Chief Architect
I previously served as Chief Architect at HEAL Group Holdings, overseeing the technical direction across the organization's portfolio of health-tech companies.
In practice, this was a CTO-level role: setting technical strategy, leading engineering teams, and making architectural decisions that span multiple product lines. The title itself was an honorific, given by the family office's principal — an architect and engineer by training — who chose the term deliberately. In Korean business culture, titles carry meaning beyond the organizational chart, and this one reflected both the nature of the work and the relationship.
Separately, I also served as CTO of HEAL Access, one of the portfolio companies, where I led the engineering team directly.
