About me
Bilingual PL‑EN specialist with 15+ years of experience in IT, R&D and digital production.
I work fluently in English and have long‑term experience using AI tools for writing, research, documentation and workflow optimization. I create, edit and verify technical documentation, specifications and research materials, and I have authored successful multi‑million‑euro R&D grant applications.
Strong in writing, proofreading, translations (PL‑EN / EN‑PL), data work, structuring information and delivering clear, precise content under time pressure. Supported virtual assistance, customer communication, market research and simple project coordination as part of daily responsibilities.
I’m open to both quick freelance work for extra income and for the chance to build longer‑term collaborations with returning clients.
I focus on clear communication, reliability and consistent quality, so clients who work with me usually come back because they know they can count on solid, timely
