Professional Summary
Owner of HammerAgent, an AI-assisted modem debugging system built on QGenie SDK/model integration, agentic tool workflows, domain-specific RAG, evidence score, and rule-driven log analysis for RF, Digital, and MAC UL debug.
Architected Hammer/HammerAgent as an E2E triage platform with FastAPI web portal/orchestrator, local pipeline runner, parser/analysis engine, cross-layer correlation, deterministic verdict gate, advisory AI layer, feedback store, and continuous learning loop.
Staff RF Embedded Software Engineer with deep experience in 5G modem RF software, Tx architecture, RFFE control, product bring-up, customer escalation, and Hexagon & ARM IU processor development.
Work Experience
Qualcomm — Staff RF Software Engineer
Dec 2024 – Present · Pudong, Shanghai
Created HammerAgent, an end-to-end AI-assisted debugging agent for RF, Digital, and MAC UL analysis, integrating QGenie SDK/model access, in-house embeddings, skill/tool orchestration, evidence extraction, and human-in-the-loop diagnosis.
Co-architected Autologparser from parser automation into a measurable closed-loop triage architecture with QUTS/QXDM parsing, opcode registry, QTRACE/IQ capture, SQLite artifacts, FastAPI orchestration, dashboard telemetry, feedback ratings, and email/report delivery.
Drove early-stage design and technical proposals with RF System and Modem System teams for TxAGC evolution, uplink power limiting, envelope expansion, and UL enhancement from concept to bring-up readiness.
Designed and debugged RFFE control behavior across PA, PAPM, XSW, ASM, and tuner paths; served as point of contact for DSDA Tx and Intra-CA Tx feature design, triage, and customer support.
