Network & security engineer · I also build things

I spent more than fifteen years making complex systems reliable. Now I build software with the same discipline.

I still like getting into the weeds. These days that can mean routing and firewalls in the morning, then voice apps, LLM tools, and deployment work at night. AI helps me move faster, but I still own what ships.

Current work

Things I’m building.

I run these myself, from the first ugly sketch through production. Each one started with something I wanted to make less frustrating.

Building01

ProprQuote

Build the quote while you’re still looking at the job.

Talk through the work and ProprQuote turns it into a clean scope, line items, and something you can send the customer. I’m building the whole stack.

Why it exists

The last thing a contractor wants after a full day is another hour at a desk.

Building02

Diagraff

Describe the diagram. Fix it by hand. Let an agent use it too.

Diagraff turns plain English into editable Mermaid diagrams. The web app and MCP server use the same engine, so I’m not maintaining two different versions of the truth.

How it works

Describe it → edit the graph → export it or hand it to an agent.

Building03

Misty Echoes

A voice tarot companion that knows which parts should not be left to the model.

The conversation can be loose. The card draw, session state, and source lookup are code. I don’t let the model quietly invent the parts that should be checkable.

The split

The model talks. The application owns the draw, the state, and the sources.

Background

I’ve been doing this a while.

Pre-sales & network engineering

Learned how to turn a fuzzy request into a network somebody could actually run.

Consulting engineering

Designed and implemented routing, switching, security, wireless, and application delivery for enterprise clients.

Security engineering & project leadership

Led the work from discovery through the change window and stayed for whatever happened next.

Network security & my own products

Keep critical infrastructure running by day; build and operate software at night.

Small public lab

Asciifier

Drop in a photo and turn it into colored text. Change the character set, mess with the levels, and export it. Nothing gets uploaded.

Outside the rack

I like learning things the hands-on way.

I’m also a commercial pilot, licensed skydiver, and rescue-level scuba diver. Those are very different worlds, but all three teach you to prepare, know your limits, and stay useful when the plan changes.
