Featured Work

ORAXAI

Quality Management System

A quality management platform for regulated workflows, covering documents, deviations, CAPAs, and training.

As the sole engineer, I took it from requirements analysis with QA to the domain model, API, and UI, including a three-level permission model.

LINGA BackOffice

The back office of an enterprise restaurant platform, used for daily restaurant operations and administration.

I migrated its core modules from AngularJS to modern Angular with predictable RxJS/NgRx state, improving performance and making high-traffic screens easier to extend with lower regression risk.

A bilingual reading tracker for logging books, saving quotes, and exploring reading stats, with no sign-up needed to start.

Mercedes-Benz B2B Connect

Mercedes-Benz's global B2B portal for partners, live in 19+ markets.
