• Designing and implementing systems that identify fraudulent / unwanted gig-worker behavior to improve bottom-line growth.

Birmingham, AL, US

• Focus Area: Gig-worker Pay
• Developed a new paradigm for gig-worker effort measurement based off geo data; thereby lowering the variance in self-reported effort and establishing more reliable ground truths for both modeling and reporting.
• Identified fraudulent behavior by geo-fencing package drop-offs and developed code to operationalize the logic, thereby saving at least 2 weeks of engineering work for the team
• Ideated, trained and productionalized a machine learning model to estimate gig-worker effort, thereby significantly increasing accuracy, lowering engineering maintenance and unlocking future feature engineering.
• Got buy-in from varied group of business stakeholders by creating a pitch deck to highlight benefits and accuracy improvement of the above-said model
• Enabled faster launch of above-said model into production environment by implementing exhaustive testing and impact analysis that enabled a 2-day dark mode testing, a vast improvement from the usual 10+ days dark mode.
