Senior🎓
Top SchoolDmitry Kruglov is a pragmatic CTO and principal engineer with 11+ years of experience building high-performance, low-latency systems and scaling cross-functional teams from seed to production. He combines deep systems expertise—C++ low-latency engines, GPU/OpenCL/CUDA computer vision work and Scala/Big Data pipelines—with hands-on product delivery in Python, Kubernetes and MLOps. At Syzygy AI he grew engineering from 0 to 12 with zero churn, cut time-to-market from weeks to days, and enforces small-batch, KISS-driven delivery underpinned by DORA metrics and TAD/ADR discipline. His background includes architecting 80k‑events/sec pipelines, porting CV engines to arm64, and shipping consumer-facing platforms (CleanBee, SmartMirror) that blend search/recommendation, analytics and mobile integrations. A seasoned debugger and test-automation practitioner, he also contributes practical pytest-mock examples to improve testability. Based in Berlin, he pairs bottom-up leadership with a relentless focus on measurable throughput and operational resilience.
