Summary
👤
Senior🎓
Top SchoolDenis Shuvalov is a Senior Staff Architect with a decade of experience building cloud-native, data-intensive platforms that process billions of events for companies like Salesforce, Intuit, AppsFlyer and ServiceNow. He blends hands-on performance engineering (JMH, eBPF, Spark/Flink/Kafka tuning) with architecture and team leadership, having led cross-site teams and grown platforms from proof-of-concept to enterprise adoption. A prolific open-source maintainer, Denis created Spark-focused tooling such as spark-sketches and productionized deployment artifacts like druid-docker, reflecting a bias for measurable, reproducible solutions. He’s deeply invested in Data Mesh, real-time pipelines and AI observability, recently exploring agentic AI and evaluation harnesses to quantify model behavior. Colleagues rely on him for clean, evolvable architecture and evidence-driven performance wins—often delivering multi-fold cost and latency improvements that aren’t obvious from design docs alone. Based in Tel Aviv, he mentors engineers in functional patterns and observability to ensure shipped code remains understandable and operable at scale.
