codeblue

Codeblue is a Polish software development firm focused on custom applications and data migration work, particularly for financial institutions and startups. The company offers three core service lanes: discovery and design (business analysis, architecture, MVPs), experience and development (customer journey mapping, UI, coding), and testing and integration (QA, security validation, system integration). Their portfolio leans heavily toward banking—they've worked with Raiffeisen, BNP Paribas, and a Swiss bank on large-scale data migration projects, including a 5 billion record migration they describe as error-free. They also built the in-app provisioning and verification layer for Google Pay and have designed consumer wellness and education apps.

Services and capabilities

Codeblue packages work into discovery-through-delivery phases. On the discovery side, they conduct business and system analysis, design architectures, and scope MVPs. In development, they map customer journeys, create UI mocks, and handle coding. For quality assurance, they run unit tests, performance tests, and security tests before handoff. They explicitly mention designing ETL and ETLR processes, managing big data migrations, building APIs, and optimizing database structures and indexing for high-volume systems.

Their technical stack spans C/C++, .NET, Kotlin, Swift, Angular, React, and JavaScript. They also list experience with low-code/no-code platforms. Across their case studies, the emphasis is on handling large transactional datasets and payment system integration rather than consumer consumer product development, though they have shipped both an educational tablet app and a wellness platform.

Notable work

Codeblue migrated 5 billion customer records for Raiffeisen and BNP Paribas using a custom parallel ETLR process with zero errors. For BNP Paribas specifically, they built an application managing transaction history for customers, designing the message broker-to-core system pipeline and handling database optimization. They assisted with a second Raiffeisen project during a bank merger, transferring historical data and analyzing key datasets. For a Swiss bank (cshark), they migrated 500 million records and handled database reindexing. They implemented Google Pay's in-app provisioning and verification, including the first card tokenization on the Polish market. On the consumer side, they designed a tablet-oriented educational app with readable text-heavy interfaces and a wellness app offering goal setting, courses, and specialist recommendations.

Clutch reviews average 4.9/5.0. BNP Paribas's IT Project Manager noted the team "transferred millions of records within a few days, creating an efficient solution" and praised their communication and transparency. Raiffeisen's IT Project Manager credited them with migrating historical data during a merger. Google's EMEA Payments Partnerships lead said codeblue would "guide you through the entire implementation from designing the solution to the first tokenization."

How they work

Codeblue leads with detailed analysis: business, functional, process, and system assessment before design. They then validate concepts through prototyping and customer feedback before building. Across their site, they stress simplicity and customer focus—testing with end users to ensure solutions work as expected. They describe their approach as agile. The company positions itself as a partner through the full software development lifecycle, from vision to post-launch. No specific pricing or minimum engagement terms are mentioned.
