Mikhail Smazhevsky developed and enhanced core APIs and backend workflows for the genestack/openapi and genestack/sdk repositories, focusing on data modeling, analytics, and workflow automation. He implemented endpoints for cell data import, metadata retrieval, and differential gene expression analytics, applying technologies such as Kotlin, Python, and OpenAPI Specification. His work included robust error handling, schema design, and build automation using Gradle, ensuring reliable integration and consistent data validation. By aligning documentation and API behavior across repositories, Mikhail improved onboarding, reduced manual effort, and enabled scalable, permissioned data workflows, demonstrating depth in backend development and technical writing throughout the project.
Month: 2025-12 — Two repositories updated with key features and workflow improvements focused on data import/curation and curator publishing workflows. Delivered Documentation Improvements for Data Import and Curation Workflow in genestack/user-docs and Curator Draft Publication API Enhancement in genestack/openapi. Major workflow fixes include renaming references from staging to draft to reflect unpublished metadata state and updating endpoints to publish from drafts, aligning behavior across both repos. This reduces onboarding friction, improves publish accuracy, and speeds up content publication. Commit context references ODM-12419 and related UX/documentation changes.

November 2025: Completed a major enhancement cycle for the Differential Gene Expression Analytics API in genestack/openapi. Key features include API pagination, role-based access control, corrected and expanded documentation, and schema/type updates to properly handle NaN/Inf values. Added new statistical tests and analytics endpoints to broaden capabilities and adoption. Major bug fixes (ODM-12847) stabilized end-to-end flows, resolved parameter description duplication, and improved test coverage. Python SDK improvements include naming optimizations (shorter identifiers), test data generation, and better parameter handling. Overall impact: more robust, scalable analytics with easier integration, improved end-user experience, and a solid foundation for future metrics and endpoints. Technologies/skills: API design (pagination, RBAC), data handling for NaN/Inf, statistical testing (Mann–Whitney U), Python SDK development, test automation, and comprehensive documentation.

October 2025 — Genestack OpenAPI: Delivered a new API endpoint to link cell expression groups to cell metadata groups, enabling explicit, auditable associations between expression data and metadata. The feature includes defined parameters, responses, and security requirements, with standard HTTP status semantics for success (200), partial success (207), and errors. The work aligns with ODM-12808 and lays groundwork for improved metadata governance and downstream analytics.

In July 2025, delivered a focused enhancement to the Cell Data API in genestack/openapi by implementing endpoints for importing and retrieving cell data, with role-based access controls for curators and general users. The work enables end-to-end cell data workflows and improves data governance and accessibility.

March 2025: Delivered a targeted reliability improvement for the Delete Study or Template Script in genestack/sdk. The changes enhance exception handling to align with server responses, remove non-essential copyright notices, and enforce a non-zero exit status on error, significantly improving automation resilience, error visibility, and downstream CI/CD feedback. This work reduces silent failures and clarifies failure modes for operators and downstream consumers.

Concise monthly summary for 2025-02: Focused on stability and consistency of the Genestack OpenAPI integration. Implemented a robust accession naming fallback to ensure consistent generation of 'genestackaccession' across all contexts (R and Postman) and across multiple OpenAPI generator configurations in build.gradle.kts. The change fixes the incorrect generation of 'genestack_accession' and is tracked under ODM-12402. Impacted business value through more reliable API client generation and reduced downstream issues in multi-context environments.
