Implemented OAuth 2.0 authentication support for Ramp within an authentication micro service using a Rails service adapter pattern with custom access token extraction, refresh token logic, and REST endpoints for frontend authentication, status retrieval, and token revocation.

Constructed a Ramp webhook service layer utilizing a service class pattern to wrap API endpoints with preemptive access token refresh, orchestrating the full webhook lifecycle including challenge token verification and multiple webhook event support, unblocking 12 downstream integration projects.

Architected technical design of white labelling feature that leveraged the AWS API by integrating the SDK into existing controllers to apply email template customizations and generate DNS records to enable custom sending domains with DMARC compliance. The feature maintained critical app support and created 39 upsell opportunities.

Maximized product stickiness with custom integrations created on a workflow automation platform that utilizes the public API adhering to RESTful standard. Additionally, designed BI solutions that operate on Looker and are powered by Snowflake as the data warehouse which influenced millions of ARR and churn prevented

Expanded integration versatility by constructing a data streaming mechanism with Sidekiq and services classes to manage imported 3rd-party data that ensures data parity across platforms which led to a 4.4% increase in SOW conversion rates.
