# Mingjun Zhao **AI Agent Engineer · Security Tooling · Execution Infrastructure** I build the systems that let AI agents act: reliable tool use, governed execution, and domain-specific automation that can move from a demo into a real workflow.

Selected work

SecBot An authorized security-testing workspace with a NestJS backend, Ink terminal UI, MCP integration, and security-focused tool modules. `TypeScript` `NestJS` `MCP`	ExecGo An agent-first execution layer for validated, cancellable, observable, and recoverable actions, with DAG scheduling and pluggable executors. `Go` `Runtime` `Infrastructure`
MPH-Agent A domain-specific agent that turns natural-language COMSOL requirements into complete simulation models across geometry, physics, meshing, studies, and solving. `Python` `COMSOL` `Domain Agent`	Damn Agent A Chinese learning resource for understanding, building, and evaluating AI Agent systems. `Documentation` `Agent Engineering` `MDX`
iammm0 My engineering profile: a collection of open-source work across AI Agent systems, security tooling, execution infrastructure, and applied automation. `Open Source` `AI Agent` `Engineering Profile`

Other work

execgo-runtime — A process-level data-plane runtime with persistence, cancellation, resource policy, and artifact auditing.

Engineering focus

Area	What I care about
Agent systems	Tool calling, planning loops, context, memory, MCP, and multi-agent coordination
Execution	Task contracts, DAG scheduling, retries, timeouts, cancellation, and recovery
Safety	Authorization boundaries, sandboxing, resource policy, auditability, and human control
Product engineering	Clear interfaces, useful defaults, operational feedback, and documentation that helps people ship

Background

I started from applied physics and moved into software engineering through scientific computing, full-stack systems, and increasingly systems-oriented AI Agent work. That background still shapes how I build: define the model, make the constraints explicit, and verify what happens in the real system.

中文简介：我从应用物理出发，逐步进入软件工程，当前专注于 AI Agent、安全工具与执行基础设施。比起展示“会什么”，我更关心系统能否被验证、被控制，并真正完成任务。
