PROFILE
Felix Touchte Codjo
Over three months, contributed to the JeffersonLab/coatjava repository by developing and refining backend systems for detector data reconstruction and calibration. Focused on integrating calibration constants infrastructure with CCDB, enhancing time-based event decoding, and improving AHDC data quality through fine timestamp correction and bitwise operations. Extended data structures to support enriched hit and track metrics, normalized data formats for downstream compatibility, and integrated simulation data processing. Applied Java and Python for backend development, leveraging object-oriented programming and low-level techniques to streamline data acquisition, processing, and analysis. Maintained code reliability through targeted bug fixes, code cleanup, and comprehensive unit testing throughout the workflow.
