Ivan Kashuba

Materials & Polymer R&D professional with hands-on experience in powder coatings, monomer production, thermal analysis, optical materials and laboratory process troubleshooting.

Focus areas

  • Scientific data analysis and engineering calculations
  • Materials, polymers, coatings and monomer processes
  • Process troubleshooting and technical documentation
  • Python and Excel for reproducible calculations
  • Introductory computational chemistry and bioinformatics coursework

Selected project

  • AI Laboratory Document Automation
    UiPath and FastAPI automation for laboratory document analysis, specification validation and human-review routing. Demonstrates tested PASS, REVIEW and FAIL workflows with C# Coded Workflows, REST/JSON, SQLite and automated tests.
  • Reactor Dissolution Calculation
    Parameter-driven Python model for evaluating salt dissolution in a stirred reactor using engineering correlations and scenario-based calculations.
  • Pneumatic Dryer Performance Calculator
    Parameter-driven Python model for evaluating pneumatic tubular drying performance across a gas-velocity range.
  • Stirred-Vessel Heating Comparator
    Parameter-driven Python model comparing theoretical heat-transfer performance for paddle, anchor and propeller impellers in a jacketed stirred vessel.
  • Tube-in-Tube Heat Exchanger Scaling Model
    Python model converting an Excel-based tube-in-tube milk-heating calculation into a reproducible workflow with coursework validation, criteria-based flow screening and improved heat-transfer assumptions.

Background

My work combines practical laboratory and production experience with structured analysis of experimental data, quality deviations and process conditions.

I have worked with powder coatings, biodegradable monomer production, thermal-vacuum processing, NMR, DSC, FTIR, spectrophotometry, optical coatings and infrared light-guide technologies.
