• Create documentation for processes, guides, design and support materials.

PROJECTS AND ACHIEVEMENTS

• Green Brain weather and soil-moisture monitoring application
  I support an up-to-the-minute weather and soil moisture monitoring application for wine growers. The application covers 1000's of regional weather stations in key areas such as Adelaide Riverland, Barossa Valley, McLaren Vale, among others.
  
  I recently completed a project where I moved over 5 billion sensor readings to a time-series database, reducing the historical data by 98%. Combined with SQL query optimization and code refactoring, this led to a 50% reduction in database storage, faster processing, and improved web performance.
  
  
• Green Brain - Next, CI/CD and IaC
  I led the design and implementation of Green Brain's next-generation product suite, focusing on enhancing security, performance, and billing capabilities.
  I also established branching strategies, continuous testing, build and deployment processes using GitLab CI. Furthermore, I utilized Terraform as an Infrastructure as Code (IaC) solution to manage and deploy to AWS.
  
  
• Streamlined data ingestion
  By standardizing the data format, I streamlined the integration of all data and the IoT ingestion pipeline. This migration resulted in enhanced efficiency and better maintainability of the system.

PROJECTS AND ACHIEVEMENTS

• GAIA's NDVI web application
  I maintain GAIA's (now part of Green Brain) web application.  This application provides up-to-date satellite imagery and NDVI (Normalized difference vegetation index) calculations for the entire vineyard. Serves as a valuable tool for wine growers, enabling them to monitor the health of their crops effectively.
  
  

• Rebuilt satellite imagery pipeline using Maxar ARD
  I quickly familiarized myself with Python and rebuilt the satellite imagery procurement and processing pipeline using Maxar's new ARD (Analytic Ready Data) service.
  
  

• Wine Australia National Scan 2020
  We delivered a report to Wine Australia that analyzed wine regions around the country. The analysis was conducted using satellite imagery and AI techniques. The report provided valuable data that Wine Australia can utilize to produce informative infographics and gain a better understanding of the industry's size.
