At Realcognita, I lead, mentor, and support the engineering design team, with a focus on quality, efficiency, collaboration, and continuous improvement. I also coordinate with clients through weekly meetings and share monthly team progress reports.

As an HVAC Draftsperson, I designed ducted reverse-cycle air-conditioning systems for Australian residential Class 1 buildings. My work included preliminary heat load assessments, equipment selection, HVAC layouts, duct designs, and installation-ready Bills of Materials.

At ASYA Design, I calculated cooling loads and ventilation requirements using applicable codes and standards, and designed duct systems for commercial and industrial projects. I also coordinated construction documents with other disciplines and reviewed shop drawings and submittals.
