Architected and built features for Uber Works, which connects businesses to workers and workers to opportunities. Worked on the mobile app and internal ops web app, and was the lead engineer on analytics capture.- Launched a version of the scheduler system that sharded on types of tasks, reducing load on any single instance. Allowed the business to scale and support 50x the previous load.- Led the design of and built a tool that allows the operations team to pay workers’ cash incentives via integrating with vendors’ payment API, reducing the workflow to take a few seconds instead of days.- Implemented push notifications that increased workers engagement with the app (to record timesheet data), reducing time that ops spend on correcting timesheets times by 30%.- Introduced ETL diffing mechanism that synced analytics data tables in a few seconds instead of 25min+, additionally leading to a decreased cost expenditure on database operations from $1240/mo to $280/mo, a reduction of 78%.- Migrated a core legacy architecture to a scalable model allowing for a 20% load reduction on scheduler, and speeding up related feature development (for example, a task that would take 2 weeks is reduced to 1 week). The new architecture simplified analytics across related models.(NodeJS, React/Redux, React Native, Python, API, GCP, Firestore, Segment, Amplitude, Sentry, Logz.io)

Built systems to drive customer acquisition for Drift’s web chatbot, leading to $700k+ revenue in 2018 and $91k/MRR revenue impact per engineer. The systems detected incoming signals of buyer intent (to purchase Drift) and automated outreach. Projects I’ve designed and built contributing to revenue:- System that searched for potential customers amongst company-authored LinkedIn posts.- Automated LinkedIn messaging, outbound to potential leads on behalf of Drift’s sales reps.- Webhook to ingest real-time install/uninstall events of competitors’ tools from scraped websites.- System to detect accounts approaching renewal of competitors’ tools, who could then consider Drift as a vendor.(Java, SQL, Javascript, Python, React/Redux, API, MySQL, Kibana, AWS, Segment, Amplitude)
