To you, who opened this page

Hello,
I'm Yuta.

I work as an engineer, and in my own time I build web services by myself.

I build my ideas myself, and I run them myself after they are out.

Whether it is about work or just a small impression, feel free to drop me a line.

Yuta

Every time I make something, I print one more stamp.

When the next thing is decided, another stamp goes here.

02 — SERVICES

The kind of requests I take on.

一
Web services, from idea to launch
From the first sketch through design, development, launch and the running of it afterwards. I like shipping something small and growing it.
二
Building on AWS
Mostly serverless (Lambda, DynamoDB, Fargate), everything as code, and an eye on keeping the bill small.
三
Collecting data and making it visible
Continuous collection from external APIs, aggregation, and charts. Zawalog is that pipeline, run by one person.
