Platform & Legacy System Modernization
Modernize while staying live.
Companies with real customers, real transactions, and production systems cannot afford risky rewrites or downtime. The Evolution Track™ is Luby's approach to legacy system modernization and platform evolution, designed to keep your systems running while they scale.
As platforms grow, legacy architecture becomes a blocker to speed and innovation.
Legacy systems slowing down every new feature
Technical debt compounding over time
Manual processes limiting automation and efficiency
Fragmented integrations across third-party partners
High risk associated with full system rewrites
This is why incremental, zero-downtime modernization is critical.
We modernize systems at every layer of the stack:
Modernization of web and mobile applications to improve performance, usability, accessibility, and maintainability.
Refactoring monoliths, redesigning APIs, and migrating services to scalable, modular architectures.
Upgrading or refactoring systems built with obsolete or outdated languages and frameworks, reducing risk and long-term maintenance costs.
Migrating and optimizing systems for cloud-native environments with improved scalability, security, and observability.
The Evolution Track™ focuses on application and platform modernization, not disruptive rebuilds. We modernize systems step by step, aligning technology decisions with business priorities — the same approach used with Caliber, a U.S. lending company operating in a highly regulated credit market.
Building a Sustainable Technology Foundation for Growth
Caliber needed to modernize a 20-year-old legacy infrastructure that could no longer support growth, automation, or security requirements.
Instead of a risky rewrite, Caliber partnered with Luby as a strategic modernization and engineering partner.
Assessed the existing architecture and processes
Designed a phased, zero-downtime modernization plan
Migrated critical services to a multi-tenant microservices architecture
Reduced operational risk while improving scalability
The result was a future-ready platform that continues to operate without disruption.
Architecture & Technical Debt Assessment
We conduct a full technical and business assessment to identify bottlenecks, risks, and modernization opportunities.
Engineering Squads Inside Your Stack
Luby engineering squads integrate directly into your existing codebase, tools, and workflows.
AI-Enabled Engineering Acceleration
We apply AI-enabled practices to code review, testing, and QA to improve delivery speed and quality.
Refactoring, Performance & Observability
We refactor critical modules, improve latency, reliability, logging, and system observability.
CI/CD, Governance & Sustainable Delivery
We harden CI/CD pipelines, introduce technical governance, and prepare the platform for long-term growth.
Based on real-world modernization projects like Caliber, companies using the Evolution Track™ achieve:
Faster and more predictable delivery cycles
Reduced technical debt and operational risk
Improved scalability and system reliability
Zero downtime during modernization
A platform ready for continuous innovation
