I bring a solid foundation in building codes and regulations, construction technology and materials, structural systems, building services coordination (MEP), and site analysis. I'm well-versed in sustainable and green building design, passive design strategies, energy-efficient systems, and LEED principles, as well as interior design, landscape integration, and urban design fundamentals. Beyond technical skills, I enjoy solving complex spatial, functional, and structural challenges—balancing aesthetics, budget, and buildability. I collaborate closely with structural and MEP engineers, contractors, consultants, and clients, and I'm experienced in project presentations, client communication, design reviews, and preparing tender and permit documentation. I'm committed to continuous learning and staying current with emerging areas like computational design, AI in architecture, smart buildings, modular and prefab construction, and net-zero design. Always open to connecting with fellow architects and design professionals, and exploring new opportunities to create spaces that make a difference. less -
