Backend
Hire Java engineers built for systems that cannot fail.
Spring Boot, microservices, JVM tuning — our nearshore Java squads ship backends that stay up.
Why it matters
Why Java still wins where uptime matters
Java runs banks, airlines, exchanges, healthcare claim systems, and the largest enterprises on earth. The JVM remains the most mature, observable, and tunable runtime for high-throughput backends. Spring Boot has kept Java productive — but the talent market is aging, and senior Java engineers with modern (Java 21+, virtual threads, GraalVM) experience are scarce.
Where Java earns its keep
Core banking, payments, and trading platforms
Healthcare, insurance, and claims processing systems
High-throughput APIs and event-driven microservices
Modernizing legacy Java EE / Spring 3.x estates
Why outsource
How outsourcing accelerates your Java roadmap
Senior Java is one of the hardest hires in the US market. LATAM has deep Java benches — and Luby has spent 23 years building those teams.
Regulated-industry engineering, by default
Code review, audit trails, observability — the standards Luby learned shipping bank software.
Modern Java fluency
Java 17/21, virtual threads, records, pattern matching — engineers who use the new tools well.
Spring ecosystem mastery
Spring Boot, Cloud, Security, Data — depth across the stack, not just one corner.
Modernization without breaking
Strangler-pattern migrations from monoliths to microservices, with safety nets at every step.
What we ship
What our Java squads deliver
Java in production is a marathon. Our engineers ship code that compounds in value across years, not just sprints.
Spring Boot platforms
Modular monoliths, microservices, event-driven, all proven in prod.
JVM performance tuning
GC tuning, profiling, virtual threads, GraalVM native images.
Legacy modernization
Java EE, Spring 3, monolith decomposition — incremental and reversible.
Hire Java engineers in 48 hours.
From greenfield Spring Boot to multi-year legacy modernization, our Java squads bring the depth your platform needs.
