Modernize your legacy without putting operations at risk.
When nobody knows exactly what the system does, every change is a risk and AI has nothing to work from. Before migrating, we rebuild the business rules built up over years of code and deliver the map of integrations, risks, and the migration plan, with timeline and cost. You decide before anything changes.
How we work
Projects run late when hard decisions wait for the code. For 24 years we have made them first, with the discipline production systems demand.
Instead of slipping deadlines and compounding technical debt: predictable delivery, modernization without taking the business offline, a team that is productive within 7 days and architecture that scales from day one.

AI Legacy ModernizationWhy Luby
Your CTO asks whether the foundation will hold. Your CFO asks what it costs and when to stop. Your CEO asks whether the strategy can move without waiting on a hire. Here's what Luby delivers to each of them.
Less technical risk on the decisions your team can't afford to get wrong.
Pre-vetted engineers and product specialists join your team within days. You own the roadmap; we sustain the squad and the delivery pace, with 220+ professionals across 40+ technologies.
The system running today carries your revenue and can't stop. We modernize it and integrate with what already runs, planning the migration around your operation and mapping business rules before a single line of code.
Security is designed in from the start, governance and observability ship with the work, and we have had zero critical incidents across our operation. We are ISO 27001 and 27701 certified.
Predictable cost, with the exit defined before you invest.
You know what you'll invest before the larger commitment. A discovery of up to 4 weeks settles requirements, cost, and schedule. Under a fixed-scope engagement, the price holds as long as the scope does, with delivery against milestones on a timeline of up to 6 months.
Hiring domestically carries benefits and overhead on top of salary and takes 30 to 90 days to close. We staff within 7 days, bill for hours worked, and scale capacity up or down as the roadmap changes.
95% of AI pilots never leave the experiment stage. That's why, on AI work, we define the P&L metric and the kill criteria before anything is built, so continuing depends on results.
A partner accountable for the outcome, not one more vendor.
1,350+ projects delivered for automakers, Big Four consultancies, industrial automation multinationals, and global data providers. Rated 4.8 out of 5.0 on Clutch in verified client reviews.
When a vendor ships and walks away, the production problem stays with you. We come in as a strategic partner embedded in your team and answer for the outcome, not just for hours delivered.
Your strategy shouldn't sit idle waiting for a requisition to close. Our teams work in US-overlapping time zones, so reviews, standups, and escalations happen inside your business day.

How we work
Actually senior, not juniors with a title.
Engineers with real experience on complex systems make the calls that keep your project out of rework. Every one of them is selected for technical depth, autonomy, and ownership of the result.
The spec is settled before the first commit.
A good project starts before the first line of code. We write precise specs, model the data, and define clear contracts, which cuts rework and speeds up delivery.
Nothing ships without clearing the pipeline.
Nothing reaches your infrastructure without a security review, automated tests, and a compliance check. Our architects review every delivery.
Modular from day one.
Your system has to keep up with the business, not just look good in a demo. So we build modular, observable systems on microservices, cloud-native infrastructure, and well-defined APIs.
Capabilities
Automation, predictive analytics, and autonomous agents applied where they move business results.
