- Spearheaded a pioneering project focused on building a distributed asynchronous event-driven architecture using SQS, resulting in a substantial reduction of post-checkout cancellations from 2.8% to 1.6%. The implementation significantly enhanced the overall diner experience, reduced care contact, and minimized free giveaways.- Integrated Kinesis data streaming into Grubhub's data platform to enable efficient tracking of diner cart activity. Collaborated closely with the data-platform team to store object blobs in S3 and developed Spark jobs for seamless data loading into Hive tables using Avro schema.- Leveraged the power of Presto for data querying, leading to an impressive 75% reduction in RCA dev-hours. This optimization accelerated data analysis and improved team productivity.- Acted as a key representative of the order-taking system during the development and testing of a multi-service product initiative. This initiative revolutionized Grubhub's partnership model, allowing restaurants to serve diners beyond their self-delivery boundaries. The outcome was an additional 18% increase in daily orders for participating restaurants, resulting in a remarkable +45k orders/day.- Successfully onboarded and integrated 15k pilot restaurants onto Grubhub's delivery platform, expanding the company's reach and solidifying partnerships with local establishments.- Designed and implemented re:Dash and Datadog dashboards, leveraging tools like Splunk, to monitor critical metrics and key performance indicators (KPIs). These dashboards provided invaluable insights and streamlined the debugging and data analysis processes.- Developed highly-available and fault-tolerant features for the checkout platform, with a strong focus on operational excellence. Conducted thorough capacity planning, defined Service Level Objectives (SLOs), performed comprehensive load testing, implemented dynamic auto-scaling, and enabled adaptive load shedding to ensure optimal.

- Revamped payment engine, enabling seamless checkout experiences and increased conversion rates by offering diverse payment options. Remodeled architecture, optimized workflow, and integrated new gateways for an efficient & flexible payment processing. Resulted in enhanced customer satisfaction and a 12% boost in conversion rates.- Led cross-functional team in developing the high-throughput Risk & Payment orchestration engine (RPOE). Employed advanced technologies and best practices to ensure low latency and high performance. Enabled secure and efficient processing of large payment volumes, adhering to stringent security standards.- Effective risk management & fraud prevention measures in RPOE contributed to a $10 million annual improvement in net profit. Reduced false positives, minimizing revenue loss from legitimate transactions being flagged as fraudulent. Recognized across the line of business for significant positive impact on financial performance.- Implemented rule-based techniques and adaptive machine learning algorithms to identify and mitigate fraudulent transactions. Continuous analysis of patterns and adaptive fraud prevention capabilities resulted in a remarkable decrease in the fraud reject rate, enhancing trust and confidence of customers.- Utilized analytical backtesting techniques to conduct in-depth analysis of complex fraud schemes. Fine-tuned fraud prevention algorithms using internal logistic regression models, ensuring continuous improvement in fraud prevention capabilities and a secure platform for customers.- Created the award-winning Hacker-Flyer web application as a personal hobby project. Leveraging technologies like elastic search, Spring Boot, Google Maps & Ractive.js, enabled users to search flights based on defined budgets using the last 2 days of data. Received Popular Choice award in 2018 Hackathon. Enhanced app with additional options and views for categorized location results, further improving its usability and value.
