What I'm looking for

I'm seeking a collaborative role building scalable data systems or full-stack solutions where I can reduce errors, deliver measurable business impact, and grow technically.

I am a data-focused software engineer and analyst with over two years of experience building and maintaining data pipelines, debugging production systems, and delivering end-to-end solutions that support commercial decision-making.

I have applied Python, PySpark, SQL (Snowflake/BigQuery), and cloud tools to identify anomalies, reduce error rates, and improve reporting accuracy for retail clients such as Woolworths NZ and Countdown.

My work reduced dataset error rates from 20% to under 0.01%, resolved discrepancies exceeding $20 million, and introduced feature and workflow enhancements that improved user trust and operational efficiency.

I collaborate closely with stakeholders, manage expectations, validate dashboards, and iterate on product feedback; I seek roles where I can scale data systems, influence product outcomes, and continue growing across full-stack and data engineering domains.
