I’m Piotr Cierkosz, an Odoo developer since 2017 based in Ireland. I’ve published 260+ apps and specialize in practical, production-ready work: models and fields, XML views, QWeb (PDF) reports, small OWL/JS extensions, and REST/JSON-RPC integrations. My teaching style is clear and supportive: short lessons, step-by-step screenflows, copy-paste code, and checklists so beginners can succeed quickly. I focus on helping learners move from a fresh install (Windows/macOS with Docker) to a working module—covering permissions (ACL/Record Rules), view inheritance, PDFs, frontend tweaks, debugging, and smooth local deployment. I create courses in Polish and English and care about making complex topics simple, useful, and fun. If you want real Odoo skills you can apply immediately, you’re in the right place.
