Experience
CRM Integration Into Platform Product
I designed and built systems that retrieved data from customers' Hubspot and Bullhorn Staffing instances and synced the data onto the platform product. Already in use by more than 30 different customers, with data synced at intervals of 5-10 minutes and millions of pieces of content daily. These customers were specifically onboarded after these integrations were made available.
In addition, I added new features to the previously existing Salesforce integration; some of these included syncing over broader scopes of data and allowing for more customer customization.
I was the owner of all these implementations, meaning I was in charge of identifying areas of improvement, monitoring the logs for any spikes and bugs, triaging customer bugs, refactoring code whenever necessary, and expanding unit and E2E testing periodically.
