High-Velocity Issue Triaging • TDD & 100% Green CI • Soroban Smart Contracts • Next.js 15 & gRPC Distributed Systems
I am a Senior AI Systems & Distributed Architecture Engineer with over 9 years in the open-source and software engineering ecosystem (active on GitHub since 2017). I specialize in designing self-healing autonomous multi-agent systems, deterministic tool-calling workflows, and high-throughput distributed microservices.
Whether orchestrating autonomous agents with strict TDD feedback loops, tracking elusive race conditions in distributed microservices, hardening Rust/Soroban smart contracts, or building high-performance 60FPS WebGL interfaces, every system I build is designed for correctness, deterministic reliability, and long-term endurance.
- 🔍 Root-Cause Analysis (RCA): AST symbol graph analysis and invariant reasoning to isolate subtle regressions and architectural bugs within minutes.
- 🧪 Strict TDD Methodology: Every fix starts with a failing regression test to prove the bug, and ends with 100% green tests on real CI environments.
- 🛡️ Chaos Fuzzing & Red-Team Audit: Patches and services are stress-tested against 25+ synthetic edge-cases and audited on 5 security axes before deployment.
- ⚡ Ultra-Fast Turnaround: Instant issue triaging, rapid turnaround, and transparent communication across open-source maintainers worldwide.
- 📍 Location: Vietnam 🇻🇳 (Collaborating with global teams, open-source organizations, and Web3 ecosystems)
