Torre Aburra Smart Building Retrofit

Lead the BMS/IoT retrofit of a 22-storey government tower in Medellin under Gobernacion de Antioquia. Defend the OT/IT network architecture against the CISO, rebuild the energy-savings business case under honest control-envelope attribution, negotiate the cost-and-scope reset with vendor and owner under Decreto 1082, and present a defensible board paper before the 10 June 2026 deadline.
