About

As a Backend Software Engineer with 5+ years of experience, I specialize in designing and scaling distributed systems, APIs, and high-traffic features that drive user growth and engagement. My work spans service migrations, observability improvements, and performance optimization across large-scale consumer platforms. At DoorDash, I serve as a Directly Responsible Individual (DRI) for critical initiatives, including migrating high-visibility DashPass landing pages and multi-plan subscription upsells from a monolithic service into a dedicated growth service. I also focus on system reliability, building monitoring and alerting solutions, and optimizing APIs and data flows to ensure seamless user experiences at scale. Previously at Poshmark, I led the development of Saved Search and personalized messaging, as well as the email service migration to MoEngage, enabling advanced audience targeting and campaign personalization. I also designed backend systems for sweepstakes, promotions, and rebate campaigns, collaborating across product, data, and fraud teams to deliver resilient, user-facing features. I thrive in cross-functional environments, working closely with product, design, and infrastructure partners to translate complex requirements into scalable solutions. Recognized for being detail-oriented and results-driven, I am passionate about building reliable backend systems that empower product innovation and support business growth.
