Project details
Legacy systems don't fail dramatically. They quietly become impossible to maintain, staff, and extend.
Whether you need to understand what your existing code actually does, or convert it into a modern language and framework, I can help.I've worked with COBOL systems professionally for years, including active modernization work with enterprise clients. I use proprietary AI-assisted tooling developed specifically for this problem (not generic AI code generation) combined with hands-on expert review of every output.
The result is converted code you can actually trust and maintain.This service covers COBOL and Fortran conversion to Python, Java, or PHP, including copybook parsing, data structure translation, database integration mapping, and full documentation of converted logic.
This is not a commodity service. If you have a large or complex system, contact me before purchasing so we can scope it correctly.

Fix PowerShell-to-Linux Remote Execution Script
Aaron was very quick to resolve our non-trivial task to make ML training pipeline interoperable between windows and linux. Thank you!

Back-End and Middleware-Focused Web Development Consultation
He did exactly what I asked, and I didn't have to spend a lot of time managing him to get it done. He worked on our flask framework and solved a particularly nasty configuration problem in a timely manner.

Job Success
Florence, United States - 7:48 am local time
On the development side, I use proprietary AI-assisted tooling I've built myself to deliver work faster and with better consistency than a standard development workflow. Clients get the benefit of that without needing to understand what's under the hood.
My background spans 28 years across Java, Python, PHP, Perl, C/C++, and modern AI/LLM integration. I've built REST services for IVR systems, modernized legacy COBOL applications using AI tooling, worked on encryption and certificate management in Java environments, and handled data migration between contact center systems and reporting platforms.
I work well on:
- AI agent and voice assistant development
- Local LLM system architecture
- WordPress plugin development and optimization
- Full-stack web application development
- Legacy modernization (COBOL, older Java systems)
- REST API design and integration
If you're an agency or development team looking to integrate AI-assisted development tooling into your workflow, that's a conversation I'm open to as well.
Steps for completing your project
After purchasing the project, send requirements so Aaron can start the project.
Delivery time starts when Aaron receives requirements from you.
Aaron works on your project following the steps below.
Revisions may occur after the delivery date.
Analyze Source Code
Your code is analyzed to capture business logic, data structures, and dependencies in enough detail to produce an accurate conversion. You'll receive a summary of findings before conversion begins.
Convert Source Code
Using proprietary AI-assisted tooling combined with expert review, your code is converted to the target language and framework. Every output is reviewed by a human before delivery. This is not an automated pipeline with no oversight.
