    Co-Founder @ Lengreo

      Java has been one of the cornerstones of enterprise software for decades, and it continues to hold strong relevance in the UK market. Businesses across finance, healthcare, retail, and technology rely on it to build secure, scalable, and future-proof applications. Its cross-platform flexibility allows teams to support both small-scale systems and complex digital ecosystems.

      Below is a list of UK-based companies offering Java expertise, each with its own focus and delivery model.

      1. Lengreo

      1. Lengreo

      LENGREO works with businesses that need more than just code written. In our approach to Java application development, we try to look at the bigger picture: how the app fits into existing processes, how it will grow over time, and how it can be maintained without unnecessary complexity. For us, writing Java applications is less about quick fixes and more about building solutions that can stand up to real-world use.

      Collaboration is a big part of the way we operate. Instead of sticking to a single model, we adjust our process depending on the client’s needs. Some projects call for close integration with in-house teams, while others work better if we take full responsibility from start to finish. Either way, we aim to keep communication open and make sure the development process is transparent.

       

      Key Highlights:

      • Experience working with different industries in the UK and abroad
      • Flexible approach to collaboration with client teams
      • Focus on long-term usability and scalability of applications

        6B focuses on building and maintaining Java applications for organisations that require resilience, compliance, and long-term scalability. Their approach starts with a planning phase where technical requirements and business goals are mapped out before development begins. The team uses frameworks like Spring Boot, Hibernate, and Jakarta EE, and they integrate with databases, third-party APIs, and identity providers. This makes their systems suitable for industries that need secure, high-volume processing and continuous uptime.

        They adopt modern engineering practices such as modular code structure, automated testing, continuous integration, and performance profiling. Projects can involve new applications, extensions to existing systems, or migrations of legacy platforms to modern architectures. Cloud deployment is also a key part of their work, with support for AWS, Azure, and Google Cloud. Beyond delivery, 6B provides monitoring, optimisation, and feature enhancements, ensuring Java systems evolve with business demands.
