Head Of Product at Krystal
Hanoi, Vietnam
Summary
👤
Senior🎓
Top SchoolToi Van is a product-focused engineering leader with 11 years building mobile and DeFi products from Hanoi, currently serving as Head of Product at Krystal. He blends hands-on Android and telephony system engineering roots with product strategy, having progressed from Android Lead to Engineering Manager and now product head within the same fast-moving DeFi company. At Krystal he shifted from shipping mobile platforms to architecting automated vaults and farming agent automation, showing a knack for turning complex blockchain primitives into user-ready features. A self-described "product guy trapped in an engineer’s body," he pairs pragmatic engineering judgment with a builder's drive to iterate quickly. His career includes early roles delivering payment solutions and low-level telephony work, which gives him uncommon depth across systems, payments, and mobile UX. Simple and right in approach, he favors clear, practical solutions that scale.
