Three decades of writing software at large institutions: central banking, national banks, Fortune 10 healthcare, global manufacturing, federal aerospace, international payment networks. Now taking on direct client work through AppKatz Software.
I work alone. You email me, I write the code, you get the source. No account manager, no junior offshore team, no surprise subcontractors.
What I'm currently shipping
AppKatz Software: a collection of 18 professional Windows desktop applications in C#/.NET, including a voice-AI assistant with RAG memory, a 4K video editor, and vertical tools for contractors, salons, and real estate.
Also building a SaaS business operating system for SMBs: communications, CRM, marketing automation, field ops, and payments on a unified workflow engine. Java services, PostgreSQL underneath.
I ship production code in this stack every week, on my own dime. That's the same stack I'll use on your project.
Stack
C#/.NET for Windows desktop. Java for server-side. PostgreSQL for the database. REST to connect things. Comfortable in regulated environments: banking, healthcare, federal.
What you get
The full working application, the source code, and a perpetual license to use, modify, and deploy it however you want. Exclusive ownership rights available as a buyout if you need them.
Project size
$5,000 minimum. Most projects land between $5K and $50K.
How to start
Send me a paragraph about what you're trying to do. If it's a fit, we'll get on a call for 30 minutes and I'll tell you whether I can help or whether you should hire someone else.
