01 · OVERVIEW

#What is saiyouba

saiyouba is the candidate-first engineering platform that combines LinkedIn + GitHub + Calendly + HackerRank — but built around you. Create one living profile you fully own. Control exactly who sees it and what they see. Securely share private GitHub projects without making them public. Connect your Google Calendar so recruiters can book interviews directly into your available slots. Companies evaluate you on real work and recent activity instead of paper resumes. No more rewriting resumes for every company. No more back-and-forth scheduling. Just real skills, real control, and faster connections with companies that actually match.

For candidates

Own a profile that goes beyond a résumé — including what you're building right now — and share it by a single link with only the people you choose.

For recruiters

Find candidates you're interested in and, with Google Calendar, book a casual interview straight into an open slot.

03 · WHAT YOU OWN

#What you get on day one

You don’t wait for a company to show up. The moment you sign up, three things are yours: a living profile built from your GitHub and résumé, an AI skill report generated from six months of your real activity, and a Japanese-format 履歴書 you can generate straight from that profile. None of it depends on anyone hiring — it’s a record of your work that you keep.

# AI skill report — built from your real GitHub activity, never self-reported
source:        github
window_months: 6
languages:     [ Go 41%, TypeScript 33%, Python 12% ]
dimensions:                          # 0–100 per axis, each with a rationale
  - { label: "Code quality", score: 82 }
  - { label: "Testing",      score: 74 }
  - { label: "Consistency",  score: 88 }
archetype:     "Backend-leaning full-stack"
level:         "Senior"
# private repos you grant access to are included, but anonymized

04 · PRIVATE CODE

#Showing private work

Your best work is often the side project you can’t make public. saiyouba shows that private code inside your profile, behind a password you set — the repo stays private on GitHub. You share the password over in-app chat, and here’s the part that matters: before you hand over the key, you can already see the recruiter’s company, their profile, and the role. You decide with full context. You hold the key.

project:  side-project
repo:     github.com/you/side-project    # stays PRIVATE on GitHub
in_app:   password_protected_view         # renders in-app, behind YOUR password
unlock:   recruiter enters the password you shared in chat

before_unlock:                            # the visibility is mutual — it favors you
  you_see:   [ company, recruiter_profile, role ]
  they_see:  nothing_of_your_code
the password-gated state (real behavior)
05 · SHARE CONTROL

#Who sees you, and for how long

One profile, one link — but you set the terms. A share link can be recruiter-only or public. Public is read-only and code-gated: no code renders without an authenticated recruiter. You set an expiry — 12 hours, 24 hours, 30 days, or a custom window — and you can revoke and reissue at any time. You can block your current employer’s email domains so a leaked link still can’t get in. And you see who viewed you.

# your share link — you hold every control
visibility:      recruiters_only          # or: public (read-only)
expires_in:      24h                       # 12h · 24h · 30d · custom
code_access:     authenticated_recruiter   # never renders for anonymous / public
blocked_domains: [ your-employer.co.jp ]   # a leaked link still can't get in
status:          active                     # revoke / reissue anytime
viewers:         visible_to_you             # you see who opened it
your share-link controls (real behavior)
06 · INTERVIEWS

#Getting interviewed

When a fit is real, there’s no email tennis. A recruiter sees your open Google Calendar slots and books one directly — it lands in your calendar instantly, no “please send three dates.” Take-home tasks, coding tests, and system-design sessions run on a real-time shared document right in the app, so you show ability objectively instead of spinning up yet another tool. And a pipeline calendar keeps every company and every stage in one view.

THE BROKEN SYSTEM[3/10]

You're judged on paper, not ability.

A paper résumé screens you out, and the process moves on without anyone ever reading your code. Weeks lost to scheduling alone. Then "not what I imagined after joining" hits the company and the candidate alike. Mismatch doesn't shrink — and that's not your fault, it's the system's.

Weeks

Weeks to a single interview

Send three dates, wait for a reply, open a link, wait again. The email back-and-forth of scheduling alone takes weeks to reach a first interview.

0 lines

Your code goes unread

Screened out by a paper résumé and keywords. The outcome is decided without anyone ever reading the code you actually wrote.

Both

Both sides feel "off"

People join before either ability or real preferences come across. So both the company and the candidate are left with a "not what I imagined" mismatch after the start date.

The payer

Built for whoever pays

On most hiring services, the paying company is the star. Candidates are treated as something to be delivered — never built to be judged fairly on real ability.

Weeks to an interview, just from scheduling emails — with saiyouba, seconds.

FROM PAPER TO LIVING[4/10]

What reaches companies is the living you.

Rewrite your résumé for every company, export it to PDF, send it — and it's stale the moment it leaves your hands. Paper just can't capture an engineer's real ability. On saiyouba, companies see the code you wrote today and what you're working on right now, as-is. Your ability comes across accurately, so mismatch rarely happens.

BEFORE

Write it, send it, write it again.

EVERYTHING IN-APP[5/10]

Everything it takes to get hired on merit — all inside one app.

No external links, no email back-and-forth, no separate accounts for other tools. Everything you need to show your real ability and meet the right companies faster, gathered in one place.

Feature 01Available

Get judged on your real, working code.

The ability a paper résumé can't convey is obvious the moment someone reads the code you wrote. Even code in a private repo shows up right on your profile in a password-protected view. No making your GitHub public, no sending links. Companies read your working code and judge you on real ability.

  • Keep the repo private — show only the code
  • Password-protected — only the person you share with can open it
  • Companies evaluate real ability, not a résumé

Your working code proves your ability before the interview even starts.

Feature 02Available

Your GitHub, turned into a skill report.

AI reads your real activity over the last six months — commits, language mix, even per-axis scores — and generates a skill evaluation report companies grasp at a glance. Public repos and the private ones you grant access to are both included. Nothing inflated, never stale — the evidence is always your code, now.

  • Verified on real data from public + private repos
  • Commits, language mix, and per-axis scores, auto-visualized
  • Can't be inflated, never goes stale — backed by your code

AI builds your skill report from the last six months of real activity.

Feature 03Available

Scheduling with zero back-and-forth. Confirmed in seconds.

No more "please send three possible dates" emails, no more opening a scheduling link, thinking, picking, and waiting again. Recruiters see your open slots and just book one. The confirmed meeting lands in your Google Calendar instantly.

  • No one asks you for candidate dates anymore
  • No external scheduling links to open
  • Synced to Google Calendar the moment it's confirmed

Recruiters book your open slots directly — you just get the notification.

Feature 04Available

See where every process stands, at a glance.

Upcoming interviews, finished interviews, and how far each process has progressed. The status of every company you've applied to is all visible from one calendar. Job hunting run across ten inboxes and a spreadsheet is a thing of the past. You'll never lose track of where you stand.

  • Upcoming plans, past interviews, and progress at a glance
  • Jump straight to recruiter / company info from the calendar
  • All your process status, consolidated in one calendar

When you can see where things stand, your next move is never in doubt.

Feature 05Available

Share in one click. The control stays with you, always.

Issue a protected share URL and hand it only to the people you choose. Change your mind? Revoke or reissue it anytime — you need no one's permission to cut off access. The key to your profile is 100% in your hands. Every recruiter and company reaches it through the same single URL.

  • Issue, revoke, reissue — all done by you alone
  • You can see who viewed it
  • One single URL reaches every recruiter and company

From issuing a link to revoking and reissuing it — control always stays with the candidate.

Feature 06Available

Your Japanese 履歴書, straight from your profile.

No more rewriting a résumé for every company. saiyouba builds a Japanese standard-format 履歴書 from your profile and shows it right inside the app. Your living profile is the source of truth; the résumé is simply another view of the same information, in the format everyone here knows.

  • Auto-filled straight from your profile data
  • Follows Japan’s standard 履歴書 format
  • View it in the familiar résumé format, right in the app

Your profile is the source — the same information, in 履歴書 format.

Feature 07Available

Take-home tasks and coding tests, all right here.

Coding tests, system design, interview prep. You discuss them right inside a real-time shared document. Because you can show your ability objectively, evaluation gets fairer. And being forced to spin up an account on yet another tool for every process — that ends here.

  • In-app coding tests and system-design tasks
  • Candidate and recruiter edit the same document together
  • Interview-prep content in the same place

From interview prep to tests — all inside the app.

OUR STANCE[6/10]

A candidate is not a product.

1We never charge engineers a single yen.

saiyouba earns from the company side. Candidates get no feature limits, no hidden fees, no "pay to rank higher." Free, forever.

2We never hold your profile hostage.

Issuing or revoking a share link is one action — yours. Export your data anytime, leave anytime. We don't build a business on lock-in.

3By your "now," not old paperwork.

What deserves evaluation is the code you wrote today and what you're learning now — not a résumé from eight months ago. That's why a profile has to be alive.

FAQ[9/10]

Frequently asked questions.

No. Beyond your work history, companies can see the code you've actually written (private repos included, shown in a password-protected view on your profile), your GitHub activity, and what you're working on now — and judge you on real ability. That cuts mismatch on both sides: theirs (hiring the wrong person off paper) and yours (joining a company that turns out wrong).

AI generates a skill evaluation report from your real activity over the last 6 months — commits, language mix, and repositories. It covers your public repos plus any private repos you grant read access to (private-repo data is anonymized; your code is never made public). Because it's backed by what you actually built rather than a self-reported skill sheet, companies grasp your ability at a glance — and since activity auto-syncs, the report always reflects your "now."

When you create your profile, you can list company email domains we'll block from viewing — so even if your link leaks, they won't get in. saiyouba is built like GitHub or LinkedIn for engineers: a long-lived showcase you keep updating whether you're job-hunting or not, so the profile itself never signals "looking right now."

Engineers in Japan have legacy ATS portals on one side and English-first global sites on the other. saiyouba is the missing third option — JP-native, live, candidate-first.

Your GitHub activity auto-syncs. If you can't open the app every day, a weekly "what did you work on?" nudge lets you keep the profile current in 3 minutes.

Yes. saiyouba generates a 履歴書 in Japan's standard format from your profile and shows it right inside the app — no rewriting it for each company. "No more paper résumés" means you're freed from rewriting documents over and over: your living profile is the source of truth, and the résumé is simply another view of the same information, in the format everyone here knows. Enter your information once, and you can see it in 履歴書 format anytime in the app.

First, candidates control whether they accept inbound messages at all — recruiters can only reach you when your job-hunting status is set to "looking." Recruiters go through verification on our side, so we filter spam before it reaches you. If anything slips through, you can report a recruiter or company directly — we review every report and take action.

Yes, of course. saiyouba is a Japanese-first hiring platform — Japanese is the preferred working language, though anyone is welcome to use it. Every field carries both JP and EN labels, so the same profile works for English-speaking teams too.

Yes. The "preferences" section on your profile is free-form text — write any work style you want (remote, hybrid, on-site, contract, side gigs, anything). You only hear from companies that match what you've written.
