Summary

I am a Lead Structural Engineer with over 1fifteen years of professional experience in the design, construction, and management of major infrastructure projects across Australia and Singapore. I have successfully led structural design teams and delivered complex transport infrastructure projects under high-pressure environments. My core expertise includes the design and construction supervision of underground metro stations, cut-and-cover tunnel structures, support systems for deep excavations, shallow and deep foundations, and structural assessments of heritage buildings.



At Central Station, I led the construction-phase structural support team, managing design changes, resolving site-based buildability issues, and addressing non-compliance reports in coordination with contractors. I facilitated design coordination meetings and ensured all construction changes aligned with Sydney Metro’s safety assurance processes.
