• Provided DevOps expertise to build, migrate, secure, and maintain multiple production systems on AWS and Kubernetes platforms.• Wrote Infrastructure-As-Code (IaC) to deploy a hardened, Air Force accredited DevSecOps Pipeline (DSOP) on top of Cloud One, which made use of Packer to build a DISA STIG-hardened AMI, and Terraform to deploy cloud infrastructure, all powered by Jenkins. Additionally, created GitOps deployment pipelines with ArgoCD and Gitlab to automatically deploy dozens of secure services to the DevSecOps pipelines, including customized Platform One Big Bang Helm charts and Iron Bank containers. This DSOP was deployed and certified in IL2 through IL6 environments.• Developed custom CI/CD pipelines with Jenkins pipeline jobs and Ansible playbooks to constantly test, validate and deploy systems to AWS as part of multiple on-prem to cloud migrations.

• Designed and implemented a cloud-native, petabyte-scale geospatial data pipeline and web mapping service, which reduced the time from satellite image acquisition to usage by the customer from a month to an hour.• Created and deployed a RESTful machine-learning web service using Tensorflow, which was capable of categorizing input images into over 1,000 categories. This web service ran a model retraining and fine-tuning process nightly, then served the updated model the next day.• Utilized 2.8 billion open-source sentence-pairs for training a Neural Machine Translation (NMT) framework, which supported ten language pairs, and was built on top of PyTorch using a transformer architecture. The NMT web service was deployed to air-gapped environments, providing cutting-edge translation quality and saving countless manual translation man-hours.

• Lead engineer and contributor for the Processing, Exploitation and Dissemination (PED), Mission Command (MC) and C4ISR capabilities.• Responsible for all technology decisions affecting the software development lifecycle and the SOF domain, including SIGINT, GEOINT, COP, TECHEX, Mobile Applications and Web Services.• Created a common platform and software architecture which allows systems to be rapidly integrated and greatly increases team effectiveness and cohesion.• Lead multiple agile software teams with a track record of rapidly delivering capabilities to the warfighter.• Responsible for the processing pipeline and infrastructure for petabytes of structured and unstructured data on multiple projects. My experience covers the full data lifecycle, starting at ingestion, through extract-transform-load (ETL), on to the analysis and exploitation side using bespoke algorithms on top of map-reduce technologies (Hadoop/Pig/Hive). Once the data was fully processed, it was loaded into PostgreSQL or ElasticSearch and served to the end-user via a RESTful web service using Python or NodeJS, with a ReactJS front-end.

• Responsible for the logistics and training requirements for 285 Army Soldiers.• Planned and coordinated signal assets for both Company and Battalion exercises.• Conducted Basic Training as the Company Executive Officer at Sand Hill, Ft. Benning, GA

Orlando, Florida, Us

• Lead software engineer for a Java-based simulation and C4I messaging translation system.• Created a Java-based automated test harness for multiple live, virtual and constructive simulations which provided for automated component, system and system-of-systems tests.• Developed high-performance simulation network translation protocol software which enabled the inter-operation of Live, Virtual and Constructive simulations in real time.• Researched and developed a goal-based planner for both DARPA's Real-World 3D game engine as well as the DoD's OneSAF simulation system.
