DevOps Engineer and Developer in Woodbridge, VA, United States

A transportation POC demonstrating a connected fleet, which provided a single map view of real-time vehicle location and metrics using multiple telemetry data providers with vehicle detail drill-down and real-time engine fault alert, analysis, and service center remediation.

The POC's microservice architecture included the dashboard UI, fleet query for real-time fleet coordinates, truck details to drill down on vehicle make or model, odometer service to drill down on engine metrics, service center for locating remediation services, and data export for exporting to CSV.

I used Spring Cloud Data Flow for telemetry ingest and GemFire for real-time map display. I also used Greenplum for engine failure predictive analytics, Jenkins for CI/CD, and Cloud Foundry for deployment automation.

A content and collaboration SaaS platform built for CPAs and their clients. The platform provides client or project workspaces with built-in contacts, messaging, document management, databases, and analytics. Additional integration modules provide tax-specific features like engagement letter signature tracking, tax organizer, tax return work papers and tracking, 8879 eSignature tracking, and client data master sync.

The platform is hosted on AWS using microservices and serverless paradigms written in Node.js, TypeScript, React, and Redux. AWS EC2 instances and ECS Fargate are used for container deployments along with Lambda for serverless events modules. Aurora, RDS, DocumentDB with MongoDB, and DynamoDB are used for various back-end system storage, and S3 is used for document management. Finally, Cognito is used for authentication management and X-Ray for enhanced monitoring and diagnostics.

A paper-to-digital transformation project aimed to migrate the paper-based workflow for professional athlete drug testing to a fully online mobile application with supporting back-end cloud services. The mobile application replaced the paper forms completed by the drug screeners during live events and allowed athletes to update their testing and location statuses.

The mobile application supports both iOS and Android using React Native, supporting both tablets for screeners and phones for athlete users. The back end is hosted on AWS using AWS Amplify AppSync and DataStore for mobile data synchronization, Node.js Lambda services for handling database events and locking, and AWS RDS for SQL Server with integration between Microsoft DevOps, TeamCity, and AWS CodeBuild, CodeDeploy, and CodePipeline for CI/CD.

Banking Industry Architecture Network (BIAN) is a membership group committed to developing open standards around banking and financial services. A key deliverable of this group is the BIAN Service Landscape model, which defines a comprehensive services architecture for financial transactions and facilities.

I developed an implementation of this standard for the Java Spring framework to accelerate adoption and implementation by the online banking industry. This library is an implementation of the BIAN model leveraging the Spring framework, and it allows a developer to rapidly create BIAN-compliant services while hiding much of the underlying BIAN model details. See www.bian.org for more information on BIAN.

This library leverages not only the Spring framework but a number of the Spring Cloud services components and facilitates building robust and resilient cloud-native BIAN microservices. It is aligned with the Wave 3 approach of the BIAN implementation model. The used Spring components are Spring Boot, Spring Cloud Netflix, and Spring Cloud Stream.
