Code-defined
The product structure lives in code, not in undocumented GUI clicks or screenshots.
Small business operations / CLI-operable tools
CLI-operable internal tools for small businesses.
I build small staff portals, reporting systems, trackers, dashboards, and internal admin tools that AI agents can create, change, test, and deploy through CLI/API workflows — delivered into your own environment.
小規模事業向けに、AIエージェントが保守できる社内専用プロダクトを作ります。
If an agent cannot build and maintain it through CLI/API, I do not sell it as a core product.
CLI-operable acceptance test
Every core tool must be code-defined, Git-managed, command-driven, testable, deployable, and reproducible by an AI agent.
CLI-buildable
Scaffolding, migrations, tests, build, deploy, and routine updates run from documented commands.
API-controllable
External platforms are acceptable only when the needed configuration and data paths are scriptable or API-driven.
Testable
Inputs, routes, forms, data rules, and critical workflows are verified before deployment.
Client-owned
Customer data and production infrastructure stay in your own Cloudflare, GitHub, or API-first platform environment.
No GUI core
Google Sites, AppSheet, and GUI-only Forms builds are not sold as durable core products.
What I build
Small internal products for owners, managers, and staff who need clearer records without buying a GUI-only workflow nobody can reproduce.
Internal staff portal
Procedures, checklists, reports, inventory notes, FAQs, manuals, and access-controlled staff pages.
Daily / field report system
Staff reports, photos, status, search, filtering, validation, and CSV export.
Checklist system
Opening, closing, cleaning, weekly tasks, completion history, and handover notes.
Inventory memo
Lightweight stock memory before a full POS, accounting, or inventory platform is needed.
Enquiry tracker
Internal intake, status, owner, follow-up date, notes, notifications, and export paths.
Small admin tool
CRUD screens, filters, permissions, exports, API bridges, and CLI-ready handover.
CLI-operable demos
Dummy-data examples of internal tools that can be read, tested, deployed, and maintained through CLI/API workflows.
Internal Staff Portal
Staff instructions, reports, and documents stop being scattered across messages, paper, and folders.
Built as a deployable internal product with dummy data, reusable content, and a structure an agent can inspect.
Internal Intake Tracker
Incoming work gets an owner, status, follow-up date, and export path.
Designed for client-owned deployment and later migration into API-first SaaS or a custom internal product.
Client-owned delivery
Your internal tool should survive beyond my involvement.
No custody
I do not turn koichinishizuka.com into your customer database or business operating system.
Your environment
Production belongs in your Cloudflare, GitHub, or API-first platform account, with clear ownership.
Exportable
Records should have CSV, JSON, API, or database paths that make migration possible.
Handover
The delivery includes enough structure for humans and future agents to maintain it.
Guide pricing
Final pricing depends on scope, existing materials, data sensitivity, access requirements, deployment environment, and cleanup needed.
Review / fix
Small code fixes, workflow cleanup, existing internal tool review, or Airtasker-sized implementation tasks.
Internal tool starter
One small workflow such as a checklist, daily report, intake tracker, or inventory memo.
Staff portal / dashboard
Staff-facing internal product with pages, forms, records, access control, and handover docs.
Client-owned deployment
Database-backed internal tools deployed into your own Cloudflare and GitHub environment.
Process
How the work happens
01
Send the problem. Tell me what is messy, repeated, fragile, or too dependent on manual GUI work.
02
Apply the CLI test. If an agent cannot create, update, test, and deploy it through CLI/API, I do not treat it as the core build.
03
Build and verify. I implement a code-defined version with tests, deployment notes, and dummy-safe examples.
04
Deploy and hand over. We move the tool into your environment with README, schema, routes, limitations, and next steps.
