FULL STACK DEVELOPMENT Beyond Odoo, I build business applications using React, Next.js, Node.js, NestJS, FastAPI, Python, TypeScript, PostgreSQL, MongoDB, Docker, and AWS.

I then define what should be configured, customized, integrated, migrated, optimized, or rebuilt. My focus is on maintainable development, accurate data, stable integrations, proper testing and clear communication. Whether you need an Odoo implementation, custom module, ERP integration, migration, full stack SaaS platform, customer portal, API development, automation system, or rescue project, send me your current setup and the main challenge affecting your operations.
