AI-Powered · Any Legacy · Zero Downtime
Legacy to Modern.
Without the Risk.
AI uncovers how your system really works. We modernize it module by module, with old and new running side by side, so your business never stops.

From Archaeology to Autonomy
How It Works
Big-bang rewrites try to jump from one peak to the next. We build the path instead, one safe step at a time.
Phase 01
AI Code Archaeology
Before deciding anything, we learn how your system actually works today.
Docs go stale and people move on; the code is the one source that never lies.
What we analyze
- Source code and databases
- Infrastructure and deployments
- Documentation and wikis
- Jira, Azure DevOps and other project tools
- Integrations and third-party services
- Interviews with the people who run it
What you get
- A map of every module, service and dependency
- A catalog of business rules, including the undocumented ones
- A risk and tech-debt register
- One knowledge base of how your business runs, which becomes the shared context for our AI agents, our engineers and your team
Phase 02
Architecture Design
With the full picture, we design the modernization that fits your system, your team and your budget.
Sometimes that's microservices and serverless. Sometimes it's a modular monolith and a new frontend.
What we decide
- What to keep, what to wrap, what to rebuild
- Runtime, cloud and infrastructure targets
- An architecture sized to your real scale
- Where AI adds value, in your product, your code and your operation
- The migration order, by business value and risk
What you get
- Target architecture
- A roadmap with milestones and checkpoints
- Effort and risk per module
Phase 03
Surgical Migration
We move one module at a time. Old and new run in parallel, traffic shifts gradually, and every step can be rolled back.
Each new module is built for what comes next, so your business keeps growing on the new system.
What we do
- Strangler-style migration, one module at a time
- Parallel runs with automated parity checks
- Gradual traffic shift with rollback at every step
- CI/CD, observability and infrastructure as code from day one
What you get
- Modules in production early and continuously
- A system ready to keep evolving after the migration
Phase 04
Validation & Handoff
Your team knows your business better than anyone.
While we build, we learn from them and they learn the new system: we train your team for the new stack, and shape the stack around your team.
What we do
- Validation against legacy behavior (parity, performance, security)
- Hands-on training as each module ships
- Runbooks, documentation and the knowledge base, handed over
WHAT SETS OUR METHOD APART
Three Ways to Modernize. One Keeps You Running.
Most modernizations stall for one of two reasons: they change everything at once, or they translate the code and change nothing that matters.
| Big-bang rewrite | AI on autopilot | White Prompt | |
|---|---|---|---|
| Starting point | Assumptions and stale docs | The code, line by line | AI archaeology plus your team's knowledge |
| What changes | Everything, at once | The language, not the design | The right things, in the right order |
| Your operation | A freeze and a risky cutover | One big cutover | Old and new, side by side |
| First results | When the rewrite ends, if it ends | After full conversion and testing | With the first migrated module |
| Business knowledge | Leaves with the people | Buried in generated code | One knowledge base you own |
| Your team | Left behind | Inherits code nobody designed | Trained, and part of the process |
| After go-live | Dependent on the vendor | The old structure in a new language | Autonomy, with optional continuity |

Questions
Frequently Asked Questions
Ask us anything about our services, process, and rates
No. Old and new systems run in parallel, traffic moves module by module, and every step can be rolled back.
