DevOps Engineer • Solar Industry

Summerville

I've done door-to-door sales, admin, and DevOps. Now I build the systems the company runs on.

Self-taught in 2025, I automated my own admin role out of existence – then built the Job Adding System: 55 automations across 15 platforms, doing the work of two and a half to four people. I run it, and the Azure estate under it, end to end as code.

About

Sales floor to server room

I started in door-to-door solar sales, moved into operations and administration, and in 2025 taught myself to code. Within months I'd automated my own admin role out of existence – and kept going until the whole back office ran on the system I'd built.

Today I'm the company's DevOps engineer, owning its Azure estate end to end: provisioned as code with Terraform and Bicep, shipped through GitHub Actions, and secured zero-trust from the endpoint to the Cloudflare edge. The Job Adding System is documented to the point that a third-party team can be trained from it: a catalog with a flowchart per automation, a developer guide and a two-hour recorded walkthrough.

Alongside the products I run the group's cloud foundation, and I'm completing a Graduate Certificate in Computing at Charles Sturt University (cybersecurity & system design, High Distinction average) – the pathway to an IT Master's.

Job Adding System

Back-office automation platform · 55 automations · 15 platforms

A signed solar proposal in – a fully provisioned job out, across the document library, the job workbook, the CRM, the work board and the customer portal, in the time it takes to read the email. Then 46 scheduled jobs and 55 automations carry it through crew scheduling, compliance certificates, STC lodgement, invoicing and receipts with no hand on it.

  • Signature-verified webhooks feeding an idempotent, resumable queued worker
  • A staff web console under a strict CSP, single sign-on and a full audit trail
  • 4,300+ automated tests, CI gates for lint, types and dependency audit, infrastructure as code
  • Hardened VM: Key Vault secrets, sandboxed services, off-box security logging, nightly verified backups
  • Handover-ready: a catalog with a flowchart per automation, a developer guide and a two-hour walkthrough

Internal tool

RenewCompare

Energy-analysis tool for the sales team

Reads a customer's actual bills and shows, in plain dollars, which plan wins – including time-of-use, demand and battery-backed plans most comparators can't model. Built to product standard, it now runs as an internal tool rather than a public service.

  • Multi-service FastAPI backend with VNet-private Postgres on Azure Container Apps
  • AI bill parsing and hardened first-party auth – Argon2id with rotating refresh tokens
  • Half-hourly quantile price forecasts trained on 27 years of AEMO settlement data
  • A Rust optimiser that schedules home batteries in under a millisecond
FastAPI • PostgreSQL • Rust • React Native • Cloudflare

JMS web console

The staff face of the Job Adding System

Job 360 for any job across every system, a Data health page for the mirror, on-demand reports, live actions behind a confirm, a job editor with an audit trail, and a System module rendered from the automation catalog.

  • No build step, no framework: one static shell and native ES modules under a self-only CSP
  • Cloudflare Access, OIDC with PKCE, an allowlist in code and CSRF on every write
  • Every screen verified in light, dark and mobile with a Playwright harness

Infrastructure

Group cloud foundation

The whole Azure estate as code – Terraform and Bicep provisioning, GitHub Actions pipelines, Entra ID and Intune policy as code, secured zero-trust from endpoint to edge.

Experience

The road here

Dec 2025 – present

DevOps Engineer

Solar installation company

Own the Azure estate end to end – provisioned with Terraform and Bicep, shipped through GitHub Actions – and run identity and endpoint security as code: Entra ID, Intune, LAPS, Essential Eight. Built the Job Adding System that runs the back office, 55 automations across 15 platforms, and RenewCompare, the company's internal energy-analysis tool. Documented both for handover.

Jul 2022 – Dec 2025

Administration Manager

Solar installation company

Ran the back office for a high-volume solar installer – then taught myself Python in 2025 and automated the role out of existence. What began as Excel macros became a suite of scheduled tools running unattended, and led directly into the DevOps role.

Oct 2024 – Dec 2025

Reporter

Sydney community radio

Researched, wrote and voiced news bulletins – a sideline that keeps the writing sharp and the mic comfortable.

Mar 2021 – Apr 2022

Lead Generator – door-to-door solar

Solar installation company

Where it began: on doorsteps, working to daily targets. Opening cold conversations, handling objections and earning trust quickly – learning the product, the customers and the business from the ground up.
