managed and orchestrated multiple nodes, ensuring seamless network connectivity and fault tolerance.
