Testimonials
I had the pleasure of working with Amina during a NetSuite implementation project while I was heading the finance team of a software scale-up.
Amina knows NetSuite inside out, has deep accounting knowledge, and always approached problems from the user perspective instead of just processing clearly defined requirements.
Alongside developing customized solutions for long-grown workflows, FX accounting, and intercompany billing, she also rolled up her sleeves when necessary to support us in recording large amounts of booking transactions during the migration process. Her “whatever the customer needs” approach impressed and surprised me many times, especially when she brought a solution in the morning to a problem we approached her with the evening before.
Amina has the skill, commitment, and reliability that you want on your project, and I highly recommend her.
Arne Nowak
We worked with  Amina during our NetSuite implementation, where she supported us in setting up and stabilising our daily accounting operations. She quickly understood our business model and translated German accounting and reporting requirements into a clean and workable system setup.
She combines strong NetSuite expertise with a solid understanding of German GAAP and practical finance processes. Her responses were always fast, precise, and solution-oriented. She was not only executing tasks but also acted as a true sparring partner — helping us structure ideas, challenge assumptions, and turn concepts into workable solutions.
Even today, she remains our go-to expert when issues require immediate attention or pragmatic problem-solving. Her proactive mindset and reliability were instrumental in establishing robust accounting processes after go-live.
I would highly recommend her to any company looking for hands-on, pragmatic NetSuite and finance expertise.
