From frontline analyst to security engineer

I've spent my career building security operations that actually work — from tuning SIEM alerts at a managed security provider, to engineering automation pipelines that power SecOps at scale.

Career Journey

Senior Security Engineer
Personio
Sept 2023 – Present

Building SecOps services end-to-end: log pipelines into SIEM, SOAR automations with AI enrichment, ISO 27001 controls implementation, and mentoring SOC analysts.

Advanced Security Engineer
Benevolent AI
Jul 2022 – Sept 2023

Secured Cyber Essentials Plus, automated asset reporting in Python, migrated applications to SSO, and streamlined alert investigation workflows.

Security Operations Engineer
Sky Bet
Feb 2021 – Jul 2022

Built MITRE ATT&CK-mapped detections, ensured PCI/SOX compliance, and implemented cloud security monitoring to catch out-of-guardrail deployments.

Security Operations Analyst
Sky Bet
Feb 2019 – Feb 2021

SIEM monitoring, PCI ASV scanning with Qualys, vulnerability reporting, and tool capability analysis to improve SOC operations.

Junior Security Analyst
Secure Data (now Orange CyberDefence)
Dec 2017 – Jan 2019

Frontline SOC: SIEM alert analysis, false-positive tuning, daily threat hunting on customer environments, and investigation playbook documentation.

How I can help your team

Practical security engineering and consulting for startups and mid-market teams that need expert guidance without enterprise overhead.

SOC Design & Optimisation

Design or overhaul your Security Operations Centre — from detection engineering and log pipelines to analyst workflows and sprint planning. Built on real experience running SecOps at MSSP and internal teams.

Incident Detection & Response

Build detection use cases mapped to MITRE ATT&CK that reflect your actual threat landscape — with containment, eradication, and recovery playbooks to match. Includes false-positive reduction and alert quality improvement.

SIEM Engineering

Log pipeline design, ingestion tuning, and detection rule management across Splunk and Datadog. I'll help you cut through the noise — standardising event formats, reducing false positives, and making your SIEM actually useful.

SOAR & Security Automation

Implement and extend SOAR platforms (Tines and others) with custom Python automations for incident response, alert triage, bug bounty triage, and asset reporting — reducing manual toil across your security team.

AI-Augmented Security Operations

Bring AI into your SecOps workflows — from LLM-powered alert enrichment and triage to AI-assisted threat summarisation. Practical, production-tested approaches that reduce analyst workload without replacing human judgement.

ISO 27001 & Cyber Essentials

Implement security controls, gather evidence, and prepare your team for ISO 27001 and Cyber Essentials Plus certification. Hands-on experience taking organisations through both — not just gap analysis, but doing the work.

Cloud Security Operations

Security monitoring and guardrail policies for AWS and GCP environments — alerting on out-of-policy deployments, implementing cloud-native detection, and integrating cloud logs into your SIEM pipeline.

Vulnerability Management

Stand up a structured vulnerability programme using Qualys and similar tooling — regular scanning, risk-prioritised reporting for engineering teams, and PCI ASV compliance. I'll help you move from reactive patching to proactive exposure management.

Threat Intelligence Integration

Operationalise threat intelligence — IOC-driven hunting, integrating feeds into detection pipelines, and building processes that give analysts context rather than noise. Informed by research presented at BlackHat Europe 2018.
