Summary
👤
Senior🎓
Top SchoolDmitry Safonov is a Senior Staff Software Engineer with nine years of professional experience building high-throughput, cloud-native systems across advertising, analytics, and SaaS platforms. He is polyglot across C#, Go, Java/Scala, Python and JS/TS, and has repeatedly delivered end-to-end solutions—from Spark-based data pipelines and Redis/Kafka-backed services to Kubernetes/CDK infrastructure and POS integrations. At Owner.com and prior employers he has driven major cost and performance wins (80% GCP API spend reduction, 3–5x latency improvements, and $700K SMS cost savings) while negotiating and implementing platform-level protections like Cloudflare for SaaS. Comfortable debugging deep low-level issues as well as shaping cross-team architecture, he blends hands-on optimization with product-focused outcomes that measurably improve retention and reliability. A Waterloo-trained mathematician and computer scientist, he’s especially interested in concurrent, data-intensive systems and backend optimization. Not obvious from titles: he often pairs pragmatic cost engineering with technical leadership to turn operational headaches into strategic advantages.
