PROFILE

Viktor Pec

Worked across the DUNE/duneopdet, DUNE/dunecore, and DUNE/duneprototypes repositories to deliver robust detector simulation and data processing features. Developed and maintained C++ modules for geometry definition, signal processing, and calibration, leveraging CMake for build configuration and FHiCL for flexible runtime settings. Addressed integration and performance challenges by refactoring namespaces, optimizing FFT routines, and standardizing configuration management. Enhanced data quality and maintainability through careful documentation, repository hygiene, and migration of calibration constants to external configuration. Improvements to channel mapping, error handling, and modular code organization supported reliable simulation workflows and streamlined onboarding for new contributors in scientific computing environments.

February 2026: Delivered Photon Calibrator Configuration and Calibration Constants Management for ProtoDUNE in DUNE/duneopdet. Integrated remote feature changes, added SPE calibration constants configuration, migrated hardcoded constants to external FHICL configuration, and ensured ProtoDUNE SP workflow compatibility. These changes improve calibration accuracy, configurability, and maintainability, while preserving workflow stability.

November 2025 monthly summary for DUNE/duneopdet: Delivered Raw Waveform Analysis Output Enhancement and Build System/Code Organization for RawWaveformAna, with groundwork for PROLOG integration. Key improvements enable processing PD VD raw data with FHiCL configuration, output as ROOT TTree with raw data, and inclusion of event trigger types in waveform analysis. Codebase reorganized into dedicated Ana directory with new CMake setup to improve maintainability and build reliability.

During October 2025, I delivered a feature to configure FFT transformer optimization in the Deconvolution module of duneopdet, enabling performance improvements for long waveforms by adjusting ROOT FFT object instantiation. This was complemented by a bug fix in duneprototypes for APA1 PDS modules where the channel map endpoint links were incorrectly configured; correcting the mappings ensures accurate data routing for multi-link endpoints. Together these changes improve processing performance, data integrity, and overall reliability. Skills demonstrated include performance-driven configuration design, ROOT/FFT integration awareness, cross-repo debugging, and git-based change management.

February 2025 monthly summary for DUNE/duneopdet: Completed a critical namespace refactor to prevent conflicts with the larana OpticalDetector OpHitFinder. Implemented renaming of the OpHitFinder namespace from opdet to duneopdet across multiple C++ files. The change was implemented in commit 41ec728246d0cbdacc22b6401963ae104d05575b. This work enhances build stability, reduces integration risk with the larana stack, and clarifies module boundaries while preserving API compatibility.
