Top SchoolPablo Oltra is a systems-focused software engineer with 13 years of experience building cross-platform C/C++ and Python solutions for desktop, embedded and distributed systems. Currently at ClickHouse after helping design resilient ingestion pipelines at Tinybird, he brings deep knowledge of database internals, performance tuning and OLAP workloads. He pairs low-level expertise—drivers, emulators and real-time protocol stacks—with pragmatic engineering: CI/build automation and fast, safe iteration. An active open-source contributor, he’s improved AppImage tooling and core game library internals, and pursues hobby work in compilers and languages like Rust and Zig. Comfortable across Linux, macOS and Windows (and even vxWorks/TinyOS), he blends pragmatic product focus with a taste for low-level craftsmanship and game development. Based in Orihuela, Spain, he’s known for turning complex systems into reliable, maintainable platforms.
