Sabir I.

I build Microsoft Excel automation and custom Excel-based tools for business, along with energy data analysis, energy efficiency work, sustainability analysis, and renewable energy pre-feasibility and feasibility studies. My work combines 9+ years of professional experience across the power sector and ESG consultancy with advanced Excel, VBA and practical engineering analysis. For six years, I worked in Performance & Efficiency at a 62 MW biomass cogeneration power plant, where I used operational data to monitor KPIs, evaluate equipment and plant performance, identify inefficiencies, and support operating decisions. Later, I worked remotely with a UK-based ESG consultancy and developed ESG and SDGs tools in Microsoft Excel. Today, I help clients turn manual spreadsheets, complex calculations and raw data into reliable working solutions.
