Legacy Modernization We can read your 15-year-old Java because we built that era.

We modernize and AI-enable the enterprise Java and .NET systems that still run your business — using AI-assisted analysis and migration to cut the time, cost, and risk of a traditional rewrite.

01The problem

The system still runs the business. The people who built it are gone.

Systems built 2005–2015 (Spring, Hibernate, Struts, EJB, monolith .NET) still run the business, but the engineers who built them are gone.

Documentation is stale. Every change is risky. AI initiatives stall because they can't integrate with the legacy core. Full rewrites are quoted in years and millions.

02What we do

Modernize in steps, not in one risky leap.

AI-Assisted Codebase Analysis

We generate current-state architecture docs from the code itself — dependency maps, risk registers, and documentation your team lost when developers left.

Risk-Ranked Modernization Roadmap

Prioritized, costed, sequenced plan with go/no-go honesty at every phase — not a big-bang rewrite quote.

Incremental Migration

Strangler-fig pattern: APIs around the monolith, then service extraction. Production stays running throughout.

AI Enablement + Cloud Migration

Expose legacy knowledge to RAG and agents, then migrate modernized workloads to the cloud when ready.

03The differentiator

Built that era. Fluent in today's tools.

Modernizing a legacy system takes engineers who understand how it was built. We've shipped enterprise Java since 2008, including subcontracted work for Fortune 500 companies — and now we combine that fluency with AI-assisted migration tooling. AI tooling takes over much of the manual analysis and conversion work, so senior engineers spend their time on design decisions — and you get a faster, lower-risk migration.

06FAQ

Questions we hear most

No. We use incremental strangler-fig migration — APIs around the monolith, then service extraction. Many systems need targeted modernization, not full replacement.

No. Production keeps running throughout. Cutovers are phased with rollback plans at every step.

It's the most common situation we see. The AI-assisted analysis phase rebuilds the missing knowledge from the codebase itself — generated docs, dependency maps, and risk registers.

Java/Spring/Hibernate/Struts, .NET Framework to .NET, classic three-tier and monolith architectures, and their databases.

Modernize without the big-bang rewrite.
