Bc. Sebastian Kychatyi

Summary

Python backend and full-stack developer focused on business systems — ERP, e-commerce and SaaS. I own features end to end, from the database schema to the UI and deployment.

I built a warehouse management system in Odoo 18 for an e-commerce company and created e-drivebook, a SaaS for driving schools, from scratch — it is in production and used daily by 3 paying driving schools.

I am a Master’s student in Applied Informatics at Constantine the Philosopher University in Nitra. At Duo Studio I handle backend, integrations and AI automation.
