PROFILE

Vladimir

Worked on the phalcon/cphalcon repository to enhance performance and reliability in PHP backend systems by addressing memory management issues within the PHQL parser. Using C and PHP, resolved memory leaks by removing unnecessary reference counting, which stabilized memory usage during repeated query executions and reduced the risk of memory-related incidents in long-running processes. Expanded test coverage by introducing a new test class for the MVC Model Query Builder, focusing on memory usage stability and regression prevention. Demonstrated skills in debugging, database management, and unit testing, delivering targeted improvements that strengthened the reliability and maintainability of the codebase over the month.
