AI Automation
This section covers the AI engineering work I do alongside my infrastructure and security career. It spans prompt engineering, model training and evaluation, end-to-end AI project development, and intelligent workflow automation using platforms like n8n and OpenClaw.
AI Engineering Overview
I bring the same engineering discipline to AI that I bring to network security and infrastructure.
My AI work sits at the intersection of prompt engineering, model training, project deployment, and automation platform design. I have built self-correcting LLM pipelines, multi-agent distributed AI systems, serverless AI-driven firewalls, and workflow automation platforms using n8n. This is grounded in published IEEE research across AI-assisted security, enterprise AI systems, and intelligent infrastructure protection, and I build working systems that put those ideas into practice.
Prompt Engineering
Designing Reliable AI Interactions Through Structured Prompt Architecture
I design prompts that produce consistent, reliable outputs from LLMs. My approach focuses on structured prompt chains, context management, and output validation with the same engineering discipline I apply to infrastructure work.
- Structured prompt design for complex reasoning, code generation, and analysis tasks
- Multi-turn context management and chain-of-thought prompt architecture
- Prompt evaluation, iteration, and reliability testing for production AI workflows
Model Training and Evaluation
Building AI Systems That Learn, Self-Correct, and Improve Over Time
I train and evaluate models with a focus on practical reliability. My self-correcting LLM research and distributed AI work both come from the same question: how do you make AI systems more dependable in real workflows?
- Self-correcting LLM frameworks with staged reasoning and review loops
- Multi-agent ensemble systems for collaborative local AI problem-solving
- Model evaluation, benchmarking, and performance optimization for specific domains
AI Project Development
From Research Idea to Working Deployment, End-to-End AI Engineering
I build AI-powered applications from concept through deployment. My projects include AI-driven security systems, intelligent data analysis platforms, and health-tech applications that use AI for personalized recommendations.
- Full-stack AI application development with cloud-ready deployment architecture
- AI-driven security systems including serverless intelligent firewalls and threat detection
- Intelligent data platforms like DataMentor for automated analysis and reporting
AI Automation Tools
Workflow Automation with n8n, OpenClaw, and Custom Integration Pipelines
I use automation platforms to connect AI capabilities with business workflows. My n8n deployment and OpenClaw integration work show how intelligent automation can reduce manual effort and improve operational consistency.
- n8n workflow automation for business process orchestration and AI integration
- OpenClaw-based automation for intelligent task routing and decision support
- Custom API pipelines connecting AI models with enterprise tools and data sources

Client & Enterprise Delivery
Completed Works
Real work I have delivered for companies and clients — mail infrastructure, file services, IP telephony, network and cloud architecture, AI automation platforms, and business websites. These are production deployments and live sites, separate from the open-source builds you will find in the Projects section below.
GitHub Highlights & Open-Source Builds
Portfolio Projects
Separate from the client work in Completed Works above, these are my own open-source builds and research systems — cloud infrastructure, network security, AI automation, data workflow tooling, applied AI, and API-driven web apps. Each one is live and shows how I think through a problem.
Infrastructure, Security, Automation, Applied AI, and API Development
I wanted these projects to show more than code. I wanted them to show how I think through problems.
I use these builds to show my thinking in serverless firewall design, Zero Trust security, threat intelligence integration, cloud-ready automation, data analysis tooling, multi-agent AI systems, intelligent workflow platforms, and API-driven web applications. For me, they are one of the clearest ways to connect my engineering work with the research direction behind it.
Google Scholar and Research Pipeline
Research Publications
Published Research Portfolio
This section shows the research direction I am building alongside my industry work.
My Google Scholar profile now includes work across network security, cloud computing, edge computing, enterprise systems, digital forensics, IoT intrusion detection, graph-enhanced CRM, and AI-assisted infrastructure protection. The first-author direction that matters most to me is still physical and cloud network infrastructure security, serverless defense, distributed systems, and security engineering that can move beyond theory.
My strongest first-author work is around cloud security, Zero Trust, serverless firewall architecture, distributed-network resource allocation, and enterprise AI systems.
I have also worked with Dr. Kefei Wang and broader teams across networking, intelligent systems, cybersecurity, and cloud platforms.
The themes I keep coming back to are physical and cloud infrastructure security, network defense automation, edge systems, enterprise analytics, and infrastructure-aware AI applications.

Knowledge Sharing
Blog and Insights
I use this part of my site to explain my work in a more personal and readable way. A resume or a short portfolio card can only say so much, so here I write about my industry experience, client work, GitHub projects, and research in a way that feels closer to how I would explain it in a real conversation.
Why I Write Here
I wanted one place where I could talk about my work in my own words.
On the homepage, I keep things short. In the blog, I slow down and explain what I built, what I learned, what problems I was trying to solve, and why the work matters. I write about network security, Linux and Windows systems administration, cloud infrastructure, client delivery work, applied AI projects, and research that grew from the same real interests.
If you are hiring, this part shows how I think through network security, systems work, cloud infrastructure, and research-led engineering in a more complete way than a resume can.
If you are thinking about working with me, these notes give you a clearer picture of the kind of service work I have done across mail, file, web, telephony, network design, and cloud systems.
If you want to understand my research without reading a paper first, I explain my published work, current submissions, and first-author ideas in simpler language here.
How To Read It
You can start anywhere and follow the part that matches your interest.
I wrote these notes in a simple and direct way because I want the site to feel useful, not heavy. Whether you care most about cybersecurity, cloud systems, client work, AI projects, or research papers, this part of the site lets you go deeper without feeling lost.
