Summary
🤩
Rockstar🎓
Top SchoolGareth Lloyd is a systems-focused software engineer with 15 years' experience specialising in high-performance, low-latency C++ systems and database internals, currently driving performance work at Memgraph. His expertise spans memory layout, custom allocators, lock-free concurrency, interpreter vs JIT design (x86_64, armv8, WASM), and index/Planner optimisations that tangibly reduced memory footprint and query latency. He holds a PhD in Real Time Systems and has prototyped JITs in Rust and explored WASM/LLVM approaches, reflecting a research-informed yet pragmatically engineered mindset. Beyond product work he organizes the ACCU York developer meetup, blending technical leadership with community building. Colleagues rely on him for tackling thorny performance bottlenecks—often by rethinking allocation and cache strategies rather than adding hardware—so his contributions routinely unlock real-world scalability.
