Kansas City Software Engineer

I’m a Kansas City full stack software developer with more than 20 years of experience. I taught myself to code around the year 2000 and supported myself with the code I wrote as my own boss for four years, then took a corporate job. Today I’m a Senior Software Engineer at Shamrock Trading Corporation in Overland Park, just across the state line in the Kansas City metro, and I still write code on the side. Here are the tools I currently work with (there’s a longer list at the bottom of this page with everything I can remember touching):

  • JavaScript (TypeScript)
  • C#
  • Python
  • React
  • React Native
  • PostgreSQL
  • Electron

Certifications

A few recent ones:

  • AWS Certified Developer, Associate (Amazon Web Services, 2025)
  • Claude Code in Action (Anthropic)
  • Introduction to Agent Skills (Anthropic)
  • Introduction to Subagents (Anthropic)

Availability

Freelance

I do pick up side work and consulting jobs every now and then. I am a full stack developer in multiple languages and databases. I’ve been doing this since 2002.

Recruiters

I currently am a Senior Software Engineer. That being said, the benefits where I work are great and I like the work and the people. But if you think you have something better, connect with me on LinkedIn. I rarely answer phone calls from numbers I don’t know.

Selected Projects

A few things I’ve built that I’m happy to point at:

  • Numerai: placed 8th out of 250 competitors in the Numerai stock-market tournament using deep learning.
  • Moodify: a sentiment-analysis app built at the 2015 Hack Midwest hackathon.
  • Zen Notebook: a cross-platform note-taking app (Node, Cordova, AngularJS, Laravel).
  • Door and Window Parts: a Zen Cart ecommerce site.

Code Repos

Here is where you can find some of my code. I realize I don’t have a portfolio section, but I am not a designer. I’m a full stack developer and have spent part of every job in the frontend. I write code, so here’s some code:

Coding Skills (the rest of them)

I am a full stack developer who has worked with many stacks.

On My Side Projects

  • Any desktop apps use Electron
  • Any phone apps React Native
  • I usually use Python Flask to create a REST API
  • I use ReactJS on the frontend to render the site
  • I use MySql/MariaDB or PostgreSQL depending on the platform and use case
  • I use Python for any heavy data processing, backend processes, and machine learning
  • I use Docker everywhere I can

Data Skills

Along the way, I learned a lot of SQL, NoSQL and other various ways of handling data.

Databases: MySQL · SQL Server (TSQL and procedures) · Oracle (PLSQL, packages, and procedures) · Postgres (my preferred database for many things) · MongoDB · Redis · Memcache · Neo4J · Hadoop · ZeoDB (I learned it, so it’s here) · Filemaker (I was forced to learn it, so it’s here)

I am putting Machine Learning here because it seems to fit:

Machine Learning: Natural Language Processing · H2O · Theano · Keras · TensorFlow · Pandas · Scikit Learn · Numpy · Scipy

Ops Skills

Ops: Linux Administration · Apache · Nginx · Docker · Puppet · TravisCI · Jenkins
