  • Created a node GraphQL API to support UI layers, generated TypeScript types from RAML for 3rd party APIs, developed suites of automated Postman scripts to validate endpoints E2E, and manually managed PostgreSQL database.
  • Migrated users from in-house DB to Salesforce via Mulesoft, developed tools to verify the integrity of 3rd party APIs proactively, and created custom reporting and UI tools to assist admins with migrating users.
  • Oversaw full-stack development, advised on patterns and best practices, performed code reviews, and maintained a solid unit-testing and integration-testing culture.
  • Created zero-downtime deployment strategy (blue/green), orchestrated frequent deployments, and developed tools to improve productivity around everyday tasks like managing environment variables hosted in AWS S3.

Projects

UI Demo

HTML/CSS
Test driven development
React
Jest
Redux
This is a demo project I completed to demonstrate UI proficiency. It is fully responsive and matches the UX requirements to the pixel. It is backed by React, Redux, and Saga, using Vanilla.js and CSS, and hosted on AWS S3. There are unit tests to ensure functionality, and several optimizations were employed to ensure snappy feedback, like client-side filtering to reduce calls to the server.

React
GraphQL
Application using PostgreSQL, Node.js, and React that served as a platform for developers in the healthcare industry. The system was built as a quick prototype with CRA, which was ejected once the POC phase was complete, and revamped, scalable and maintainable. The UI uses custom React hooks and Tailwind CSS. The Node.js API had an Express router that grew to include GraphQL and interaction with SalesForce CRM as a 3rd party connection. The product was extremely well received by the organization partially because of its capacity to adapt quickly to changes.
