SmartThings is a market leader in consumer home automation IoT products. I am currently on the Observability team that owns the routing and proxy services for the SmartThings API. We also administer third party tools around logging, tracing and metrics. The SmartThings platform is comprised of a couple hundred microservices deployed in AWS. Technologies in heavy use include Ratpack, Cassandra, Kafka, RabbitMQ, Memcached, Aurora, DynamoDB, Lambda, Kubernetes, SQS/SNS, Memcached, Redis, Terraform and much more.+ Created a new network architecture for the SmartThings platform involving collapsing VPCs, replacing peering connections with transit gateways and adding Route53 resolvers.+ Created and continue to maintain a set of Terraform modules that allow teams to more easily stand up required infrastructure for new services.+ Provisioned Kubernetes clusters in all our environments which includes five AWS regions. These were eventually replaced by EKS clusters operated by a dedicated team, but many of the lessons learned from operating these clusters were rolled into the newer EKS clusters.+ Currently serve on an incident commander on-call rotation for dealing with escalated production incidents.+ Served as the interim director of security for six months. I lead a virtual team that responded to incidents while we actively interviewed and hired a replacement director.+ Served on a cloud architecture board where we redesigned and are currently implementing a new cloud architecture that I originally proposed.+ I helped architect a solution for delivering appliance error codes to property managers when installed in multi-family housing. This allows work orders to be created without the tenants having to raise the issue themselves.+ Assisted support to resolve escalated customer issues.+ I regularly interface with our vendors such as AWS and DataDog, and serve on the Customer Advisory Board for SumoLogic.

Sole architect for a desktop application used for framing and sheathing dormers. The project involved heavy use of Swing, 2D rendering libraries, Guice, TrueLicense, Maven, Mercurial and Git.• Heavy use of trigonometric functions for calculating cuts required for various materials to the nearest sixteenth of an inch.• Calculated center of gravity for irregular shapes to aid in rendering centered labels.• Implemented an algorithm to determine the minimum number of sheets required to sheath an irregular surface.• Complex 2D graphical layouts with components rendered by translating between user and device spaces to ensure everything is visible in the client area and printable for the job site.• Responsibilities included gathering requirements, building a backlog of work, billing client and producing estimates.

Worked on a SaaS solution for IT administrators to manage their virtual infrastructure. This included inventory, patching, virtualization and disaster recovery. Technologies used included C# 5, ASP.NET MVC, HTML, CSS, JavaScript, jQuery, DevExpress, TPL, TPL DataFlow, Quartz, ClickOnce, JSON.NET, TFS, MSBuild, WebDeploy.Activities:• Architected and implemented a highly concurrent and scalable message processing bus using Quartz and TPL DataFlow to process and project event messages coming from a third party.• Placed second out of over 700+ developers that participated in an internal hacking competition modeled after DEFCON and oragnized by the VMware security team. The competition required knowledge of writing shellcode in Assembly, C, Java, SQL injection, XSS, buffer/heap/interger overflows, Metasploit and more.• Created and maintained highly interactive user interfaces with many components and state persisted in session and shared across multiple requests.• Automated deployments to smoke test, QA and production environments using MSBuild and WebDeploy.• Worked collaboratively with a remote team based in Utah.

Developed, supported and evangelized web-based client architecture components consumed by hundreds of developers across the entire Windchill business unit as well as support engineers. Technologies used included Java, JSP, Spring MVC, HTML, CSS, JavaScript, REST, ExtJS, Git, Gerrit, Jenkins and ClearCase.Activities:• Leveraged Scrum, Agile and XP practices to rapidly produce high quality deliverables and ensure dependent teams could build and deliver without impact.• Held weekly office hours to support development teams consuming our components. This generally involved debugging issues and providing design direction.• Participated in conference calls with customers and support engineers to design and debug customer-specific customizations.• Evangelized and piloted a project to convert from ClearCase to Git, which included an automated bridge between the SCMs. Gerrit was also introduced to facilitate code review.• Introduced and eventually replaced the usage of CruiseControl with Hudson/Jenkins within the organization. Held weekly office hours for development teams looking to learn more about Jenkins and why they should make the switch. Also taught more advanced concepts such as creating deployment pipelines and plugin development.• Attended JavaOne and other conferences in order to stay abreast of emerging technologies. Knowledge was then shared with other developers in the form of brown bag presentations and internal newsletters.• Collaborated closely with a remote team in Pune, India.

Worked with clients on a number of web application projects, ranging from supplier management, search and aerospace and defense. Technologies were primarily Java, HTML, CSS, JavaScript, SOAP, XML and heavy regular expression use.Activities:• To increase marketability I accumulated numerous certifications (now expired), including SCP for Java 2, CompTIA Security+, IBM Object Oriented Analysis and Design, IBM Solution Technologist and more.• Rewrote a search engine to tokenize and project search expressions and make full use of the regular expression support added in Java 1.4.• Architected extensible web components for other internal teams to consume and create a next generation web client to replace outdated template-driven user interfaces.• Reverse engineered a customization done by a services team in order to create a fully supported add-on module for aerospace and defense customers.• Championed introduction of continuous integration with CruiseControl, unit testing with JUnit and JSUnit, code coverage with Cobertura and static analysis with PMD/Findbugs.• Collaborated closely with a remote team in Pune, India.
