Data • Analytics • Supply Chain

Nga Doan

I work at the intersection of data, operations, and business performance, analysing how systems perform in practice and identifying where improvements can be made. With a background across agriculture and finance, I focus on using data to improve processes, support better decisions, and create practical impact in real-world environments. I take a structured, quality-focused approach and aim to deliver results that are both reliable and practical.

About

Background and direction

I completed a Master of Business Analytics, specialising in Supply Chain Management, at the University of Auckland, focusing on data-driven decision-making and operational improvement.

It has shaped much of my journey — from stepping beyond Vietnam to working across farms and operations in Australia and New Zealand, from finance to agriculture and supply chain, and more recently, to rebuilding legacy ETL workflows in Microsoft Fabric.

I am particularly interested in how data can improve operational performance, reduce inefficiencies, and support better decisions in real-world environments.

Work Experience

Professional and real-world experience

My resume doesn’t tell the full story.

From 2019 to 2024, I worked across farms, nurseries, and processing facilities in Australia and New Zealand under the Work and Holiday Visa scheme, adapting quickly to different operational environments, production systems, and team dynamics.

During this time, I collaborated with multicultural teams, completed horticulture certificate study alongside full-time work, travelled around 1,000 km a week between Bundaberg and Brisbane, and built strong endurance through physically demanding seasonal work.

Over two years, I grafted around 100,000 macadamia trees, improving to up to 500 trees a day — roughly 3× typical beginner productivity through continuous improvement of technique and workflow. These experiences shaped my work ethic and strengthened my understanding of how consistency, teamwork, and incremental process improvements influence productivity in large-scale operations. They also developed my resilience, agility, and persistence.

These experiences continue to shape how I approach operational problems, data quality, and improvement work today.

Beyond Work

A little more about me

I find clarity in movement — especially in places like trains, where everything is in motion, yet feels stable. It’s often where my thoughts become the most focused and clear.

Being close to nature is how I reset. I enjoy walking through forests, noticing small details — flowers, plants, even the quiet presence of moss. Looking up through the trees, watching light pass through the leaves, is something I never get tired of.

I also find comfort in simple, grounding routines. Cooking for someone I care about feels like a form of therapy, and cleaning — especially when I feel stuck — helps me reset and clear my mind.

I enjoy working with my hands — gardening and handcrafts give me a sense of connection, where I can feel the process, create something tangible, and express creativity in a quiet way.

Another thing I enjoy is film photography. I have a deep appreciation for my old film camera — an Asahi Pentax K1000, much older than me. With film, the experience matters more than the outcome. You take each photo, then wait until the roll is finished to see the result. I don’t try to be technical — I don’t focus on ISO, aperture, or settings. Every photo I take is based on feeling, a moment from my own journey.

There’s something meaningful in not knowing exactly what you will get. Sometimes the photos turn out beautifully, sometimes they don’t — but that uncertainty is part of what I enjoy. Even when people ask how I took a particular shot, I often don’t have a precise answer. It’s simply how I experienced that moment, and that’s what I value most about film photography.

I enjoy small moments, like playing Rummikub or spending time in calm, unhurried environments.

Happy to share a small part of my world with you.
