About Seiko
I help businesses transform inefficient workflows into scalable systems.
With over 20 years of experience in business operations, process improvement, and IT, I specialize in optimizing back-office workflows through automation and practical AI adoption.
My expertise includes Excel VBA, Power Query, Google Apps Script, workflow automation, data validation, and AI-powered business solutions using ChatGPT and Claude.
Rather than simply building tools, I focus on understanding business processes, identifying bottlenecks, and designing systems that reduce manual work, improve data quality, and enable sustainable operations.
I have experience supporting academic publishing, education, administration, HR, logistics, and small business operations.
If you're looking for someone who can bridge business and technology to create practical, scalable solutions, I'd be happy to help.
