Work Experience
Principal Software Engineer
2021 - PRESENT
AlphaSights
- Wrote custom Ember.js code to allow developers to migrate from Ember.js to React in a progressive way. This was done by creating a custom Ember.js component and customizing Ember's dependency injection system.
- Developed the plan and started rewriting a 12-year-old app. The challenge was to rewrite the actual software and find a scalable process where other engineers could collaborate without interrupting new feature development.
- Mentored and taught younger engineers to learn React, software best practices, testing-related tools, continuous integration pipelines, and how to be effective within the company.
- Led the front-end internal community by hosting the weekly meetings and getting everyone in the group involved in the wide range of front-end related topics.
- Created a Google Workspace add-on. Led the UI design, wrote the back-end code using Node.js, and implemented the add-on UI using the Google Card-based interfaces. I also set up the Google Cloud and CI pipeline required to test and deploy.

- Helped implement software for managing surveys to replace spreadsheet-based workflows. The highlight of this job was the integration with third-party survey providers such as Qualtrics.
- Created a read-along audio player using React and VTT files which would show transcript information in sync with the audio as it plays.
- Helped create the client portal website, which shows clients their assets and past interactions with the company. The portal was written using Spring Boot, Kotlin, and React in the front end.
- Improved the Ruby on Rails test suite by implementing parallelization and removing tests dependencies.
- Upgraded RSpec tests by reducing the number of files loaded and refactoring into a more readable format using one-liner syntax and expect API.
