Software engineering, building software for retail products.• Contributed to software, that uses data science to estimate similar or same cars, that increased sales by many millions in a year timeframe• Working on customer prioritization of sales leads by phone, web leads, and subsequent follow-ups; poised to add multi-millions in overall revenue• Creating a near real time eventing feed of new features, to a feature store to increase the 0-24 hour profile of viable customers by as much as 30%• Updating the signature of a MLOps pipeline from a stale process, to a near daily, retrained model• Actively merging the best skills of a software engineer and a machine learning engineer into one super user• Creating an interaction model between data science, machine learning, and served models. This pattern grossly outways most "in-play" or open source ML Ops pipelines in existence.

Software engineering to build a robust, resilient, durable solutions that leverage enterprise standard CICD pipelines, to automate building, restoration, backups, and multi-site availability• Built a completely self-service onboarding system, to one of the largest credit card companies, to one of our largest Elastic Stacks. The stack reduces hardware needs, moves inbound log processing from a server-side pull, to completely client side push, making it completely self-service.• Publishing learnings of Java virtual machine theory, effective heap vs stack memory utilization and control, and minimizing hardware while maximizing effective usage of exceptionally large clusters.• Building cross-site replication, using Kafka, to offer replication across numerous physical regions, to ensure as close to 100% uptime as possible.• Integrating numerous tools into one visual, that captures the best of numerous monitoring solutions, to offer a collection of the best available options into one tool. The vision is to go from a global view, to drill down to the class and kernel level, to then find issues across a stack of machines.• Other value adds include integrating micro-services from third party vendors, to add business facing data where applicable, and adding machine learning to drop incident response time to less than 5 minutes.
