About me
I help businesses turn repetitive Excel and CSV tasks into reusable Python workflows, and help technical teams understand GNSS and RTK test data.
My work includes file cleaning and merging, report automation, API integration, and positioning-data analysis. I have developed a GNSS analysis application and have experience in RTK software development and field evaluation.
Expect clearly agreed inputs and outputs, practical deliverables, and concise documentation. Send me a sample and the result you need so I can confirm the scope. Based in Japan; English and Japanese communication.
