A selection of things I've built, from encrypted social apps to on-chain games and data indexers. More of my code is on GitHub.
An end-to-end encrypted social feed on Sui, where only the author and approved followers can read a post.
Social feeds usually trade privacy for reach: the platform can read everything. Encrypted_X encrypts posts on the client with Seal before they leave the browser, so only the author and the followers they approve can decrypt them. The feed still feels like a normal social app, with a React frontend and a real-time backend.
A fully on-chain multiplayer strategy game on Sui and Walrus.
Players build a criminal empire through strategic decisions, territory control and resource management. All of the game’s state lives on-chain.
An event-driven indexer for on-chain data, with cached REST APIs and live WebSocket updates.
On-chain events are picked up by idempotent queue workers built on BullMQ, so retries never double-count. The data lands in PostgreSQL and is served through Redis-cached REST APIs, with live updates pushed over WebSockets. It runs in Docker behind an Nginx TLS reverse proxy, with CI on GitHub Actions.
A decentralized document-signing system with trustless, verifiable digital signatures.
Signing a document usually means trusting a company in the middle to hold the record. WalSign removes that intermediary: anyone can verify the signatures without going through a central service.
A minimal DAO where token holders propose, vote on and execute ETH transfers from a shared treasury.
On-chain governance kept to its essentials: token holders create proposals, vote on them, and execute the approved ETH transfers from a shared treasury. Written in Solidity and deployed on the Base Sepolia testnet.
A closed-cycle token system for controlling and tracking real-world financial incentives on-chain.
An AI-enabled impact calculator for the UN Health4Life Fund that estimates Healthy Life Years gained from health interventions.
Built for program officers and impact assessors, it calculates Healthy Life Years (HLY) gained from global health interventions. It ships with process-flow and worked-example documentation.
A cross-platform desktop app with 13+ interactive Canvas-based modules.
Built with Electron and packaged with electron-builder for Windows and macOS.
