Be sure to contact Akveo https://www.akveo.com/ They have a very cool open source product NgX Admin. With it you can build your product faster. Choose one of the six visual themes (cosmic, light, dark, corporate, material light, and material dark) or just add a few custom variables. Packed with a huge number of handcrafted UI components, charts, maps, editors, and tables, ngx-admin is free and MIT-licensed. We can say that this is a project in the portfolio, but thanks to such a project you understand what a team in this company is capable of. That's why I recommend them to you.
