We cooperated with Sigli for the software modernization project. Their team helped us breathe in a new life into a legacy software system for a logistics company. The platform was built 12 years ago and since that time the architecture and the used technologies have become obsolete. Sigli’s developers migrated the solution to the Azure cloud and upgraded its architecture so that it could be easily integrated with other software systems used by the company. We liked the way the Sigli team solved the set tasks and organized the working process.

Sigli’s contribution was pivotal in the success of the web portal project. Their .NET back-end developer seamlessly integrated with our team, and the project not only went smoothly but was also completed on time—something the client wasn’t used to experiencing. The quality of their work impressed the client so much that they repeatedly hired us afterward to add more functionalities to the portal. Sigli demonstrated expertise, reliability, and a commitment to excellence throughout the engagement.

We hired Sigli to develop an AI chatbot solution to help us automate the processing of common inquiries from our customers (including retrieving order statuses), reduce response time, and enhance the customer experience overall. That’s why we needed to find a team with outstanding expertise in AI development.

I had a brilliant experience working with Sigil. We've hired them as an expansion for our team to take a part of the software they have been working on. And it worked out perfectly. They did a right job, bringing confidence and results to the table. We had no issues, as they were very proactive and all the time in touch with our team, which made us feel they are just a part of our office. Besides that, they weer giving NO false promises, so we all the time had a clarity for the future steps planning. Very decent experience.
