Make the trust boundary visible.
I research and build software around light clients, cross-chain systems, and the interfaces that show what a network actually proves.
Experience snapshot
Where I work, learn, and build.
B.S. in Software Engineering · University of Information Technology (UIT) ↗2021 — 2025Education · At UIT, I studied software engineering and used my thesis to investigate browser-side light clients for Substrate chains. That work pulled me from application code into networking, finality, chain specifications, and cross-chain verification.Blockchain Developer Student · LearnWeb3 ↗2023 — PresentTraining · LearnWeb3 was my structured route into Solidity. I used its tracks to build token, NFT, and DeFi exercises, deploy to test networks, and get comfortable reading contract code.Junior Fullstack Developer · Sense ERP ↗2025 — PresentWork · At Sense ERP, I build product features across ASP.NET Core APIs and Flutter screens. The work includes PostgreSQL queries, Redis-backed flows, and fitting new behavior into an existing ERP product.
Experiments
Questions I am testing in code.
All →Kaizen →Early explorationKaizen is my unfinished attempt to sketch an EVM-compatible L2 node in Go. It separates batching, execution, proof, and bridge packages so I can see which design decisions become unavoidable.Axon Cluster →Working prototypeAxon Cluster began with two machines on the same network: one could run the model and one could not. The Rust prototype sends inference requests over a private libp2p network to a machine running Ollama.Voting escrow over a Polkadot light client →PrototypeI built this after getting tired of describing light clients in diagrams. The browser runs Smoldot through Substrate Connect, then uses Dedot for account, transfer, staking, and voting flows.
