Perth, Western Australia · software engineer & ICT business analyst
I write the spec. Then I ship it.
I'm Vy Nguyen — a Perth software engineer (Master of Computer Science) shipping full-stack data products: FastAPI, React, PostgreSQL, tests on every merge. The twist: I'm also ECBA-certified in business analysis. Most teams need two people for what I do — one to work out what the business needs, one to build it properly. I'm both.

About
I sit where the business meets the build.
My route here runs through three countries: a computer science degree in Ho Chi Minh City, a cybersecurity diploma in Canada, and a Master of Computer Science at Edith Cowan University here in Perth. Along the way I noticed that projects rarely fail in the code — they fail in the gap between what the business meant and what the team heard.
So I made that gap my specialty — from both sides. At Spirited Thinking I turned a client's idea for an AI image-classification system into functional specs and test cases the delivery team built against. At FPT I automated SAP reporting in ABAP after sitting with the people who actually ran the reports. In 2026 I put a credential behind each half: the ECBA from the IIBA on top of my Master of Computer Science — then shipped a portfolio the way real teams ship, with requirements catalogues, sprint backlogs, test suites and CI.
That's the profile: an engineer who writes the requirements, and an analyst who ships the build. Developers get specs they don't have to translate; the business gets software it can trace back to what it actually asked for.
Now: joining Viewport XR (immersive tech, Perth) from August 2026 · completing an ACS Professional Year in IT · open to freelance data & simulation builds
Full-stack, end to end
FastAPI, React/TypeScript, PostgreSQL, Docker, GitHub Actions — the WA Mining app runs the whole stack, with CI proving it on every merge.
Evidence over claims
Every skill on this site traces to an artefact you can open — an API, a test suite, a data dictionary, a backlog.
Requirements-literate
ECBA-certified. I elicit, document and test against requirements — so what ships matches what the business meant.
Three languages
English, Vietnamese and Japanese — useful in stakeholder rooms, invaluable in messy requirement conversations.
Featured work
Projects you can open, not just read about.
Every case study ships with its working parts — the code, the requirements, the pipelines, the backlog. Filter by the kind of work you're hiring for.
WA Mining Portfolio
Raw CSV → governed, tested application.
A Western Australian government mining dataset — 421 sites across 356 projects — shipped as a tested FastAPI + React application with Docker and CI, and built on real BA discovery: a requirements catalogue, a 19-field data dictionary, a five-step SQL pipeline and a two-page Power BI dashboard.
- Live app
- 421 sites
- 356 projects
- 3 sprints
- 41 issues
Shift Supervisor Sim
The same mining data — spatial, 3D, walkable.
A deliberately small Unity/C# prototype answering "what's the status of my sites?" spatially instead of in charts — now evolving into a simulation-focused showcase, with v2 scoped by a validated requirements discovery before a single scene is built.
- Unity · C#
- v1 shipped
- v2 discovery ✓
Mental Health Treatment Gap
BA discovery and governance, done properly.
A hybrid BA/data case study on Western Australia's mental-health treatment gap: full discovery plus a formal governance pack — business case, project charter, stakeholder and risk registers — then Sprint 1 delivered with two verified national datasets covering all 31 Primary Health Networks.
- 73,132 records
- 31 PHNs
- Sprint 1 of 5
Person Re-Identification
A PyTorch re-implementation, measured honestly.
PCB (Part-based Convolutional Baseline) for person re-identification, built as a modular training pipeline and evaluated on benchmark datasets — 92.9% Rank-1 and 78.5% mAP on Market1501, with the experimental setup documented so the numbers can be checked.
- 92.87% Rank-1
- 78.54% mAP
- Dockerised

Got a build in mind?
I'm in Perth, joining Viewport XR in August, and taking freelance data-product and simulation work. Bring me a messy problem — I'll bring back a spec, a build, and the tests that prove it.
