I help evolve and maintain Kubernetes infrastructure across cloud and onprem environments that run multitenant applications.Stood up Terraform Enterprise infrastructure that saw a high adoption rate.Written golang application to support workloads in our clusters.Written Ruby integrations with azure.Debugged OS/Kernel level bugs.Implemented Kustomize scripts to help drive how we deploy our core stack to our clusters.Updated a fleet of clusters that combined support core workloads across 3000+ nodes with no downtime.

Led the effort to migrate a monolithic application to a microservices architecture leveraging cutting edge technologies such as Kubernetes and Docker.Deployed and managed various Kubernetes clusters using KOPS that served as our QA, Production and Dev environments.Used KOPS’ cluster file definition to create a CI/CD pipeline that served as our “infrastructure as code” deployment process.Wrote a set of Golang microservices that handled TCP connections from our IOT fleet and published them to a Kafka topic. This included a gRPC echo service to duplicate the messages to other environments such as QA and Production.Wrote a Kafka Stream application that used the Streams API stateful features to aggregate sensor readings which resulted in total counts.Wrote a set of Node.js microservices that served as the processing engine for IOT messages which accumulated “complete” messages and distributed them to their uniquely keyed topic.Wrote a proxy service that runs as a side-car with the Swift processor. It proxies Kafka messages as a gRPC stream.Containerized a Swift server application and deployed it as part of our microservices.Planned and built a data stream infrastructure to meet our short-team goal of migrating to microservices with the long-term goal of it becoming the foundation of a platform that will help accomplish the company's vision of becoming the data broker of parking.Deployed and maintain Kafka and Zookeeper clusters on Kubernetes as Stateful Sets that serve as the backbone of our new platform.Deployed the Confluent Schema Registry and documented best practices and guidelines for data modeling using Avro and the concepts of schema compatibility and evolution.Deployed and seeded various Cassandra db Stateful Sets to model and store IOT data.Deployed Prometheus and Grafana to work in unison with Istio to provide quick insights to metrics from microservices deployed to our cluster.

Designed and developed core application to transform data via JSON configurations, reducing development time and redundant code and modules. Led team in prescribing to TDD to build sustainable and testable code; enhancing development phase. Restructured tooling used to transpile, maintain, and lint code; reducing development time, and enhancing user experience, a process adopted by our team.Developed efficient data transforms leveraging profiling and optimizations, and provided training to team as needed.Introduced improved Javascript standards and applications to replace Java; enhancements included JS concepts of inheritance, composition and OO. Refactored dated JS code to better utilize design patterns, eliminating the need to touch multiple files and codes.Promoted use of ECMA2015 to better utilize all accompanying new features. Developed nodejs modules for Point-of-Sales systems that gathered data continuously and transformed it to JSON format to save on Mongo, subsequently fueling client-facing data analytics and information tools that provided restaurants with current data analysis and insight.

Engineered multiple full-stack applications with NodeJS, Knockout, Foundation, and various other libraries.Designed and planned customized experiences for each client utilizing various types of services in addition to normal features offered; including integration with SOAP service, CORS and integration with AWS services. Developed custom services in Python for clients outside the main platform; including cron services to synchronize databases, CSV files importing from S3 bucket, file uploading/downloading through AWS S3 and custom reporting. Innovated new software to ensure easier web applications development; widgets maintained standard from application to application.Partnered with Account Managers and clients to streamline development process from requirement gathering to release and debugging.Handled multiple bug report tickets from other applications, meeting all deadlines.Leveraged HTML, CSS, SASS and other front-end technologies in executing all duties. Maintained and enhanced internal Oracle data-pump application written in Ruby, development Virtual Machines using Chef and Vagrant running on VirtualBox/VMWare.

Developed, maintained, and improved internal trouble ticketing application developed with Java EE 5 and Spring Framework in a 24/7 geographically diverse data-center.Tested, tracked and debugged application defects. Utilized SCRUM and Agile development methodologies to complete projects within deadlines.Designed and developed JUNIT tests to optimize daily application testing, and to improve reliability of internal trouble ticketing system. Designed and developed new and exciting web application in MVC architecture using EXTJS 4 as UI, replacing existing Java Swing UI.Adapted and created new JavaScript and JSON files to configure web app with old application.Exposed and migrated system’s EJB server-side interface to REST interface (via Jersey), modifying existing classes, and creating new classes to sustain the migration. Created and presented various presentations to the team on developing RESTful server-side interfaces.Produced various reports analyzing trouble ticket volumes to track improvement on automation processes being developed to improve system performance.

Developed multiple Visual Basic applications that executed simulations of solar position scenarios in relation to a solar cell’s position on the ground based on the parameters given by the researchers using it. Designed the industrial process of the company’s new product before actual prototype development.Worked extensively with MS Excel, Access and Project to develop project time-lines, databases of simulation data and market-research matrices for the company.
