Welcome
Thank you for visiting.
This site is where I — Senko, working as a freelancer — will post my work and articles.
The content will primarily cover areas I’m personally interested in: cutting-edge IT topics centered on AI, investment, and related subjects.
If any of that sounds interesting to you, feel free to leave a comment anytime.
My Background
Let me briefly introduce my background.
When I was a student, “IT engineer” wasn’t yet a well-established career path. It was around the time when former Prime Minister Koizumi was repeatedly declaring on television that “the IT revolution is coming!” — and dial-up internet was just beginning to spread. Getting online and discovering what the internet could do left a strong impression on me, and that’s what got me interested in IT.
I studied information science in university and joined a large manufacturer-affiliated systems integrator as my first job. I enjoyed building things with code as a student, but after joining the company, writing specification documents became the core of my work.
As I climbed the ladder, hands-on technical work gradually disappeared from my role. Stakeholder negotiations, project management, and team management took over — days filled with back-to-back meetings became normal.
This is a standard career progression in Japan, but it created a growing disconnect: I’d entered the IT industry because of a genuine interest in technology, and now I was spending my days almost entirely on management tasks. I started feeling more stressed than engaged.
I kept studying emerging technologies on my own, but almost none of it made it into my actual work — I spent more time maintaining decade-old systems than using anything new. The thought of doing work that didn’t require keeping my skills current started to feel unsettling.
I changed companies twice and worked at three different organizations in total. All of them were structurally the same. Realizing that this kind of career trajectory is essentially built into how Japanese IT companies work — that’s what made me decide to go independent.
The short version: I went freelance because staying employed meant doing work that didn’t interest me.
What I Plan to Do
Going forward, I intend to create articles, videos, and personal projects (tools and websites) around topics that I find genuinely interesting, exciting, or worth learning more about.
Monetizing this kind of work takes time. I expect to be drawing on savings for a while — but I have enough set aside to live on for several years without income, so I plan to take it at a relaxed pace.
My goal is to gradually build up a portfolio of passive-income content — articles, work, videos — and eventually reach a point where it covers my living expenses. If that doesn’t happen and freelancing isn’t the right fit for me, I’ll accept that honestly and look for a new job.
Either way, I’ve planned for both outcomes, so I’m not putting any unnecessary pressure on myself. I want to take my time doing what I want to do.
Looking forward to building this together. Thank you for stopping by.
