Buy Kaito Oka a coffee

I'm a solo founder & CTO of VizAna Data Inc. based in Yokohama, Japan.

I build lean, end‑to‑end data systems that turn raw numbers into business insight.

🚀 Custom web & API solutions (TypeScript / AWS)

📊 Analytics pipelines & modern data platforms (dbt, Snowflake, Redshift)

🤖 Practical AI & LLM integrations for real‑world products

My daily routine ranges from writing serverless back‑ends to helping clients design, build, and operate data pipelines, ML models, and AI‑driven applications. If you’ve found any of my tech tools, articles, or side‑projects helpful, consider buying me a coffee and keep the gears running ☕️

Every cup fuels new experiments and knowledge‑sharing—thank you for your support!
