Sebastian Gruza

Graph databases, distributed systems, blockchain analytics. Java/Spring since 2014, graph theory since 2013. Warsaw, remote. More at gruzalab.pl.

Apache HugeGraph. I validate the HStore/PD backend, the Helm chart and the client toolchain on my own clusters and fix what I find upstream: reproduce, measure against a reference, fix, measure again. Six fixes merged in September 2026, three PRs and the Rust roadmap groundwork open. The lab, the harnesses and every finding live in hugegraph-validation.

Elsewhere. TspSolver: GPU-accelerated Traveling Salesman solver.
