## Profile

Engineering leader who builds products end to end — from discovery to architecture, delivery and operations — and runs the teams behind them. A hands-on builder long before leading teams; at HMP Master since 2019, rising from mobile developer to Head of Engineering; now also CTO at Sticky and Director of Sticky Vietnam. Startup-built: learns whatever the product needs, then ships it.
