iPhone & iPad LiDAR field scanning of ancient sites across Peru and India

For years, I have been drawn to the monumental achievements of ancient civilizations — the precision of Inca stone masonry in Peru, the sacred geometry of Indian temples, the ingenuity of cultures that built enduring wonders with nothing but human hands and collective vision. These sites are not just remnants of the past; they are living testimony to what humanity can accomplish.
As a tech entrepreneur, I naturally turned to technology to help preserve and share these wonders. Using iPhone and iPad LiDAR sensors, I capture high-resolution 3D scans of archaeological sites during my travels. The goal is simple: create accurate digital records that anyone, anywhere can explore — whether for research, education, or pure curiosity. These scans freeze a moment in time, safeguarding details that weather, tourism, and time itself slowly erode.
