New: timezone-aware proposals.
Click the timezone picker, type your country or city, choose your local timezone — and EigoPropo instantly saves it to your profile and uses it in every proposal so clients always know where you’re based.

Instantly get a focused list of the skills clients actually care about.
This is the skill search inside EigoPropo — my AI proposal tool for non-native freelancers.

“I'll fix this UI real quick.”
Two hours later:
Why do tiny layout tweaks always turn into boss fights?
Anyway, it looks perfect now.
Building a proposal generator for non-native devs.
Beta soon 👀

I fixed one line and somehow everything broke.
So I'm going for a walk.

While adjusting the profile UI/UX,
the card suddenly stretched vertically 😂
Who told you to grow like that?!

Been building a small AI tool for freelancers, solo.
Simple UI, fast output, designed to make the “proposal part” of freelancing hurt a bit less.
More screenshots soon.

I built an LP for my new tool, and here’s the funny part:
I keep telling everyone, “AI writes proposals in minutes,”
but the layout, the flow, and the wireframes?
Yeah… all of that was still made the old-fashioned way by one very analog human — me. 😇

Setup diary: integrating Stripe Connect Express
Hour 1 — test-mode KYC?!
Hour 3 — UI labyrinth
Hour 6 — error parade
Day 2 — doc deep dive
Day 3 — shipped! 🎉
Lesson: keep going. Also, I’m wiped out.

Sept 23 — Shūbun (Autumnal Equinox).
Day and night are equal, balance of light and dark. 🌅🌕
In Japan it’s a day to honor ancestors—not religion but gratitude.
Day is human, night sacred. When equal, the two meet.
My Waka app: capture this spirit in design.

The real challenge in building my Waka app lies in strengthening the UI.
At the end of the day, it’s all about design. I’m still learning, but my goal is to translate the beauty of Japanese culture into modern UI.
How much atmosphere can I capture in a single Waka card?

Studying seasonal design at the library.
Hakuro (White Dew, Sept 7–22) is expressed with:
・transparent colors
・dew drops as motifs
・silence through empty space
It’s simple in words, but tough to bring into UI.

Man, this sucks…
I can’t focus, I can’t code.
I kept checking my work over and over, losing my sanity.
And the culprit was—
“The Neighbor’s Drill Construction.”
Come on, seriously?
I just want to code in peace!!!
