Viktor Schumann

I'm a NetSuite specialist with over 10 years of hands-on experience designing, developing, and optimising complex client- and serverside customisations, integrations, and approval workflows. I was a key contributor to one of the largest NetSuite implementations worldwide, supporting 45 subsidiaries across multiple languages and currencies over a seven-year period. My skillset combines deep technical expertise with more than 20 years of broad ERP and business process knowledge across retail, manufacturing, and other industries.

I have proven ability to translate complex client requirements into clean, maintainable, and scalable solutions. Earlier in my career, I spent several years managing projects and teams delivering ERP and CRM/SFA implementations in Hungary. This experience gave me a strong foundation in both technical delivery and stakeholder management.

I have been a British citizen since 2024.
