PROFILE
Camillo Bruni
Over two months, Chris Bruni enhanced the google/perfetto repository by building features that improve WebAssembly trace analysis and debugging. He implemented storage and decoding of raw wire bytes for V8 Wasm scripts within the trace processor, expanding the data model and enabling richer inspection of Wasm modules. Using C++, Protocol Buffers, and SQL, Chris updated the InternedV8WasmScript proto, integrated wire byte persistence through V8Tracker, and surfaced decoded Wasm data in the v8_wasm_script SQL view. This work deepened trace visibility, improved debugging workflows, and demonstrated strong skills in trace processing, data modeling, and cross-component integration without introducing regressions.

Feb 1, 2025February 2025: Implemented and stabilized the storage of raw wire bytes for V8 Wasm scripts in the Trace Processor, enabling richer debugging and analysis of Wasm modules in Perfetto traces. The wire_bytes feature was re-landed after an earlier revert to ensure stability. This work strengthens the V8/Wasm tracing pipeline and demonstrates solid data modeling, proto evolution, and debugging capabilities.
