Stoyan Rachev is a Principal Software Engineer with over 25 years of professional experience building and scaling cloud-native systems, most recently shaping tax and compliance infrastructure at Uber and contributing to Kubernetes at SAP. He combines deep hands-on expertise in Go and Java microservices, Kubernetes, and software lifecycle management with proven leadership in building teams and driving large migration programs. At Uber he redesigned tax calculation and fares interactions to achieve near 100% match rates across multiple countries, and at SAP he made notable open-source contributions to the Gardener project for managing Kubernetes at scale. Comfortable moving between architecture and implementation, he has led organizations of ~60 people and repeatedly delivered complex platform initiatives like usage metering and zero-downtime maintenance. Based in Sofia, he balances technical depth with product-focused delivery and a history of speaking at industry conferences. An understated strength is his track record of turning cross-functional migration challenges into repeatable, validated solutions that scale globally.
