Excel automation built on real engineering, that's the difference.
I'm an energy analyst and Excel specialist with 9 years of power plant operations, PVsyst and RETScreen expertise, and a published research background in energy and sustainability.
Most Excel specialists learn the tool. I used it to run a 62 MW power plant.
For six years as a Performance & Efficiency Engineer at a biomass cogeneration facility, Excel wasn't a reporting tool, it was the operational backbone of daily performance monitoring, KPI tracking, fuel management, and plant reliability analysis. I built the systems, ran the numbers, and made engineering decisions based on them. That background is what I bring to every project.
I now work exclusively as a remote analyst, combining advanced Excel automation with energy domain expertise that most data freelancers simply don't have.
📊 Excel Automation & Data Analytics:
This is where most of my client work lives, building tools that run themselves, dashboards that don't need a manual, and data systems that give decision-makers what they actually need.
Excel Automation & VBA: Automated reporting pipelines, dynamic tools, error-proofed workflows built for daily operational use.
Power BI Dashboards: Engineering KPIs, operational performance tracking, ESG and sustainability reporting.
Power Query & Data Modeling: Structured, clean data architecture that makes every downstream analysis faster.
Python (pandas) & SQL: Data cleaning, ETL pipelines, large dataset processing and reporting automation.
ESG & Social Value Analytics: Built a Social Value Calculator and reporting framework covering 3,000+ outcome datasets for a UK-based social value consultancy.
⚡Renewable Energy Modeling & Feasibility:
I produce energy models that hold up when a developer, lender, or investor looks at them closely, because I've worked inside the systems I now model.
Solar energy yield assessment using PVsyst: System design, P50/P90 generation estimates, shading analysis, bankability-ready outputs
Energy feasibility studies using RETScreen: Cost sensitivity analysis, GHG quantification, IRR and payback modeling for renewable and efficiency projects
Heating and cooling load calculations to ASHRAE standards: accurate peak load sizing for energy-efficient system design
Power plant performance analysis: Combined Cycle, Open Cycle, and Rankine Cycle configurations using structured data models
Energy efficiency project analysis: Savings quantification, investment justification, operational benchmarking.
I'm currently expanding into full techno-economic and project financial modeling, LCOE, project IRR, and DSCR analysis for renewable energy investments, as a natural extension of the feasibility work I already deliver.

MS, Thermal Power Engineering, UET Lahore (Grade A)
BSc, Mechanical Engineering, UET Lahore (Grade A)

🔧 Tools:
Microsoft Excel · VBA · Power BI · Power Query · Python · pandas · SQL · PVsyst · RETScreen · eQuest · ASHRAE Load Calculations
If your project needs Excel, built by someone who understands the engineering behind the data, or energy analysis grounded in real plant experience, send me a brief description of what you need. I'll give you a straight answer on whether it's a fit.
