Technical Lead for the Data Engineering team responsible for maintaining the petabyte-scale Braintree data lake pipeline and related infrastructure that powers reporting, business intelligence, and analytics for Braintree. The stack is built on Kafka, Spark, Airflow, and Iceberg on Amazon EMR, with some supporting applications running in Kubernetes. Built out the CI/CD process for the various applications that make up our stack. Solved many tricky data quality issues that have arisen. Provide mentoring to other developers on the team.

Added an event message bus to core systems to enable gradual transition to a microservices architecture. Stabilized the Managed WordPress Product. Architected and led development of the Managed WooCommerce product on a Kubernetes platform. Re-architected those products from a single-tenant to a multi-tenant architecture to enable better performance and scaling of the product as it grows. Provide technical leadership to other team members and help shape technical direction with management.

Moonlighted with ZipZap to help convert their webapp and mobile apps from 3 separate codebases into a single codebase built as a SPA with React, and then converted to mobile apps using Phonegap. This also involved adding features and fixing bugs in the Flask-based Python API that powered the backend.

I worked on the Cloud Big Data product that makes deploying big data clusters (Hadoop, Spark, Kafka, etc) on the cloud easy. I rewrote our provisioning engine to utilize Taskflow, Libcloud, and Ambari so we can add new features at a more rapid pace and give the customer more flexibility in the topology of their clusters. I added Spark and OnMetal support to the product, which made us first to market for both of those features. I led the development of a Sentiment Analysis sample application using Spark, Kafka, and node.js to showcase the platform and give customers an idea of what's possible with the technologies. I provided leadership on the team by mentoring new developers, giving presentations inside and outside the team on the technologies we utilize, and working with the Open Source communities for the projects we rely upon. As part of those duties, I was invited to be a core reviewer on Openstack Taskflow. Other notables include: 1st place entry for Ambari Hackfest, co-organizer Datastores Technical Book Club, team representative to ObjectRocket Jedi Council (architecture review committee), and part of the Emerging Technical Leaders Training Program for Rackspace.

As a Team Lead, I provided direction and mentoring for other developers on the team, reviewed code, determined priorities, and took lead on projects with which I was directly involved. As part of my responsibilities included recruiting and interviewing potential developers and engineers for the team out here in Scottsdale, I helped the team grow significantly, and provided the mentoring and leadership necessary to make the remote team a more productive asset to the company. We followed a Kanban process, and I was frequently involved in iterating and streamlining our development processes, including further automating our testing and release processes and improving the infrastructure and tools related to those processes. When I wasn't providing leadership or working on process, I was a primary contributor to the codebase I helped build as a Senior Software Engineer, and was one of the primary go to guys for complex urgent issues that required my expertise and work ethic to resolve quickly.

During my time as a Senior Software Engineer, my primary accomplishment was to build the REST API and customer-facing management portal for LiquidWeb's cloud platform StormOnDemand. Due to my work on automating testing of our cloud platform and API, we were able to build and launch a competitor to Amazon's EC2 with a small team of developers and engineers in thirteen months. The work I did on the frontend to share resources between Storm's and LiquidWeb's management portals saved many hours of work and allowed us to easily do simultaneous feature launches on both sites. Since the launch, I was the primary contributor to a number of other features, such as Load Balancers, but I spent the majority of my time improving internal systems. As such, I contributed to a rewrite of our billing system that has reduced errors and sped up our billing process for both our customers and our employees. As part of that project, I was a primary contributor to a new code framework that has greatly sped up development of new features by providing common idioms and patterns in a reusable, intuitive manner. Additionally, I built an auth and access control system that's used by many internal systems and our REST API, which gives us fine-grained permissions control with minimal overhead, built out and automated deployment of development and staging environments, wrote the tools used to manage servers and release code, and significantly enhanced our automated unit test suite.

At the MySite portion of United Online, I was a major contributor to a REST based API for handling large volumes of file uploads. I added a declarative schema that was used to generate the WSDL for the SOAP interface as well as generate the routes for the JSON-based version of the API. This made it simple to add new methods to the API without having to add a lot of boilerplate for the different serialization formats. We used this to back a photo album addition to our dynamic website builder. When the parent company decided to shut down our office, I was one of the few personnel kept on board to help with the transition.

Worked on online tools for Noni distributors to manage their downlines and generate leads. Also worked on the e-commerce store for selling their products online.

Park City, Ut, Us

Built a sales acceleration report to allow marketing to either promote or discount products based on their sales trends.

Minneapolis, Mn, Us

Worked on a rewrite of their online flight-booking software.

Led development of an online site builder application for MLM reps to manage their online presence and downlines. This was used by various MLMs such as Tupperware and Amway.
