Work History

Senior Software Engineer

Trend Micro
08.2021 - Current
  • Designed and shipped Windows mini‑filter drivers (C++17) intercepting process, file, and registry events, enabling behavior‑based protection for > 2 M endpoints.
  • Architected multi‑threaded analytics service processing 10 k+ events/sec with < 50 ms latency; improved detection coverage by 23 % QoQ while keeping CPU < 3 %.
  • Implemented TLS‑secured gRPC channel between agent and cloud, reducing false positives 17 % by centralizing ML post‑processing.
  • Authored Python/Perl automation harness executing 150+ daily regressions on vRealize, cutting manual QA hours by 80 % and catching 92 % of production defects pre‑release.
  • Resolved critical customer issues (kernel panics, deadlocks) within 24 h using WinDbg, WPA, and custom ETW diagnostics.

Software Developer

SYMMA Technology
05.2018 - 06.2021
  • Optimized PCB rule‑checking engine (Object Pascal) with computational‑geometry algorithms; reduced layout validation run‑time 35 % on large (> 50 k nets) boards.
  • Built Python‑based license server with RSA‑2048 and SQL backend enabling 500+ concurrent seats and eliminating unauthorized use.
  • Introduced observer and dependency‑injection patterns, shrinking legacy code 12 % and decreasing feature lead‑time twofold.
  • Automated release‑note generation via HTML/JS pipeline, saving the team two developer‑days per release.

Research Assistant (Bioinformatics)

Taipei Medical University
09.2017 - 02.2018
  • Identified novel homology motifs across chimpanzee and human genomes using Python pipelines; findings referenced in department publication.
  • Developed Django portal visualizing BLAST alignments, enabling non‑technical biomedical researchers to explore datasets interactively.
