Summary
👤
Senior🎓
Top SchoolGergely Timar is a seasoned engineering leader based in Sunnyvale with nearly a decade of senior-level experience delivering internet-scale data and advertising systems that handle tens of thousands of requests per second and petabytes of data. As Senior Director of Engineering at Roku and previously at Verizon Media/Yahoo, he has built and transformed DMPs, attribution platforms, DSP optimization engines and analytics backends that drove tens of millions in revenue under strict SLAs. He blends strategic vision with hands-on technical depth in modern C++, Java and Python, shipping ML-driven solutions in production using TensorFlow, XGBoost and low-latency inference stacks. Gergely’s expertise spans the Hadoop ecosystem and specialized low-latency stores like RocksDB, and he has led teams through two acquisitions while maintaining velocity and engineer morale. He pairs deep domain knowledge in programmatic advertising, campaign optimization and privacy (GDPR) with a research-rooted background (PhD-level work in neuromorphic/vision systems), which helps him bridge data science and production engineering effectively. An operator who also prototypes core infrastructure (RPC libraries, real-time reporting APIs and sketch-based aggregations), he is equally comfortable setting product strategy and diving into algorithmic performance tuning.
