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
