Founder Thesis
Ray Zhang
HelioVector was founded on the thesis that project owners deserve independent technical-commercial representation. Too many projects suffer from misaligned incentives between vendors, contractors, and owner interests.
Ray brings together field engineering experience, procurement control discipline, and a quantitative decision-making framework developed through both academic training and hands-on project execution.
