About
A bit about me
Engineer by training, developer by passion.
I'm a versatile IT professional with a background spanning mechanical engineering, embedded systems, mobile development, and enterprise software. Currently at Celeritas-8 GmbH in Leipzig as an IT Specialist and Odoo-Certified developer.
My daily work involves custom Odoo ERP modules, banking API integrations (Revolut, FinAPI, Tink), web scraping pipelines, and AI-powered automation. I also manage server infrastructure — Docker, VPS, DNS, the full stack.
In parallel, I'm pursuing a Master's in Advanced Manufacturing at TU Chemnitz — bridging traditional engineering with modern software.
