Works
Public website works and technical development assets presented as problem-solving case studies.
We present our work as problem-solving cases, not just a list of URLs.
Each case explains what kind of issue existed before the consultation and what we organized or built. Please use these examples as a reference when considering a request.
Technical Development
System Development Work
In addition to website production, we design and develop operational systems such as cloud-native foundations, business systems, authentication foundations, email and DNS management, and development automation. Public development assets can be reviewed on GitHub. For private projects, we introduce technical areas and business issues solved without disclosing customer information or confidential details.
These development records are examples of projects we have designed or developed. Public repositories are projects actively developed and released by us. Private projects cannot disclose details due to customer requirements or confidentiality, but their technical areas and solved issues are summarized.
Business system development / Authentication and security
Inquiry and Email Sending API Foundation
A small API foundation that safely receives inquiries from static sites and sends email.
GoCloudflare TurnstileFirebase App CheckDocker
- Provides a low-cost inquiry flow with spam prevention
- Enables form submission even from static sites
- Reusable across multiple sites

Business system development / Authentication and security / Database management
Authentication Gateway for phpMyAdmin
A gateway that assigns database connection information based on user permissions and safely signs authenticated users into phpMyAdmin. It does not return database passwords to the browser and integrates with phpMyAdmin signon authentication using short-lived one-time tickets.
GoSveltephpMyAdminSQLiteMySQLRedisDockerKubernetes
- Allows administrators to manage phpMyAdmin access without sharing DB passwords individually
- Controls available DB connections by user or group
- Improves database management security through password encryption, short-lived tickets, and audit logs
- Can scale from a single-container setup to multi-pod setups using MySQL and Redis
- Supports Kubernetes Secret and bootstrap settings for easier production deployment

Cloudflare Turnstile / Firebase App Check Gateway
A Go gateway that verifies Cloudflare Turnstile tokens on the server side and exchanges them for Firebase App Check custom provider tokens. It provides separate token exchange APIs for frontends and App Check verification APIs usable with Traefik forwardAuth.
GoGinCloudflare TurnstileFirebase App CheckFirebase Admin SDKTraefik forwardAuthDockerGitHub Actions
- Introduces spam prevention and API protection at low cost for static sites and small web apps
- Combines Cloudflare Turnstile and Firebase App Check to allow access only through legitimate frontends
- Adds an authentication and verification layer in front of existing APIs through Traefik forwardAuth
- Reusable for inquiry forms, member APIs, and other flows where bot access should be reduced
- Supports Docker, health checks, environment configuration, and automated releases

michibiki.io site foundation
An internal site foundation combining Hugo, an inquiry form, and container-based delivery.
HugoDockerTypeScriptGitHub Actions
- Easy to deliver quickly as a static site
- Inquiry form separated as a React component
- Containerization makes deployment to cloud environments easier
Private Project
Cloud-native business foundation for small businesses
A foundation integrating web, email, authentication, and backups for small businesses.
KubernetesAnsibleGitOpsTraefikPostgreSQLMySQLMariaDBLonghorn
- Operable at low cost
- Can add functions as needed
- Secures backup and recoverability
Cloud-native foundation
We design operational foundations using Kubernetes and containers, from low-cost configurations to future expansion.
Services can be scaled down or up according to business size as users and workloads change.
GitOps / IaC / CI/CD
GitOps, Infrastructure as Code, and CI/CD make builds reproducible and reduce dependence on individual operators.
Downtime during recovery, migration, and changes can be minimized while operating safely.
