Regain Control of Your Legacy Systems

 

Secure, AI-assisted code analysis and modernization planning — without risking your data.

The Challenge

 Legacy Systems Holding You Back 

Knowledge Blindness 

PROBLEM

Minimal or outdated documentation causing blind spots and operational risk

IMPACT

Your team can't confidently make modernization decisions—time and cost estimates are unreliable.

Developer Friction

PROBLEM

Undocumented code, lost developer knowledge, and fragmented specifications

IMPACT

Onboarding takes months, not weeks. Maintenance becomes a bottleneck.

 

Architecture Risk

PROBLEM

Outdated requirements obscure behavior, dependencies, and architecture fit

 

IMPACT

Refactor vs. extend vs. rewrite decisions lack clarity — leading to costly missteps. 

 

Our Approach

AI + Human Expertise

NexDevTech combines AI-powered analysis with senior expert validation to transform your legacy systems from operational liability into strategic assets. We deliver security-first, actionable intelligence and keep your data completely isolated.

Your Data Stays Yours

Enterprise-grade security without compromise. All processing runs in isolated, secure environments — no external model training, no unauthorized sharing.

Data Isolation

● Processing runs in isolated, secure silos
● Your code never trains public models
● Option for private, self-hosted infrastructure

Flexible Deployment 

BUSINESS: API-based (faster, cost-efficient, security managed by provider)
PRIVATE: Self-hosted (maximum control, dedicated infrastructure)

Compliance-Ready 

● CCPA, GDPR, HIPAA, PCI-DSS, export controls
● Audit-friendly workflows and documentation
● Governance materials included

Transparent Oversight

● Human expert review of all AI outputs
● Client approval gates at each stage
● Full visibility into methodology and findings
