About this gig
Is your business stuck on an outdated system too risky to touch?
I'm a Senior Software Engineer with 15+ years modernizing critical systems
for public-sector and financial institutions. I specialize in migrating
legacy platforms (like OpenEdge Progress) into modern, scalable .NET C# and
Node.js architecture without disrupting your daily operations.
What I bring:
- 15+ years in system architecture and legacy modernization
- Deep expertise in .NET, C#, Node.js, Angular, and SQL databases
- Experience building payroll, HR, and enterprise systems from scratch
- Track record with high-availability systems in demanding sectors
- Clear communication you'll always know what's happening and why
Whether you need a full audit, a migration roadmap, or hands-on execution
of a legacy rewrite, I bring the same rigor I've applied to government and
financial systems for over a decade.
Message me with details about your current stack, and I'll reply with a
clear plan.

I help companies rescue and modernize legacy systems (like OpenEdge Progress) into scalable .NET C#, Node.js & Angular architecture — without disrupting operations. With 15+ years leading critical systems for public-sector and financial institutions, I specialize in safe legacy migrations, multi-tier architecture, REST/SOAP integrations, and building payroll/HR platforms from scratch. Stuck on an old system too risky to touch? Let's plan and execute the migration with zero surprises.
FAQ
Do I need to share my entire codebase with you?
No. For the Basic package, a partial code sample or architecture diagram is enough for a solid audit. Full access is only needed if we move to migration work.
Will migrating my legacy system cause downtime?
My approach is designed to minimize disruption — I typically plan phased migrations so your current system keeps running while the new one is built and tested in parallel.
I don't have technical knowledge — can you explain things simply?
Yes. I have years of experience training engineers and explaining complex systems to non-technical stakeholders. You'll get clear, jargon-free updates throughout.
What if my legacy system uses a technology you haven't listed?
Message me with details before ordering. I've worked with OpenEdge Progress, ColdFusion, and other older stacks — most legacy platforms share common migration patterns.
