What I do

Three areas I work across, every single week

Cybersecurity

SOC monitoring, endpoint protection, network security, and incident response. Currently securing 1,500+ endpoints at Family Bank.

Software development

Full-stack web development using Python, Django, React, and Next.js. I build secure, practical applications.

IT support

Technical support, infrastructure management, and system administration in enterprise banking environments.

How I work

A typical incident, start to finish

01

Monitor and detect

Watch 1,500+ endpoints across the network for anomalies, alerts, and threat signatures in real time.

02

Investigate and triage

Pull logs, correlate events, and determine whether an alert is noise or a genuine incident that needs escalation.

03

Contain and respond

Isolate affected systems, apply fixes, and coordinate with the wider team to stop an incident from spreading.

04

Document and improve

Write up the incident, update detection rules, and feed lessons back into the security posture.
