Working with Andersen, we have the possibility to access a pool of skilled developers on-demand, as well as the ability to scale resources up or down as needed. They have a wide range of developers with different skill sets and experience levels to meet the needs of various projects. Communication with the account managers is good and the issues are addressed quickly

We found them through a mutual connection. Their prompt communications, structured process, and quality of talent all contributed to our decision to source talent from them. We use their services to design, document, develop, and test core components of our code review tool. This includes producing diagrams and mockups in Figma. Documenting components of our tool in Confluence and assisting with story tickets in Jira. Development in React and JavaScript for the front-end and back-end respectively. Finally, running tests and automating test-rails to ensure the product is functioning as expected. The product is still being developed with assistance from all of these business units. Thanks to their talent, we have significantly sped up our time to market estimate. We are constantly able to deliver new features sooner than expected thanks in large part to the structure their talent provides to our business processes.

We hired them to do 2 things for us: 1) We had a fledgling technology function that had recently experienced turnover of staff at the leadership level and was running without a structure - we brought in a project manager to implement agile/scrum processes into the team, improve interfaces into the business and ensure our two upcoming product releases were released on time. We now have a solid structure and cadence in place and both products were releases on schedule. 2) We are in the process of building a future platform for the business and had a wealth of business analysis work that needed to be done - understanding and documenting existing processes and internal systems, designing the future state with a platform, capturing platform requirements and designing prototypes for the first few releases. All were done in record time, to a quality that far exceeded expectations.

We arehave been working with a team of 15 engineers from Andersen at the development of a Banking Orchestration Platform for 8 months now. The platform is build on microservices in Mircrosoft's Azure Cloud. We are very happy we have contracted with Andersen for this huge software project. We collaborate with the team of high professionals in a very productive and constructive atmosphere although the communication is only via video conferences, chat and e-mail. We would choose Andersen again at any time and can recommend the company for the execution of large software projects.

We work with Andersen in two direcrions. As part of the first, they help us with outstaffing employees. Developers come experienced and diligent. We are pleased with the quality of their code. In the second direction, we work on the outsourcing model. We have given away building an automated infrastructure (IaC) and ci/cd processes. The team is doing great, they always give us advices on different questions. The work of the team is completely transparent to us thanks to constant reports and presentation from PM.

Anna has been our point of contact from the start and has been great, gave us the time and space we needed to make a decision but was there when we needed her. Yjinia joined us as a BA and has done an outstanding job of picking up several projects, she is thorough and pays attention to detail. Yjinia has a very calculated approach to analysing problems and is able to produce detailed requirements very quickly, her work is extremely organised and has helped our team even in the short time se has been with us. Would definitely recommend Andersen for anything requirements and software related.
