Open-Source Contributor & Systems Engineer focusing on distributed infrastructure, application security, and blockchain/Web3 systems.

English Overview · 中文版本介绍

• Active Ecosystem Contributor: 880+ contributions and 66+ merged Pull Requests across production infrastructure, Web3 protocols, and ecosystem tooling over the past year.
• Core Contributions & High-Impact Repositories:
  • Sottara-Labs/sottara: Core contributor with 54+ merged PRs. Substantially hardened production reliability and system safety:
    • Distributed State & Storage: Implemented KV mailbox sync persistence, relay queue depth tracking, and event deduplication windows.
    • Application Security: Enforced cryptographically secure PRNG (CSPRNG) for audit IDs, hardened strict CSP/CSRF policies, and canonicalized payloads with JCS.
    • CI/CD & Gate Enforcement: Hardened E2E test suites (Playwright), bounded job runtimes, and pinned deterministic toolchains (Stellar CLI verification).
  • Perenna-Labs/perenna-contracts: Enhanced WebAssembly (wasm32v1-none) target verification and early CI check gating for smart contracts.
  • AstralDeep/LETS: Implemented strict validation rejecting timezone-naive timestamps prior to canonical UTC normalization.
  • Peer Code Review: Active peer reviewer reviewing and auditing PRs across community codebases, including CalloraOrg/Callora-Frontend and gear5labs/chenpilot-client.
• Platform Badges & Honors: GitHub Pull Shark, Quickdraw, and YOLO recipient.

• Languages: TypeScript, JavaScript (Node.js), Python, Rust (Soroban / WASM)
• Systems & Infrastructure: Cloudflare Workers / Pages, KV Storage, RESTful APIs, MCP Standard
• Application Security & Reliability: CSPRNG Primitives, Strict CSP & Origin Policies, E2E Testing, CI/CD Pipeline Hardening
