## Work Experience

### Senior Software Engineer @ Reddit, Inc.

### Senior Software Engineer @ Tinder
Jan 2020 – Jan 2022
Notable Projects: 
- Collectibles: Created first lootbox system at Tinder as architect and lead. Users can stochastically sample visual icons that relate to their interests, curate them and display them on their profile. Planned and assigned tasks to a team of four engineers, captures Gen Z interest by allowing easy visual self expression and drives user behavior via rewards.
- In App Currency: Designed and lead development of Tinder's first in app currency, a consumable that can be purchased with real money or earned via in-app actions, and then in turn be used to purchase other Tinder products. Multi team project, coordinated with growth team members to onboard them to the revenue codebase. Creates novel economies with different currency flows to influence user behavior and propensity to pay.
- Request Locking Client: Realized a system to prevent duplicate API requests, successfully implemented across revenue services to reduce duplicate purchases and guarantee idempotency in some systems not originally designed to be idempotent. Educated the team in understanding issues around idempotency at scale.
- Partnership API: Architected and developed Tinder's first B2B API, allowing the BD team to make deals globally to bundle Tinder products with third party services. Third parties interact with the API to generate redeemable codes to share with users, or directly grant Tinder products. Interesting project, required coordination between companies to succeed.
