Dennis is currently a Member of Technical Staff at Magic, leading the Protocol team as a Chain Architect. At Magic, Dennis is designing and implementing Magic's decentralized OAuth protocol called Magic Newton, with the goal of achieving a universal access on all dApps across different chains with a unified identity and liquidity.Prior to Magic, Dennis was a Staff Engineer at Alchemy, building the AccountKit: an open-source aa-sdk (https://github.com/alchemyplatform/aa-sdk) that handles all the complexity of ERC-4337 under the hood to abstract out the complex account abstraction infrastructure stack for developers with highly performant Rust-based ERC-4337 bundler developed in-house (https://github.com/alchemyplatform/rundler).Prior to Alchemy, Dennis has been building layer 1 EVM blockchains since 2018, mainly Harmony Protocol (https://www.harmony.one/) and Klaytn Blockchain (https://klaytn.foundation/), working on architecting and developing highly optimized, BFT-based public blockchain infrastructure that achieve 1-second finality and extremely high TPS for real-world enterprise level use cases with lower cost of running Blockchain Applications (dApps) and lower barriers of entry for end-users.Dennis comes from the distributed systems and machine learning background from Facebook with Computer Science degree at Stanford University.Dennis started his career at Meta after studying Computer Science for undergraduate studies at Stanford University. At Meta, he spent four years building, growing and leading the Facebook Media Platform team with his focus on distributed systems and AI computer vision. Dennis holds a Bachelor of Science with Honors from Stanford University where he studied computer science with focus on artificial intelligence and deep neural networks under the advisory of Professor Andrew Ng.

Founding Member & Core Protocol LeadHarmony 2018 - 2021Mountain View, Ca, UsAs one of the founding members of Harmony Protocol, I led the Core Protocol Engineering building the core infrastructure of the open, decentralized network.Specifically, I conducted research and development of the decentralized sharding and consensus mechanisms that power the fundamentals of the protocol for its high-throughput, low-latency, and low-fee consensus platform designed to power decentralized economies of the future. I worked on the full stack layers of blockchain infrastructure, from state pruning, fast state sync, proof of stake, node RPC api, etc. (https://github.com/harmony-one/harmony)As the protocol matured, I focused on the research and development for the interoperability and layer 2 rollup architectures, mainly the zero knowledge proof technology as the key component for both. As a result, Harmony Protocol launched its trustless Horizon bridge connecting Harmony with Ethereum, Binance Smart Chain, Bitcoin and more that exerts high scalability with strong security using zero knowledge proofs, and further developed the protocol as the cross-chain interoperability layer 2 on Ethereum. -
