Software engineer in Tampa Bay. I build everything from mainframe batch to AI agents.

What I build

AI-assisted engineering

Software delivered with AI agents writing, testing and reviewing code, and a person accountable for what ships.

Desktop and web apps

Electron and React applications that put a friendly face on complicated systems.

Cloud and containers

AWS and Docker setups you can run on a laptop, test end to end, and trust in production.

Mainframe modernization

COBOL, JCL and MFSORT workloads understood, documented and moved forward without losing what they do every night.

Mainframes to agents

  1. Green screens

    Batch that moves real money

    Copybooks, JCL steps and sort jobs that still run every night. I read them, test them and know what breaks if you touch them.

  2. Desktop and web

    Interfaces people actually use

    React and Electron front ends over hard back ends, built so the next developer can find their way around.

  3. Cloud

    Infrastructure as code

    AWS services and Docker images defined in files, emulated locally, and deployed the same way every time.

  4. Agents

    Teams of AI agents, one engineer in charge

    Agents plan, build and review in parallel. I set the direction, check the work and sign off on every release.

Open for work

I keep my project list short so each one gets real attention. If you've got something in mind, I'd like to hear about it.
