Experienced Developers and Consultants for Complete Deliveries
Lemontree’s development team can help you with overall deliveries of development projects, but also support on a consulting basis in a number of different areas that can be part of an overall delivery. We have solid experience of projects with a high level of complexity and industry-specific requirements. We focus on your specific challenges and analyze, develop, implement and support you throughout the journey.
As we also have test automation and DevOps experts, we can tie the knot and deliver entire projects with all the components needed for a finished delivery.
Lemontree has been delivering quality assured systems for two decades – let us help you too!
We have developed and refined complicated system structures for customers with very advanced requirements, partly from a speed and scalability perspective, partly by working closely with the customer and with their industry-specific niche needs.
We can help you as much as we can before you know what to do. Then we support you through the entire process.
Which system should you use? It is not an obvious question. There are both licensed products for many purposes, but what is perhaps increasingly common today is using open source frameworks. The cost of these is of course lower than a license product, but you pay instead for the implementation. We have put together a small guide for what is important to think about – and how we can assist you.
Your Guide in the Open Source Jungle
Using an open source framework can offer many benefits, such as cost-effectiveness, customisability, and a large user community that can help solve problems. But there are also challenges to consider. What is really difficult in the open source world today? We help you navigate:
- You need to know what suits your organization. Here we can act as a sounding board and provide support and advice in how you should think and act against the background of your already existing product catalog and what you want to achieve in the future.
- An open source framework does not implement itself. Our experts are very used to implementing new frameworks, even in an already complex structure with legacy systems and many microservices.
- Open source frameworks are usually run by a community of developers and there is not always a formal support structure available. This may mean that you do not have access to fast and efficient support if you encounter problems or need help. Using an open source framework may therefore require the developers to have specific knowledge and experience with the framework. This may mean investing time and money in training developers and staff to ensure they have the right skills to work with the framework. Our developers come across new languages and frameworks almost every day and are absolutely phenomenal at adapting to new circumstances and helping you both with startup and support.
- Security: Because open source frameworks are open to the public to use and modify, there is a risk that security flaws can be exploited by malicious users. It can also be difficult to identify and fix security issues due to the open source code and the large number of contributing developers. We have both competence and solutions for security checking code.
- Compatibility issues: when using an open source framework, it is important to ensure that it is compatible with the other technologies and systems used in the organization. If there are compatibility issues, it can lead to bugs and other issues that can affect productivity. We know from experience that the level of complexity often increases rapidly when it comes to compatibility. This is not a dime-a-dozen knowledge. Many are simply unable to see the whole picture. However, our teams have done this in a number of very advanced projects.
- Dependence on the developer community: open source frameworks often depend on an active and engaged developer community to continue to be developed and updated. If the community decreases in size or no longer supports the framework, it can mean that updates or support are no longer available, which can lead to problems for the organization. We can assist you over time with management and maintaining competence.
Advanced system integration is about connecting several different systems in a seamless way to create a uniform, efficient and stable IT infrastructure. This means dealing with more complex integrations where several different systems or technologies need to work together.
Here are some steps that can be included in the process of implementing an advanced system integration:
- Plan the integration: Carrying out an advanced system integration requires careful planning. This includes identifying the various systems that need to be integrated, defining the integration scenario, preparing the data and identifying any security or privacy risks.
- Design the integration: The next step is to create a detailed design for the integration. This includes defining interfaces between systems, determining how data should flow between systems, developing and testing APIs and other integration components, and ensuring that systems work together.
- Implement the integration: Once the integration has been planned and designed, you can start implementing it. This includes integrating third-party tools and components, migrating data, testing and debugging the system, and ensuring everything is working as it should.
- Test and validate: After the integration has been implemented, you need to test and validate the system to ensure that everything works as it should. This includes testing at all levels of the system, including unit testing, integration testing, system testing, and acceptance testing.
- Document and maintain: After the integration has been implemented and tested, you need to document and maintain the system. This includes documenting the integration scenario, maintaining APIs and other integration components, monitoring the system, and troubleshooting any issues that arise.
By following these steps, you can implement advanced system integration and create a uniform, efficient and stable IT infrastructure. However, it is important to bear in mind that it is a demanding process that requires time, resources and technical expertise.
We have been modernising customer solutions for 20 years and have very solid experience with complex system integrations. We evaluate and implement new frameworks all the time and it’s not a dime-a-dozen knowledge. It quickly becomes complex, which we know and can handle. Let us help you!
Digital Integration Hub
We have often used the product Digital Integration Hub (DIH) for integrations. The typical customer for DIH is someone who is sitting on a large old data solution (legacy system) and who has speed and scalability problems. Here it is not necessarily about rewriting or throwing out the systems, but instead about encapsulating them. This means that instead of talking to the mainframe, you talk to the services in DIH, and thus get completely different response times. What happens when you put something “in between” the old system and the new one is that you instead work towards DIH. Instead of spending time on complicated and inefficient management of the old systems, you can focus on business logic and business development.
Over time, we have developed the professional service package Sugar, which can therefore be used by those who want to build a third generation system from scratch. To make it possible and also to limit the time consumption, we offer predetermined techniques, working methods and application management that handle the tough tasks that would otherwise take years to implement ourselves.
SUGAR is thus both a platform with advanced technologies and a method for how you should code. Instead of spending a lot of effort considering tools and then managing them individually and among themselves, which can be both complicated and unwieldy, SUGAR offers a standardized approach that brings peace of mind to your development team. This also enables greater excellence as there is an elaborate system within which everyone works. SUGAR is thus the framework for you who code, while e.g. deploy to Kubernetes is the administrative.
Sugar is a further development of Gigaspace’s products, which lie at the bottom. We have subsequently adapted the product with both advanced technologies and methods. We have e.g. built a workflow engine, an OAUTH and a microservices framework as individual products within the framework of Sugar.
Today, many people confuse development with administration and management of tools. We don’t. We know the difference and we can really develop. Simply put, you can say that the choice of tools is secondary to us. We have extensive experience in developing without using off-the-shelf components or third-party tools. This requires extensive technical competence and experience. We can also further develop already selected frameworks and applications and adapt to your business and toolbox.
We have expertise in various areas, including but not limited to:
Backend: Java, Spring, Springboot, C++, Python, .Net
Frontend: React, iOS, Android, NodeJS, Jenkins
Process Steps for Developing Advanced Applications from Scratch
Here are some steps that can be included in the process of developing an advanced application from scratch:
- Define the requirements: In order to succeed with an advanced development from the ground up, it is important that you have a clear picture of what you want to achieve. This includes defining functional and non-functional requirements, user needs, technical constraints and objectives.
- Design the architecture: The next step is to create a detailed architecture design, including an overall system architecture, database design, user interfaces, APIs, and integration points.
- Implement the system: Once the architecture has been defined, the implementation of the system can begin. This includes creating the codebase, integrating third-party tools and components if necessary, testing the system, and managing any bugs and issues that arise during the process.
- Test and validate: An advanced development process requires extensive testing to ensure that the system works as intended. This includes testing at all levels of the system, including unit testing, integration testing, system testing, and acceptance testing.
- Deploy and maintain: Once the system is tested and validated, it can be implemented and deployed in the production environment. After that, it is important to continue to monitor and maintain the system to ensure that it continues to function properly.
By following these steps, one can develop an advanced application from scratch and achieve a high degree of customisation and control over the system. However, it is important to bear in mind that it is a demanding process that requires time, resources and technical expertise. We help you from grain to loaf.
