Micro Services Lead Architect

Responsibilities:

• Participated in a remote, loosely agile work environment with collaboration through Atlassian tools (Confluence, Trello, Bitbucket), Slack, Google Apps (mainly Docs and Hangouts).
• Researched and architect a multi bundled distribution where feature modules could be developed, bundled, and deployed without rebuilding the core application. Core application maintained general architecture, state management, core routing and global services allowing feature bundles to be lazy loaded and conditionally flagged on or off.
• Served as a go-to person for any architectural related needs. Kept weekly session with clients to educate them on enterprise architecture. These sessions made seamless transition of work to clients during roll-offs
• Developed procedures to unify streamline and automate applications development and deployment procedures with Linux container technology using Docker swarm.
• Developed Kube yaml templates to convert docker compose for integrating kubernetes platform
• Configured their Kubernetes cluster and supported it running on the top of the CoreOS
• Used Jenkins and pipelines to drive all microservices builds out to the Docker registry and then deployed to Kubernetes, Created Pods and managed using Kubernetes
• Building/Maintaining Docker container clusters managed by Kubernetes Linux, Bash, GIT, Docker, on GCP. Utilized kubernetes and docker for the runtime environment of the CI/CD system to build, test deploy.
• Test driven development in Spring Boot using Spring4 Runner Integration Test framework.
• Setup and configured build automation and continuous integration with Jenkins running on an EC2 instance.
• Utilized reactive programming with extensive use of observables for local and global state management, mutation observers, routing, etc.
