Summary
👤
Senior🎓
Top SchoolDavid Singer is a seasoned system engineer with over 17 years of hands-on experience designing, deploying, and operating large-scale distributed telecom and infrastructure systems. He has a strong record of automating complex processes (notably turning multi-week HR and project tasks into days) and centralizing logs and monitoring with Elasticsearch, Kafka, and Grafana to enable proactive operations. His work has included merging multi-tenant Kazoo clusters for 200,000+ users, building high-throughput SMS and Class-4 voice systems, and reducing diagnostic times from hours to seconds with custom tooling. A practical problem-solver and former manager, he combines deep Linux/VoIP stack knowledge (FreeSWITCH, Kamailio, CouchDB, RabbitMQ) with a customer-focused support mindset and documented successes in cost savings and operational risk reduction. Based in Port Orchard, WA, he’s equally comfortable leading teams, contributing code (including a public Radix tree Java implementation), and delivering reliable production systems under pressure.
