Hi, I'm Daria

I am a scientific Python developer and computational neuroscience researcher. I build tested data pipelines, ML evaluation workflows, and reproducible research software for complex time-series and neurodata.

My work combines software delivery with research practice: reproducing difficult bugs, turning analysis code into maintainable packages, implementing validation and quality-control workflows, and documenting the assumptions behind numerical results. I have a Master's degree in Psychology with Distinction from HSE University's Cognitive Sciences and Technologies programme, with training in EEG/ERP methods, neuroimaging, neural modelling, statistics, and experimental design.

I am available for remote contract and part-time work in scientific Python, ML evaluation, research software, and data pipelines. I am also open to research software, research-assistant, predoctoral, and PhD roles in Vienna.

What I can help with

  • Scientific Python and research software — refactoring notebooks and scripts into tested packages, command-line tools, and reproducible workflows.
  • ML and model evaluation — data alignment, validation design, appropriate metrics, error analysis, uncertainty reporting, and regression tests.
  • Data pipelines and quality control — time-series processing, structured metadata, traceable decisions, provenance, and automated reports.
  • Debugging and upstream contributions — minimal reproductions, numerical and API-safe fixes, focused tests, CI, and technical documentation.
