  • Managed junior software engineers, mentored their technical development with pair programming and code reviews while helping to balance their personal career objectives with company goals.
  • Led development of internal web applications. Creating the data model, API, and frontend layer.
  • Developed ETL and ELT pipelines for integrating Marketing, Manufacturing, and R&D data from SaaS applications and internal databases into a Snowflake data warehouse using Luigi, Prefect, and DBT.

Bioinformatics Cloud Engineer

Second Genome 2018 — 2019

  • Converted bioinformatics pipelines for processing genomic and metagenomic data into serverless, containerized applications using Docker, AWS Batch, AWS Lambda, AWS SQS.
  • Spearheaded python code consolidation within the company into a single unified library, enforcing test-driven development and software development lifecycle practices.
  • Developed ETL pipelines to automatically scrape NCBI and IMG databases and integrate them with private datasets into data warehouses

Postdoctoral Research Fellow

Caltech 2014―2018

My role was the head bioinformatician for a diverse group of microbiologists, chemists and data scientists at the California Institute of Technology (Caltech). My day to day tasks included the processing of genomic and proteomic data, and generating analysis summaries and plots using statistical software and programing tools such as R and python. As part of this role I was responsible for the production of automated pipelines for data analysis and have developed numerous tools and scripts for processing genomic data. I implemented SQL databases to store the extensive genomic and proteomic data that were generated and developed simple interfaces such that other members of the group could access this information without in-depth knowledge of SQL.

Graduate Student

University of Quensland 2010―2014

My PhD research focused on metagenomic analysis of microbial and viral communities from engineered ecosystems found in wastewater treatment plants. Throughout my PhD I was at the interface of microbial ecology, chemical engineering, and computational biology and have gained many skills ranging from microscopy, reactor operation and computer programming. I developed a number of bioinformatic pipelines and substantial computer software in perl, python and C++. My background in molecular biology allowed me to place the inferences of metagenomic data into a broader biological framework and work with other members of the lab that did not have computer skills.
