Customer-facing by trade. Systems-minded by training.

I am a computer science student at UNSW with five years in retail sales and a year in software support. I like work where clear communication and careful debugging matter equally.

About

Most of my working life has been on a shop floor: listening to what a customer actually needs, explaining the options without jargon, and fixing the problem when the first answer is wrong. That habit carries into software. I read the error, reproduce the failure, and keep going until the cause is clear.

At university I have worked in C, C++, TypeScript/JavaScript and Rust. Outside coursework I build small, complete systems — a service-desk application with a real database and audit trail, an evaluation harness that runs without a network, and a Rust asset register with an allow-list it enforces in code.

I am looking for a graduate role where I can keep learning from people who care about the details, and where explaining technical work to non-technical people is part of the job rather than an afterthought.

Selected projects

Small, complete systems with tests, documentation and a clear boundary around what they do. Each one links to its public repository.

01

Service-desk application

Relay Desk

A production-shaped IT service-desk ticketing app: strict TypeScript on Node, PostgreSQL with SQL migrations, role-based access, an append-only audit trail and an SLA clock computed from a documented policy.

Server-rendered HTML that works without JavaScript, a small explicit status machine, and tests that cover every status transition.

  • TypeScript
  • Node
  • PostgreSQL
  • Fastify

Evaluation harness

ai-eval-checker

An evaluation harness for IT ticket classification and reply drafting. It scores output against a committed, hand-labelled golden set and lets you read every failure individually.

A deterministic rules baseline runs offline with no key and no dependencies; a provider interface leaves room for a live model without changing the scoring path.

  • TypeScript
  • Zero dependencies
  • CI fixtures

GitHub

03

Network asset register

netregister

A small, honest asset register for one local network segment. It finds hosts with ARP, records them in SQLite, and answers the support question: what equipment do we have, and when was it last seen?

The scanner refuses any network outside its configured allow-list before sending a packet, and the CLI exports table, TSV or JSON.

  • Rust
  • SQLite
  • CLI

Let’s talk about work that needs both care and code.

The fastest way to reach me is email. I am based in Sydney and happy to talk about graduate software, support and operations roles.
