Ahmadova Goychak developed core features for the Digital-Invoice-Processing-System-Atlas repository, focusing on scalable invoice processing and secure user onboarding. Over three months, she established robust database schema management using Liquibase and PostgreSQL, implemented batch-driven invoice status updates with a state machine pattern, and introduced PDF invoice generation. Her work included designing passwordless authentication and organization-based registration approvals, streamlining enterprise onboarding. She applied Java and Spring Boot for backend development, leveraging Mapstruct and Lombok for maintainable code. By addressing data integrity, dependency injection, and local development setup, Ahmadova delivered a maintainable, extensible backend that supports automated invoicing workflows and enterprise requirements.
September 2025 — Digital-Invoice-Processing-System-Atlas (cybernet-internship-2025): delivered a streamlined, passwordless onboarding flow with enterprise-focused registration approvals. Implemented organization-based registration approvals, removed the approved flag from the user entity, and relaxed the password NOT NULL constraint to enable passwordless authentication. Addressed critical registration workflow issues and completed essential schema and service changes to support frictionless onboarding for enterprise customers. This work accelerates sign-ups, reduces password-related support, and strengthens security posture across the platform.
