AI Engineer & Senior Full-Stack Developer

I combine 20+ years of full-stack engineering with modern AI workflows, LangGraph multi-agent architectures, Harness Engineering, CDD/SDD, and strict guardrails to build and modernize reliable business systems.

20+ years building enterprise software, currently building LangGraph/LangChain agentic tooling, Harness Engineering PoCs, AgTech tracking systems, and modern ERPs.

About Me

With over 20 years in software development, I specialize in AI Engineering and modern architectures. I construct high-trust AI agent workflows using frameworks like LangChain, LangGraph, LangSmith, n8n, and FastMCP, validated with strict guardrails, evaluation pipelines, and Harness Engineering test suites. I also modernize legacy systems using .NET 9, React, and cloud architectures.

Currently focused on Constraint & Spec-Driven Development (CDD/SDD), Harness Engineering, and stateful agent graph orchestration using LangGraph and LangSmith. Active work includes internal AI developer tooling, Proofs-of-Concept for automated eval harnesses, an enterprise ERP, and an AgTech Cow Monitoring telemetry platform.

"Leveraging AI and best practices to enhance code quality and accelerate development cycles without compromising reliability."

Frequently Asked Questions

A quick overview of how I usually help teams evaluate, build, and modernize software.

What kind of AI automation projects do you build?

I build practical AI workflows that connect LLMs, N8N, MCP, APIs, business data, and human review steps into reliable automation.

Can you modernize an existing .NET Framework application?

Yes. I help teams assess legacy .NET systems and move incrementally toward .NET Core, .NET 9, React, cloud-ready architecture, and safer deployments.

Do you work with existing teams?

Yes. I can work as a hands-on developer, modernization consultant, technical lead, or AI automation partner depending on the project.

Can you help evaluate whether an AI workflow is worth building?

Yes. I can review the process, data, risk, cost, and expected outcome before implementation so the project starts with a practical plan.
