Position

Freelance Senior Technical Consultant with 20+ years of experience in complex software systems, integrations, and platform-based environments. I work at the intersection of technical execution, process optimization, and delivery support.


In addition to hands-on work, I provide technical leadership and team coordination ? structuring initiatives, clarifying priorities, and supporting stable delivery without unnecessary bureaucracy. I combine clarity, empathy, and pragmatic decision-making while keeping business objectives in focus.


I?m interested in remote B2B projects where I can contribute hands-on and help align technical execution, operational processes, and business needs.
