Hi, I’m Andreas 👋

Senior software engineer with a background in theoretical physics, specializing in performance-critical systems, algorithms, and numerical software.

Focus areas

• Modern C++ (C++17/20) — algorithm engineering, cache-aware data structures, profiling, benchmarking, and correctness-driven design
• Graph algorithms & numerics — both theoretical foundations and practical, large-scale implementations
• Go — graph algorithms, numerical libraries, and initial work on distributed-systems-adjacent tooling
• Python — analysis, tooling, experiments, and ML-adjacent prototyping

Selected open-source work

• NetworKit (C++) — graph algorithms, planarity testing, and substantial performance optimizations; extensive testing and benchmarking
• Gonum (Go) — graph algorithms and numerical special functions (e.g. dilogarithm Li₂), with benchmarks and performance analysis
• Personal repositories — algorithm implementations, performance experiments, and systems-programming playgrounds
