Razin Mujtahid Choudhury

Mechanical Engineering BSc student at Boğaziçi University, specializing in Thermal Systems.

Interested in thermal-fluid systems, engineering analytics, operations, optimization, and using data-driven methods to connect technical performance with business impact.

Featured Projects

Developed a thermal–economic maintenance optimization framework for a counterflow shell-and-tube heat exchanger.

  • ε–NTU thermal modeling and asymptotic fouling degradation
  • Cleaning-cost and downtime optimization over a 180-day operating horizon
  • 108-scenario analysis covering fouling severity, cleaning effectiveness, energy price, and maintenance cost
  • Thermal–economic decision framework balancing cost and retained thermal performance
  • Sensor-based estimation of heat duty, overall heat-transfer coefficient, and fouling resistance
  • Conceptual SolidWorks heat-exchanger design and technical report

Key result: A two-cleaning base-case strategy reduced cumulative thermal loss by 19.03% relative to the strict cost optimum for only a 0.025% increase in modeled cost.


Developed an Excel and Power BI manufacturing-performance analysis using 1,656 production records across multiple production lines, shifts, and products.

  • Production KPI development and performance analysis
  • Excel PivotTables, dashboards, and savings modeling
  • Interactive Power BI dashboard
  • Line- and shift-level efficiency and cost analysis
  • Financial impact estimation and executive recommendations

Tools: Excel, Power BI, data analysis, KPI development


Developing an automated waste-sorting system combining mechanical design, sensing, embedded control, and AI-assisted waste identification.

Current work includes:

  • SolidWorks mechanical design and system architecture
  • Waste-routing and sorting-mechanism development
  • Repository documentation and project organization
  • Preparation for physical construction and system integration

The project is currently under development, with the physical build, control integration, and waste-classification system forming the next stage.
