Ayush Kumar — Software Engineer

I'm a Software Development Engineer at Amazon, driving large-scale technical initiatives across multiple marketplaces and leading product expansions that impact thousands of sellers globally. What I'm Currently Working On: At Amazon, I lead end-to-end ownership of complex projects spanning infrastructure modernization, multi-region product launches, and data engineering at scale. Recently, I spearheaded the deprecation of a legacy service across 3 marketplaces, coordinating 30+ dependencies across 15+ teams and 5 time zones with a 97% completion rate and zero production incidents. I also led the XYZ service expansion to 5 EU marketplaces Ireland, Netherland, Belgium, Sweden and Poland, managing everything from accounting setup to production deployment while coordinating with 6+ cross-functional teams. Technical Impact: • Built full-stack reward systems across NA/FE/EU using React/TypeScript and Java, serving thousands of sellers. • Migrated critical data pipelines serving 50+ downstream consumers, eliminating 40+ hours/month of manual work and reducing errors by 95% • Modernized infrastructure architecture, reducing code duplication by 60% and enabling 3x faster deployments • Independently fixed a 2-year broken pipeline using GenAI-powered debugging (reduced resolution time from 2 weeks to 3 days) My Approach: I thrive on solving complex problems that require both technical depth and cross-functional collaboration. Whether it's architecting scalable systems, optimizing data pipelines, or coordinating with multiple stakeholders across time zones, I focus on delivering measurable impact. I'm an early adopter of GenAI tools, leveraging them to accelerate development by 40% while maintaining high code quality standards.
