Hi, I'm John

I build products,
lead teams,
and ship with AI.

Agentic developer. Fully AI-fluent. Twenty-plus years writing code, half a decade leading the humans who write it. Now I get to do both with a team of agents, and honestly, it rules.

What I'm looking for

An agentic operations role where I help a team actually succeed with generative AI. Setting up harnesses, tightening feedback loops, and pulling the whole org up the curve without losing the plot.

How I work now

I run agents like a small team. On a hot side project I'll push close to a hundred commits in a month: researched, planned, written, reviewed, shipped, with me in the loop the whole way. Claude Code, sub-agents, MCP servers, evals. Daily drivers, all of it.

The interesting part isn't the prompts. (Sorry, prompt engineers.) It's the operations around them. Where to put a harness. How to design feedback so the agent actually learns from the codebase. When to spin off parallel work. When to slow down and demand a human review.

Underneath all of it I'm the same person who likes being in the thick of it: talking to users, debating tradeoffs, pushing things out the door. I believe in servant leadership. Software is easy. Humans are the genuinely hard part, and the genuinely fun part.

EQ > IQ. Agents > alone.

Teams I've led

The most rewarding thing I've done professionally was building, growing, and nurturing a ten-person engineering org. I'd do it again tomorrow.

Movid HEP, out in the wild

At BTE I hired and grew a team of ten developers and PMs from a one-person shop. Movid HEP went from a notebook sketch to a Startup Weekend Hartford 2012 win to a revenue-generating business.

Products I've built

Shipping software since 1999. A few I'm proud of.

Power Inbox Portal

Customer web portal · Sr. Developer

Customer self-service for a high-volume email platform. Lets users manage domains, senders, and deliverability without filing a ticket. ASP.NET on top of Service Bus and Redis.

Soup to Nuts (StN)

Intranet platform · Director of Technology

Operational platform for BTE that ran sales, inventory, and fulfillment in one place. I wrote the first line and the last. Revenue grew 100× over its lifetime.

Movid HEP

Health-tech startup · Co-founder & tech lead

A health-tech startup I co-founded with a physical therapist who hated paper home-exercise programs. Notebook sketch to Startup Weekend Hartford 2012 winner to a real, revenue-generating business.

Tech I reach for

I've used a lot of things over the years. These are today's daily drivers.

  • C#
  • .NET
  • TypeScript
  • JavaScript
  • Vue
  • Blazor
  • PostgreSQL
  • Redis
  • HTML
  • CSS
  • Git

Started on Classic ASP, then PHP/MySQL, eventually C# and .NET. HTML, CSS, and JavaScript have been along for the whole ride.

Nice things people have said

I've worked with John on a number of complex web dev projects. He's a pro and someone I can count on, whether to advise on best approach or dive deep to resolve some obscure bug. An excellent communicator who's always made himself accessible to us regardless of geographic location.

David Buonomo, President & CTO, Blue Atlas Interactive

When I first met John I was surprised by his friendliness, kindness, and tolerance. He's an experienced manager and a talented developer. His management style makes the whole team love him. Any team will benefit from working with John.

Denis Gvozd, Co-founder, Dev Team Inc

John has done an extraordinary job of sitting down with me, analyzing my problems, and using outside-the-box thinking to come up with creative solutions. Other developers stray down the wrong path and waste your money because they don't fully understand your needs.

Ryan Andrew, CEO

John is a talented IT professional who consistently receives positive feedback on his work and has been requested to return to client sites as additional needs arise.

Lisa Drew, Senior Technical Recruiter

Sometimes you come across an individual who really makes you question your own abilities. John is such a person. He produces excellent quality code using the right technology and truly understands the depths of what he's using.
