An internal HR management platform handling employee data, permissions, and cross-border integrations with partner systems. As a Software Engineer, I designed and published internal APIs, enhanced permission controls and data validation for secure API reuse, and generated YAML-based documentation integrated with Scalar UI.

A customer loyalty CRM platform that helps businesses manage contacts, run campaigns, and build landing pages through a no-code website builder. As a Front-end Engineer, I migrated and enhanced features from the legacy system, implemented a media uploader that reduced duplicated file uploads by 30%, and resolved bugs across contact filters, smartlists, and custom contact lists. A key contribution was leveraging GrapeJS to introduce drag-and-drop functionality similar to Canva, reducing website creation time by up to 50% compared to the previous version.
