About Me
I'm a Master of Computer Science (Data Science and AI) candidate at the University of Sydney, completing coursework in November 2026. I have commercial experience building Python- and SQL-based ETL workflows, automating data processing and reporting, and validating data across PostgreSQL and MySQL databases. My university projects include a PostgreSQL database with trigger-based business logic and machine learning classification models. I'm seeking graduate and junior roles in data engineering and data analytics across Australia.
Data Engineering
Building Python ETL pipelines that load CSV, Excel and JSON data into relational databases, with data quality checks and reconciliation
Databases & Modelling
Designing relational schemas from ER models and automating business rules with PL/pgSQL functions and triggers
Data Analysis & ML
Cleaning and exploring datasets, engineering features and comparing classification models
Experience
Software Engineer (Part-time)
- Developed and maintained Python ETL pipelines to extract, transform and load CSV, Excel and JSON data into PostgreSQL and MySQL databases for business reporting.
- Wrote SQL queries to validate data loads, reconcile record counts and generate business reports.
- Automated recurring data processing and reporting workflows with Python (Pandas), reducing manual spreadsheet preparation.
- Built data quality checks (duplicates, nulls, consistency, reconciliation) and resolved failed loads by tracing root causes through execution logs.
- Worked in Agile sprints with code reviews and Git/GitHub pull requests, and documented ETL workflows and database changes.
Key Project: RideThe15 - Rideshare & Carpooling Platform: built data-processing workflows and operational dashboards and scorecards with daily, weekly and monthly trend analysis.
Business Analyst Intern
- Gathered, analysed and documented business requirements, translating operational processes into structured functional requirements.
- Developed Python automation scripts to process inventory, sales and customer data from Excel, CSV and other structured sources.
- Created reusable validation scripts (Pandas, NumPy) to detect missing values, duplicates and formatting issues, and validated imported records in SQLite and PostgreSQL databases.
- Prepared functional and UAT test scenarios, performed API testing with Postman, and documented workflows and user guides.
Key Project: Wood Management System - Timber Depot Operations & Billing: supported purchase, sales, stock and pricing requirements for a multi-depot billing system, validating master data and transaction reports.
