PROFILE

Danylo Korostil

Worked on the preset-io/superset repository to deliver two core features over two months, focusing on backend and internationalization improvements. Implemented UUID-based resource identifiers across datasets, charts, and dashboards, updating API endpoints and schemas to support stable cross-system references and enhance data integrity. Leveraged Python for backend development, database integration, and schema design, ensuring forward-compatible identity semantics. Additionally, contributed Ukrainian UI localization updates, expanding translation coverage and improving accessibility for Ukrainian-speaking users. Demonstrated skills in i18n, localization workflows, and Git-based version control, while aligning changes with release plans and maintaining clear commit traceability throughout the development process.

Summary for 2025-08: Delivered UUID-based resource identifiers across the preset-io/superset API surfaces (datasets, charts, dashboards). Implemented support in read endpoints and updated schemas and models to accept and return UUIDs, enabling stable cross-system referencing, improved data integrity, and smoother migrations. This work reduces coupling between environments and paves the way for external integrations and more scalable data pipelines.
