Working with Inna is a great pleasure and a rare case where the client understands the subject at an expert level. The project was serious: an optimization MILP model of a solar station with an energy storage system plus a full investment model (NPV/IRR/DCF, sensitivity analysis, bilingual report of 30+ pages). Inna provided detailed, structured feedback on each sheet — thanks to such standards, the final report turned out to be at a level "ready to present to an investor," and it was a joy for me as the performer to take it on. All agreements were honored, payment through Safe was prompt, and communication was clear and respectful. The stage has been fully completed, and we continue to collaborate on the next ones. I recommend her 100%!

I am completely satisfied with the collaboration with Inna. The client quickly got in touch, promptly reserved payment through Safe, provided all necessary materials, and carefully reviewed the results.

The project was technically complex — a MILP model for PV/BESS, dispatch, energy flows, curtailment, financial summary, sanity checks — so it was especially important that the client provided not just a formal acceptance of the work, but quality technical feedback on the substance. All clarifications were constructive, without chaos and without "do everything again just in case."

I recommend Inna for collaboration as a responsible and engaged client. I would be happy to continue working on the next stages of the project.
10/10.
