PROFILE
Jocelyne
Jocelyne Abi Haidar contributed to the JetBrains/Exposed repository by expanding the SQL DSL’s capabilities and improving its reliability. She implemented six subquery comparison operators, enabling direct comparisons against subquery results and supporting more complex query patterns. To ensure robust parameter handling, she added targeted tests for boolean and numeric types, enhancing the reliability of parameter binding and query execution. Jocelyne also stabilized the project’s CI pipeline by resolving SQL Server startup issues in TeamCity using Docker and SQL Server configuration. Her work demonstrated depth in backend development, database testing, and DevOps, resulting in a more expressive and stable Exposed library.

Jan 1, 2025January 2025 – JetBrains/Exposed: Implemented six subquery comparison operators for the Exposed SQL DSL (eqSubQuery, notEqSubQuery, lessSubQuery, lessEqSubQuery, greaterSubQuery, greaterEqSubQuery) to enable direct comparisons against subquery results. Added comprehensive tests for these operators (including eqSubQuery and notEqSubQuery). No major bugs reported this month. This work expands DSL expressiveness, enables more complex query patterns, and improves reliability for customers relying on subquery-driven filtering. Key commits include 82df93fe8aeb35abd84a85593ec23854761b24dd and 1eead4ebdd45ade916aed0191e1506acfb0396a0.

Nov 1, 2024Month: 2024-11 — Focused on strengthening the Exposed SQL library by expanding test coverage for parameter handling. Delivered targeted tests for booleanParam and a comprehensive suite of numeric parameter types (integers, unsigned integers, floats, doubles, decimals), contributing to more robust binding and query execution. This work improves reliability for downstream users and reduces risk of regressions in parameter handling.
