Hi, I'm Dino — my full name is Trinh Ngoc Khang, and I'm a Senior Blockchain Developer based in Hanoi. I've been in the software industry for over six years, and for the last four-plus years I've focused entirely on blockchain — covering smart contracts, backend, security, and system design.

Right now I'm working remotely at Friend Space, a Web3 social-token platform on Base where creators tokenize their "shares" and users can trade, stake, and chat with integrated DeFi. I own both the smart contract layer and a big part of the backend. On the contract side, I designed and shipped the full on-chain stack — bonding-curve ERC-1155 tokens, per-creator staking, cross-chain fund management via deBridge, and a fee and room configuration layer, all using upgradeable proxy patterns. The contracts passed a third-party AstraSec audit. On the backend, I build the API in Hono, the real-time WebSocket stack with Kafka and OpenSearch, and a set of AWS Lambda cron jobs for things like points, PnL, and portfolio snapshots.

Before this, I spent about three years at BlockPixels building NFT marketplaces, a multi-chain indexer storing 3.5 terabytes of on-chain data, and a token bridge using Axelar. I got our contracts to a 10 out of 10 Hacken security score, which taught me a lot about gas optimization and writing safe Solidity.

Earlier, I was a Technical Leader at Sotatek, the biggest blockchain outsourcing company in Vietnam, where I worked on aggregator DEXes, governance DEXes, bridges, and NFT platforms, and mentored newcomers on Web3.

What I enjoy most is owning a feature end-to-end — from the smart contract up to the API. I'm always looking to learn, and I'm especially interested in security.
