Responsible for the development and integration of the new network management system to support our in-house datapath for Intuition.Collaborated with System Architects, PLM, and Management to drive the Intuition NMS to a working system. Taught co-workers required skills in architecture, code layout, and fostered a collaborative work environment.Introduced TDD, and developed a JIT TDD work environment which helped increase the number of unit tests for the implementation of the most important parts of the system.Worked on architecture, and prototyping all required microservices required to build out the existing framework to fully support the Intuition datapath. This included re-writing existing microservices, creating, and helping to productize new microservices in Python, NodeJS, and Golang.Utilized technologies: Python, NodeJS, Scala, C++, GoLang, helm, kubernetes, kafka, MirrorMaker2, Strimzi, etcd3, MinIO, AWS, EC2, EKS, ECR, S3, Lambda, and related servicesFrameworks: AngularJS, PostgreSQL, Timescale, kafka, Prisma 5.x, Apollo, GraphQL, Mustache, Worker ( NodeJS )

Worked on building out a scalable, cloud based network management system. Introduced architecture and microservices to meet the requirements and adopt the new system to our in-house datapath backends, Dialog, Evolution, and Velocity.Utilized technologies: Python, NodeJS, Scala, C++, Golang, bash, helm, kubernetes, AWS, EC2, EKS, ECR, Lambda, and related services.Frameworks: AngularJS, PostgreSQL, Timescale, kafka, Prisma 1.x, Apollo, GraphQL, Worker ( NodeJS )

Manage small team of globally distributed developers and testers to drive the scalability enhancements of our iVantage NMS system, using agile development.Achieved ten fold scale improvements through progressive code changes on the server and client side. Oversaw porting of our NMS services to 64bit. Architected and helped implement a framework to distribute compute intensive tasks over multiple NMS nodes to further improve scale.Architected and helped implement a scripting interface to the legacy system which is used as the basis for our customer facing RESTFul API. This interface can be used to completely replace the gui interface with a M2M interface. I believe in taking responsibility of the success and failures of your team and push hard to improve predictability, reliability, and the quality of the deliverables.

Manage and lead a globally distributed team of six full­-time senior software engineers to deliver high quality products to our existing customer base.Following the scrum development methodology we were able to deliver one major release within a short period.Organized weekly learning sessions with the team and created a vision statement for the Product Solutions Team. Setup weekly one on one sessions and created a development plan for my direct reports.Drive outstanding issues to conclusion and take responsibility for the successful delivery of the sprint goals for my team.Work in close cooperation with engineering and PLM to address quality, and scalability concerns in order to deliver world-class new products to end customers as part of the expanding software portfolio.

Manage and lead a team of eleven full-time software engineers to build the next generation, highly scalable, web based, network management system.Worked in close cooperation with our development team in Cranfield, UK and ensure that design and implementation of the NMS meets all system requirements. Improve communications flow and interactions across departments.Having established a semi-agile development environment our team was able to achieve the set goals on time and to lower the overall project risk by identifying issues early on in the development cycle.Manage the hardware and software requirements for our teams infrastructure needs. Engaged all involved parties across departments and on all levels, to successfully lead the integration effort of the overall inter-component integration to successfully deliver the new products to the systems test team.Built the strongest team in our department through one on one sessions, learning sessions, and in-depth technical discussions. Actively engaged the engineers during the decision phase for new features and involved PLM and the UX teams in the process.
