Software development

Full-stack web development with Python, Django, Next.js and TypeScript. I recently delivered a production ecommerce site for a client.

How I work

A typical incident, start to finish

01

Triage

Review the alert, decide how serious it is, and escalate high-priority incidents within SLA.

02

Investigate

Dig into logs and system data to find the root cause.

03

Contain and recover

Stop the problem spreading, fix the cause and restore normal service.

04

Document and follow up

Record the incident and the follow-up actions so management and auditors can review them.
