I work at the intersection of ERP security, SOC operations, and secure software delivery. My focus is turning security and audit requirements into practical Python tooling, repeatable controls, and useful evidence.

  • Senior Cybersecurity Engineer at SchutzOn, focused on multi-ERP security and compliance automation
  • Built Python-based audit automation that reduced review time by 85% within its measured project scope
  • Research interests: privileged access management, adaptive authentication, SIEM/PAM integration, and AI-assisted AppSec
  • Open to research and open-source collaboration in ERP security, DevSecOps, and privacy tooling

Selected open-source work

Project What it demonstrates Evidence
ERP Security Evidence Workbench Deterministic analysis and correlation of synthetic, ERP-neutral security evidence with evidence-linked JSON, HTML, and SARIF reports. v0.2.0rc1 (pre-release) · CI · CodeQL · MIT
Simple Vulnerability Scanner Audit-oriented CycloneDX/SPDX analysis with OSV enrichment, OpenVEX reconciliation, baselines, policy gates, and JSON, HTML, and SARIF reports. v0.3.0 · CI · CodeQL · Demo · MIT
Zero Trust Gateway Loopback-only lab demonstrating strict JWT/JWKS validation, key rotation, rate limits, audit events, and tested failure paths. v0.2.0 · CI · CodeQL · MIT
Metadata Scrubber Local-first CLI for removing and verifying metadata in images, PDFs, Office files, video, and optional audio. v0.2.0 · CI · Tests · MIT
DNS Lookup Tool Raw UDP/TCP DNS queries with trace mode, EDNS support, and structured JSON output. v0.3.5 · CI · Tests · MIT

Additional security prototypes and research projects are available in my repositories. Prototype repositories are labelled with their current status and limitations.

Focus areas

  • ERP security: SAP and Oracle security monitoring, access controls, audit evidence, and compliance automation
  • Security engineering: Python, secure automation, vulnerability analysis, privacy tooling, and defensive controls
  • SOC and DevSecOps: SIEM integration, threat detection, SBOM workflows, SAST, and security reporting
  • Applied AI: LLM-assisted analysis with human review, explicit limitations, and secure-by-default integrations

Open-source roadmap

  • Authorized Exposure Assessment Case Study — Planned. A permission-first, lab-scoped case study correlating DNS, port, Nmap, and TLS evidence into a reproducible external-exposure assessment.
  • Data Protection Case Study — Planned. An evidence-linked data-lifecycle case study connecting metadata sanitization, secret discovery, privacy checks, and removable-media monitoring without claiming to be a complete DLP or compliance platform.

These are independent portfolio research directions, not released capabilities or delivery commitments. Exposure testing will be limited to systems I own or am explicitly authorized to test; datasets will be synthetic or openly licensed.
