Senior Full-Stack Software Engineer

About me:

Self taught full stack software engineer with 6+ years of professional experience.


2017 - Present

(Lead) Developer - ViriCiti (now part of ChargePoint)

Together with an amazing team I'm building, maintaining and owning multiple legacy & modern services/architectures in our domain driven microservices framework. With these people, a "you build it you own it" mentality and a passion for new technologies, it is an extremely motivating and satisfying place to work. One day you're digging in the bits and bytes of a CAN-frame, the next you're spinning up 12 replicas of a service you built.

  • Massively refactored and improved legacy event streaming service
  • Built efficient Kafka to AWS S3 offloader
  • Implemented 3rd party SSO SAML2.0/OAuth2 support
  • Co-wrote back end architecture for new domain using federated Apollo GraphQL services
  • Acquired solid understanding of Mongo aggregations (and their verbosity...)
  • Built services integrating with 3rd party ITCS systems
  • Built several NodeJS and Rust apps running on our in-vehicle device
  • Built IFTTT-like service for sending commands to vehicles
  • Maintained and improved public WebSocket server; exposing live data streams
  • Performing job interviews
  • Organizing hackathons
  • Organizing and performing 1 on 1's and feedback sessions
  • Lots more that I can't remember
