The "Zero Debt" Guarantee
Stop renting your infrastructure. Escape vendor lock-in and own 100% of your technology stack.
Zero-Downtime Migration
Through advanced dual-write ETL pipelines and the Strangler Fig pattern, your legacy system runs in parallel with the modern cloud-native system. Departments transition sequentially without a single dropped user session or missing data byte.
100% Code Ownership
No SaaS traps. No recurring seat licenses. You own the fully modernized source code, documentation, and IP.
Zero Vendor Lock-in
Built on standard, open-source cloud technologies (React, Node.js, Next.js, .NET 8). Any competent team can maintain it.
Eliminate Security Vulnerabilities
Decades-old legacy systems are a prime target for ransomware and data breaches. By refactoring to modern microservices, we enforce zero-trust security policies, end-to-end encryption, and compliance with modern enterprise data standards from Day 1.

Our Approach
Legacy Modernization: Our Proven Process
01
Discovery & Dependency Mapping
AI scans the monolithic codebase for tight coupling, extracting rules to design bounded contexts.
02
Target Architecture Design
Senior architects design the cloud-native, microservices-based target state.
03
AI-Assisted Code Refactoring
Agentic AI accelerates enterprise software refactoring while human engineers harden every component.
04
Automated ETL Data Migration
Safely transfer legacy data to modern SQL/NoSQL cloud stores with byte-level validation.
05
Parallel Run & UAT
Implementing the Strangler Fig pattern, the new system runs alongside the legacy system for zero-risk cutover.
06
Decommission & Handover
Retire the legacy system completely and transfer 100% of the IP and runbooks to your team.

FAQ

The most effective strategy is a phased approach using AI for application portfolio assessment, followed by agentic software refactoring into a microservices architecture. This mitigates risk and speeds up delivery.
Our AI agents ingest the full monolithic codebase—whether COBOL, VB6, or Delphi—and produce structured documentation and entity-relationship diagrams in days. It then generates 70% of the modern boilerplate code.
We achieve "Legacy Zero" by ensuring the target architecture is fully cloud-native, decoupling monolithic constraints, and transferring 100% IP ownership to you, eliminating vendor and SaaS lock-in permanently.
Yes. We utilize the Strangler Fig pattern and automated dual-run ETL pipelines. This allows departments to transition sequentially to the new microservices architecture with absolutely zero operational downtime.
We handle COBOL, VB6, Classic ASP, Delphi, FoxPro, PowerBuilder, Oracle Forms, legacy Java EE, old .NET Framework applications, and more.
Absolutely. We recommend a module-by-module approach — start with the highest-pain system, prove the model, then expand. This reduces risk and delivers ROI faster.
