Performance & Power Analysis
Designed and validated power models for multicore systems. Improved execution performance by up to 34% through system-level optimisation using perf, LIKWID, and Intel PCM.
Distributed Systems Engineering
Built production-grade middleware for Apache Cassandra. Increased throughput by 35% and cut stale reads by 25% through measurement-driven analysis across multi-node clusters.
Linux & Systems Observability
Cross-layer debugging across application, OS, and hardware layers. Currently building ftop — a kernel-level Linux monitoring tool for real-time, low-overhead system observability.
