I build blockchain, AI agent, and full-stack products that drive DeFi utility and business impact.
VietnamWhat I'm looking for
At Krystal–Kyber Group, I build wallet extensions, EVM-focused dApps, smart contracts, AI agent systems, launchpads, and blockchain automation bots. My work supports products spanning 2 to 10 EVM chains, including Krystal Vault, V4Utils, subscriptions, and liquidity offerings.
I reduced GCP infrastructure costs by 15% and built an SEO-optimized Krystal landing page that achieved an 88/100 performance score and 100/100 best-practices, SEO, and accessibility scores. I also contributed to products with $10M AUM and $700K vault TVL.
I'm a lifelong learner focused on blockchain and AI, especially using AI agents to improve productivity. I’m looking for an enterprise where I can apply my knowledge to strengthen the team, grow together, and create benefits for everyone.
