Summary
🤩
Rockstar🎓
Top SchoolPremkumar Janagarajan is an engineering team lead with 9 years of experience building and modernizing high-throughput distributed systems, currently driving AI-driven development practices for Betsson Group’s Campaigns & Rewards domain. He led a Kafka- and Kubernetes-based migration, introduced Microsoft Orleans actor patterns to scale systems processing thousands of real-time transactions, and created KAIzen—an AI layer for Agile that boosted his team’s flow efficiency from 32% to 85% by replacing stories with structured specs and Copilot agents. Comfortable across cloud-native infrastructure, event-driven architecture, and domain-driven design, he also contributes to Proto.Actor’s .NET implementation, demonstrating practical actor-model and protobuf expertise. Based in Linköping, Sweden, he combines hands-on backend craftsmanship with a trader’s appetite for automation—having built automated options-trading systems indexed in Elasticsearch—so he focuses on changing what teams feed AI to accelerate delivery rather than reorganizing around it.
