Palo Alto Senior data engineer in the Volta cloud team. I own and am the main developer and author of the company's back-end payment processing system, which runs on Volta's DC fast charger network. I also worked extensively with the company's system, which imported data from Salesforce to the Postgres database, and owned/tested a complete refactoring of the system to allow the field operations team to migrate to ServiceMax on Salesforce, enabling cooperation with Typescript/Node through AWS Lambdas.
