PROFESSIONAL EXPERIENCE:

Confidential, Gaithersburg, MD

Software Architect / Development Lead

Responsibilities:

• Serve as Technical Lead for the development and architecture around automation, integration, and workflow management (orchestration) solutions for the Application Delivery Team. Lead Sr. Engineers to assist in development and implementation of both front and back-end services of my initial design. These initiatives effectively reduced cost, time-to-execute, and overall technical debt.
• Developed a portable service in Python that converts any local file, directory, shell command, or script, into secure and interactive REST API with no development (single CLI command) . This gave the ability to reuse hundreds of scripts, instant automation and web service mockup, and provide engineers who cannot/do not want to program REST APIs.
• Created a web UI dashboard that dynamic displays all REST API resources of a given location, all metadata on the given resource, and real-time monitoring on current health status without having to setup resource configuration or payload testing (a la postman, etc).
• Architected a “no-flat-file” approach to deployment workflows around the build and provisioning of Docker images and container namespaces.
• Created abstraction-layer for Docker inventory management and remote execution automation; providing the ability to interact directly with running container applications regardless of native or Kube/OSE platform management.
• Created portable ChatOps XMPP/Jabber bot and CLI with easy-to-use AI framework for the execution of workflow patterns called within OO style methods. Execution actions are recorded, patterns are “learned”, and guidance/training can also be applied through scripting.

Sr. Systems Engineer

Responsibilities:

• Design and support high-speed bulk data import/export and archiving solutions for distributed cache technologies used by customer-facing company products. Such technologies include ElasticSearch and Hazelcast.
• Create orchestration workflows for AWS services and open source batch processing technologies such as Storm, Kafka, and Zookeeper.
• Build query REST APIs for multiple ACID database services (AWS RDS), message queues, and system logs.
• Architect high-availability design for cloud-enabled microservices within the AWS infrastructure.
• Implement CMDB with distributed cache whereby scripts and product AIPs can also be stored within the database for self-service functionality such as application deployment and instance provisioning. Added extensions for data backend support for bootstrapping applications such as Puppet.
• Develop SSL crypto management and notification system for company products; such features include certificate auto creation/signing, deployment, and expiration notifications.

Engineer IV - Software Development

Responsibilities:

• Serve as Technical Lead for the development and administration of automation solutions for server virtualization environments. The scope of automation includes provisioning, application deployment, guest OS monitoring, hypervisor reporting, and cloud-based resource control. Supported virtualization technologies include VMWare and KVM.
• Design an in-memory datagrid (distributed cache system) that hosts the read-only data from Confidential Datawarehouse Hadoop batch jobs, in efforts to reduces query load on back end and provide real-time response and replication. Using “data as a programming language” concepts, the system supports Clojure to create a “nebulous programming platform”, eliminating technical debt concerns regarding management of script code, output, and params.
• Created orchestration for server environment provisioning using cloud services such as AWS and OpenStack. Specifically used OpenStack internally at Confidential to provide applications as a service. Was on the governance board and automation/orchestration around implementing OpenStack. For the orchestration development, primarily worked with the Nova, Swift, Cinder, and Quantum APIs to establish provisioning workflows.
• Develop a modular, extensible, workflow-driven orchestration system with a dedicated API as well as a web and terminal interface. This system contains numerous adapters for interoperability of various enterprise applications, automation services, and frameworks, enabling the user to build their own custom process-driven solution.
• Develop a unique, portable “cloud-based infrastructure services” application suite, whereby network services such as DNS, DHCP, Web, FTP, SMTP, among others are connected to its distributed in-memory database. The system contains a comprehensive REST API, PKI-based authentication, and role-based access. It has a simplified, self-executing, single application directory deployment design that requires no dependencies or complex configurations.
• Create Fabric (Python API for remote execution and configuration management) fork that includes password encryption, improved logging, system commands library for a myriad of Unix operating systems, integration with version control systems, XML and JSON parsing, and persistent monitors for action-based triggering.
