Jan 2021 - Mar 2022

Staff Software Engineer

Kansas City, Missouri, United States

The COVID-19 pandemic was an abrupt change for everyone, but also led to a career accomplishment.The pandemic halted almost all in-person research at Stowers for several weeks. But Stowers scientists designed a surveillance study to test for SARS-CoV-2 in its staff population, providing reasonable certainty for returning to in-person work.Stowers scientists repurposed on-premises equipment normally used for scientific research to test for SARS-CoV-2 virus in saliva instead of nasal swabs.I and two other Engineers were tasked with building custom software to conduct this study. All on-site staff would have saliva and blood tested several times per week. Our software was to facilitate specimen intake, compliance monitoring, analysis, and reporting. And a deadline of a few weeks.We worked quickly and tirelessly to build COVIDTrack: a web-based software for conducting the COVID-19 surveillance protocol designed by Stowers scientists. I demoed our kiosk intake and backend software to C-suite and study investigators.The source code was made open-source for others to adopt the protocol and facilitate their own return-to-work plan: https://github.com/stowersinstitute/COVIDTrack/graphs/contributorsSoftware features:• Support specimen anonymization at all steps for triple-blind adherence• Generate unique test tube barcodes on sticker sheets• A kiosk software for returning saliva and blood specimen by scanning test tube barcodes and answering a few questions• Intake and viability verification of returned specimens• Storage management to track where each specimen is stored• Ingesting a CSV file of qPCR and RT-PCR results from well plates and mapping results for each specimen• Highly confidential access to test results, limited to 2 individuals

Apr 2020 - Dec 2020

Staff Software Engineer

Kansas City, Missouri, United States

After previously gaining the team's trust as a Tech Lead Consultant, my role shifted to leading small Product-focused teams building their business-critical software called LIMS (Laboratory Information Management System).LIMS is an end-to-end platform for investigative biomedical research from conception to publication. It allowed investigative scientists to organize and collaborate on their research, and request scientific services from world-class SMEs in the Institute's core services departments.I would regularly collaborate with world-class SME's to understand their scientific function and allow lab members to request service and receive results through LIMS.My work straddled between building reusable LIMS framework features with another Tech Lead, and leading small Product-focused development teams building Product-focused work. • Advance role-based access control (RBAC) using a mix of LDAP and local role management• Sample Management: sample tracking from origination to consumption, annotating Ontology metadata from Open Biological and Biomedical Ontology Foundry, aliquot and mother/daughter lineage, faceted search• Storage management, tracking Sample locations across specific freezers, racks, boxes, and well plates• Annotating and publishing raw scientific data (up to 1TB large) to a public Open Data Repository (ODR)• Proteomics analysis requests and analysis results• Microscopy asset management and time reservation with scheduling and calendaring• Inter-organization publication requests and journal publication tracking

Jan 2015 - Apr 2020

Technical Lead

Kansas City, Mo

Stowers sought my help to improve their 5-person Engineering team's productivity and modernize their 1 million-line legacy codebase (no framework PHP and JavaScript). The "team" could only assign 1 Engineer per project, released only once per month, was inundated with bugs due to manual testing and limited version control use.After 2 years of hard work and coaching, the team was releasing daily, writing automated testing to guard against regressions, using pre-merge Pull Requests to share knowledge, and championing a culture of high quality, knowledge sharing, and mentorship. My work eventually allowed the team to scale from 5 Engineers to 10 Engineers.• Establish a new development platform alongside their legacy system. REST API backend (PHP, Symfony 2) and JavaScript frontend (ExtJS).• Ongoing rolling replacement of old functionality with new functionality.• Migrate from SVN to git and train Engineers• Introduce and mentor Engineers in testing mindset, unit testing, functional testing, API testing using PHPUnit• Introduce pre-merge code reviews and establish a positive PR culture• Automate deployment instead of manually building releases• Automate dev environment provisioning on local machines• Automate provisioning environments for each git branch and PR (way before GitHub "Codespaces" was a thing)• Profiling PHP codebase for bottlenecks using Blackfire.io, Xdebug, XHProf• Add performance tracking and exception monitoring
