Luby Tecnologia SA

Luby is a Brazilian software development firm founded over 23 years ago by Alon Lubieniecki, Rodrigo Gardin, Jancarlo Romero, and Tiago Carvalho. The company operates 220+ engineers and product specialists and has delivered 1,350+ projects to 540+ clients globally, with particular depth in the U.S. market. Its core thesis is straightforward: complex software gets built at the intersection of engineering discipline, product clarity, and reliable execution. Luby positions itself as an extension of client teams rather than a vendor, co-creating solutions and sharing accountability for outcomes.

The firm's AI-first engineering model claims engineers trained to use AI tools across the software development lifecycle can ship 2-3x faster while maintaining code quality. Every delivery centers on this principle: ship working software that handles production traffic, serves real users, and evolves without disruption.

Services and capabilities

Luby organizes its work into distinct engagement models, each tied to a specific business problem.

MVP Development accelerates from idea to working prototype in roughly one month through a five-step process: discover the problem and success criteria, design product scope and architecture, build production code with AI-assisted development, validate with users, and deliver a production-ready POC or MVP. The company frames this as "Squad as a Service."

Dedicated Team addresses legacy modernization without downtime. Luby squads embed directly into client stacks and codebases, assessing technical debt, designing phased migrations, and refactoring systems layer by layer—frontend, backend, APIs, legacy languages, cloud infrastructure. The methodology spans five phases: assess, integrate engineering squads, augment with AI practices in code review and QA, optimize performance and observability, and scale CI/CD pipelines for sustainable delivery. The firm claims 2x faster delivery cycles, <40% reduced technical debt, 10x improved scalability, and zero downtime.

Staff Augmentation provides pre-vetted, U.S.-timezone engineers deployed in 7 days. Every profile includes technical vetting, compliance checks, and background screening. A dedicated Customer Success Engineer monitors fit and performance.

Beyond these engagement models, Luby delivers custom software development, AI and machine learning solutions, data analytics and business intelligence, cloud services and application modernization, quality assurance and testing, UI/UX design, and product discovery and strategy.

Technology specifics: backend work spans .NET, Java, Node.js, Python. Frontend and mobile use Angular, React, Next.js, TypeScript. APIs are REST and GraphQL. Cloud platforms include AWS, Azure, Google Cloud. Data layers use SQL Server, PostgreSQL, and no-relational databases. DevOps includes Docker, Kubernetes, and CI/CD pipelines. AI work leverages Python, OpenAI, TensorFlow. Testing frameworks are Playwright, Cypress, Selenium. Data tools are Snowflake, Power BI, Tableau.

Notable work

Luby's deepest vertical is financial services. The firm has enabled $41B+ in transaction volume across banking, fintech, payments, and lending engagements.

One named case study is Caliber, a U.S. lending company in a regulated credit market. Caliber's 20-year-old legacy infrastructure could no longer support growth, automation, or security requirements. Rather than a risky rewrite, Luby designed a phased, zero-downtime modernization plan. The firm assessed existing architecture, designed the migration, moved critical services to a multi-tenant microservices architecture, and reduced operational risk while improving scalability. The result was a platform that continued to operate without disruption.

Client testimonials are named. Witoldo Hendrich Junior (CLO, Online IPS) credited Luby for developing their banking integration for loans and buy-now-pay-later transactions. Rafael Rjeille Cordeiro (CEO, Yangflow) praised their understanding of vision and translation into functional product. Jason Meltzer (CTO & Co-Founder, Papaya) noted the team's professionalism, responsiveness, and flexibility. Wilson Baraban Filho (CTO, Inter&Co) said he felt confident performing challenging tasks with Luby as partner. Matthew March (CIO, Sunwest Bank) called them true strategic partners who understand the business.

How they work

Luby engages clients through three primary models: MVP development (fixed-duration, idea-to-MVP), dedicated team (long-term platform modernization), and staff augmentation (specific skill or capacity additions). Each model pairs a defined process with embedded engineers who report to client teams, not separately to Luby.

The firm operates with delivery centers in Brazil and serves U.S. and global clients. Engineers are U.S.-timezone compatible and English-fluent. No timeline or pricing is specified in the source material.
