Top SchoolNilesh Mahajan is a seasoned software leader and founder with 12 years of experience building cloud-native data platforms and developer-focused products. He’s currently splitting time between leading Onehouse’s Cloud & SaaS platform as a founding engineer and co-founding Next9.ai to radically improve engineering on-call effectiveness, while also running a developer-tutorial startup, Walkthrough. His background spans high-scale roles at Uber and eBay, where he built real-time data systems and resilient edge streaming gateways, giving him deep expertise in distributed systems, streaming, and platform reliability. Trained at Stony Brook and with early systems work at IBM, he combines research pedigree with hands-on product engineering and a knack for turning complex infrastructure challenges into practical, developer-friendly solutions.
