Top SchoolJason Barmparesos is a software engineer with 10 years of experience, currently based in Warsaw and building production systems at Grass Valley. He has strong systems and C++ background from ByteDance, where he helped design and optimize a distributed, large-scale approximate nearest-neighbor database (HNSW) and achieved a >10x search throughput improvement. Jason pairs that low-level performance work with practical tooling—authoring a Rust/Tokio importer and internal Python/React debugging tools—and earlier contributed to distributed Go pipelines for video deduplication. His background includes HPC tooling at Arm and graduate training in electrical and computer engineering, reflecting a blend of performance engineering and practical product focus. Notably, he moves comfortably between languages and domains, from C++ and Rust to Go and TypeScript, making him effective at shipping efficient, cross-stack solutions.
