App Modernization
I take old systems — COBOL, AS400, legacy ERP, whatever you've got — and rebuild them on modern tech that your team can actually maintain and extend. No rip-and-replace chaos. A structured, phased migration that keeps your business running throughout.
Talk to me about your systemWhat this actually involves
App modernization is a broad term. Here's what I specifically do.
COBOL & AS400 → React / Node / Python
I've worked with mainframe and midrange systems that have been running the same code for 20-30 years. I know how to read it, understand it, and rebuild it without losing decades of business logic.
Phased Migration — No Big Bang Rewrites
Big bang rewrites fail. I work in phases: start with the most painful parts, prove the approach, then move the rest. Your business keeps running the whole time.
AWS & Azure Deployment
Once modernized, your app lives in the cloud — containerized, scalable, with proper CI/CD pipelines and infrastructure as code. No more "it works on my machine."
Data Migration Included
The code is only half the problem. I handle the data migration too — schema transformation, validation, and rollback plans. No surprises when you go live.
What you get at the end
- Modern codebase your team can actually maintain
- Cloud-hosted on AWS or Azure — your choice
- CI/CD pipeline from day one
- Infrastructure as code (Terraform or CloudFormation)
- Complete documentation of the new system
- A 30-day post-launch support window
Not right for everyone
I'd rather tell you upfront than waste both our time:
- Systems that are already running well on modern tech
- Projects with no tolerance for a phased approach
- Timelines under 8 weeks for anything substantial
Not sure if your situation fits? Just describe your system to me and I'll give you a straight answer.
Tell me about your legacy system
Share what you're working with — platform, age, scale, pain points. I'll tell you honestly what's possible and how long it would take.
