At ООО «DIY Service», I designed a relational database from scratch with 12 tables normalized to BCNF. I wrote triggers to automatically deduct spare parts from inventory and created a transactional stored procedure with rollback on failure.
For my diploma project, I developed a working MySQL 8.0 database for a computer repair service center, including views for different roles and access for three user roles. I graduated in 2026 with honors in Information Systems and Programming.
