Hi there.
I just read your posting.
Sounds like you are looking for a full-stack developer who is familiar with dashboard, energy production data, csv, excel.
As a senior developer, I have rich experience in website development.
I am very proficient in table, chart and csv, excel and so on.
I think the following is needed to build dashboard website as your requirement.
Backend: PHP framework Laravel
Frontend: React
Database: MySQL or MongoDB
The data is so large or not? We can use MySQL or MongoDB according to your data's kind.
DevOps: Git, Docker, Kubernetes, CI/CD pipeline, AWS.
You can check the website development courses.
Please contact me and discuss the project.
Best Regards.
