Worked on the Multi-Energy-Systems-Optimization/mesido repository, delivering features and fixes that advanced energy systems modeling, cost analysis, and optimization. Developed and refined asset models for heat pumps, boilers, and photovoltaic systems, integrating technical lifetimes, cost attributes, and time-series constraints to improve simulation accuracy and lifecycle cost projections. Enhanced backend reliability through robust error handling, database integration, and expanded automated testing. Used Python, ESDL, and data modeling to support optimization workflows, KPI-driven reporting, and traceable data outputs. The work enabled more accurate capacity planning, investment-cost minimization, and business insight for energy network deployments, demonstrating depth in backend and analytical engineering.
