Summary
🤩
Rockstar🎓
Top SchoolFachrin Nasution is a Senior Product Engineer based in Berlin with a decade of engineering experience and seven years focused on designing and operating large-scale distributed systems serving millions of users. He excels in backend architecture and data pipelines, routinely leveraging Go, Kafka, PostgreSQL/BigQuery, gRPC and cloud-native tooling to deliver robust, multi-tenant solutions for fintech and consumer platforms. At Upvest he built resilient corporate-action and tax-exemption systems integrating disparate data sources and formal message standards, and earlier roles at Gojek, Tokopedia and Delivery Hero show a pattern of shipping measurable product outcomes—lower cancellations, faster consumers, and higher conversions. He’s pragmatic about engineering practices, introducing DDD architectures, CI-attached Kafka testing, and observability improvements that raised team productivity and monitoring fidelity. Colleagues would call him “AlwaysInBeta”: curious, hands-on, and comfortable turning complex domain rules and financial formats into production-grade services.
