BMW: Apps and Services

I was a senior member of the team building systems to provide electric car drivers with an optimized way to charge their vehicles called bmwchargeforward.com. This app connected many internal BMW systems but interfaced with Power companies for up-to-date energy data. In addition, I coordinated with top vehicle manufacturers and utility companies to build a system to securely send electrical grid data from the utility companies to each electric car manufacturer.

Sr. Enterprise Application Engineer

2018 - Feb 2020

AFS Logistics

I worked as a lead engineer on a team building a new Transportation Management System from the ground up using a microservice architecture. Spring Boot, gRPC, Protobuf, Kafka, Elastic Search, Vue.js, PostgreSQL, Docker, Kubernetes, Helm.

I maintained legacy applications, worked on improvements and new features of existing products, and architected new applications.

Projects

• BMW Charge Forward - This project includes a collection of BMW internal services providing vehicle data sources. They are used to optimize electric vehicles charging times. To manage the streams of vehicle event data, AWS Lambda, SQS, and Kinesis were built together in a Typescript mono repo. The backend was built with node Nest.js framework and PostgreSQL.

• Transportation Management System - This project includes a collection of applications and microservices deployed with Docker, Kubernetes, and Helm. Projects I participated in: A CRUD application is the main entry point into the system. It uses Spring Boot, MS SQL Server, and Vue. A Rating System designed for high throughput and consists of multiple microservices using Spring Boot, Golang, Protobuf, gRPC, Redis, PostgreSQL, Vue. A Document Manager built to control the ingestion of physical documents using Spring Boot, Protobuf, gRPC, Websockets, RabbitMQ, PostgreSQL, Google Cloud API, and Vue. A Delayed Messaged Delivery service that can scale for high volume built with Kafka, Redis, and Spring Boot.

• Gohlay - I am writing an open-source tool to reproduce the Kafka delayed/scheduled message system using Golang Gohlay WIP. It has a much smaller footprint and can scale more efficiently without the dependency on Redis.

• Dynamic EDI parser - This reliable EDI parser is able to convert any EDI file into an object format of choice (XML, JSON, etc.). I developed the algorithm that utilized specific Java class definitions to know how to parse any type of EDI file. This gave us the power to define broad or specific rules in each Java class file that would teach the algorithm how to read any EDI file. The classes could then be extended to build custom file parsers.
