Data Scientist on the Transactional Pricing Team.

July 2019 - April 2020

Full Stack Developer

C. H. Robinson

Full stack developer for the delivery team for the business data science team at C.H. Robinson. Took data science models and scaled them beyond jupyter notebooks. Scaled applications rapidly during the late-prototyping phase and broke them apart into production microservices. Worked directly with members of the buisiness to deliver rapid positive outcomes through the targed delivery of data-science tools.

April 2017 - July 2019

Python Developer / Bioinformatics Scientist

Omaha's Henry Doorly Zoo

Worked with researchers in the Conservation Genetics Lab to make their experiments feasible and contributes to scientific publications. Created and modified highly parallel Python3.5 scripts to manage bioinformatics applications running in primarily Debian environments. Wrote scalable Python3.5 applications to process, analyze, and visualize next generation sequencing data. Built the lab’s on-site super-computers and handled the set-up of a Beowulf cluster computer. Handled environment setup, compilation of software, and job submission to the super-computers at the Holland Computing Center at University of Nebraska through SLURM and OpenStack. Developed and maintained web applications to connect researchers with complex scientific datasets in Python2.7’s Flask on the Google App Engine and PHP5’s Laravel on Heroku. Analyzed large multi-year radio-collar geographic datasets in Python, ArcGIS, and R. Packages Docker images to run and distribute software to use on lab and field computers. Ran analysis for gene annotation (Maker, Augustus), eukaryotic genome assembly (Supernova, Abyss, Trinity, AllPaths-LG, MaSuRCA, SOAP, Platanus), and species phylogenies (BEAST, RAxML, MrBayes, PhyMl, PAML).
