• Built self-serve statistical power analysis tool using AWS Lambda, an internal power analysis Python module, and Snowflake into the core Golang experimentation service, enabling more rigorous and scalable experimentation by reducing analysis turnaround time from days to minutes

• Built scalable data pipelines in AWS Glue using a custom markup language interfacing with PySpark to analyze tens of millions of experiment exposure events.

• Improved operational reliability through on-call incident response— tuned AWS SQS parameters to reduce downstream user-targeting service API calls by 50%, and refactored Redis-based exposure event caching to align with best practices.

• Automated metric creation for experiment owners by leveraging the GitHub API to generate pull requests, eliminating manual workflows and accelerating experiment setup.

• Enabled data-driven product decisions by supporting internal teams with experimentation guidance and platform expertise via dedicated support channels.

• Implemented real-time logging for tiles viewed in Chime’s Offers Marketplace using React Native, Segment, & Ruby, enabling analytics on Chime’s mobile app for ~20,000 users/day

• Developed a programmatic security awareness campaign using Python, Pandas, & RESTful APIs that engages with Chime members who have interacted with Chime social media accounts & won first place in Chime's Respect the Rules category out of 81 hackathon project submissions

• Wrote Python script using Pandas & RegEx to extract Chime member usernames from social media interaction data through Sprinklr API & export them in JSON format as part of Chime hackathon project

• Created reusable template screen with server-driven components using React Native, Ruby, & GraphQL, allowing Chime to reach dormant users without latest app updates

• Developed full stack app enabling configurable, synchronized bug tracking between Jira and Bugzilla

• Designed REST API endpoints and SQL schemas

• Built and tested REST API using Express, Node.js, Postman

• Drafted mockups and implemented sync configuration UI using Angular and Clarity Design System
