Summary
👤
Senior🎓
Top SchoolEnis Soztutar is a software engineer with 18 years of experience specializing in distributed systems, big-data platforms, and search infrastructure. Based in San Francisco, he has helped build and harden core pieces of Hadoop ecosystems—contributing to Apache HBase, Ratis (Raft), and Phoenix—demonstrating deep familiarity with internals like memstore accounting, RPC/replication, state machines, and snapshot handling. He has driven cloud-native infrastructure at Cloudera for CDP microservices on Kubernetes and now contributes to AI infrastructure at Meta. As a long-standing Apache committer and former founder/consultant in large-scale crawl and indexing projects, he blends research-grade database work with hands-on production engineering. Notably, his open-source commits show both bug-fix rigor and interface-level refactors that improve performance and cross-version compatibility. His background in search, web crawl, and web-usage mining gives him a pragmatic edge in turning massive data problems into reliable systems.
