Migrating a WordPress Corporate Site to Astro + Cloudflare
We migrated a corporate site running on WordPress to an Astro static site + Cloudflare Pages. While preserving URLs, design, and SEO, it eliminates the maintenance and security burden and delivers faster page loads, AI search optimization (AIO / GEO), and AI-native content operations.
Optimizing a B2B Corporate Site to Be Cited by AI Search (AIO / GEO)
We optimized a corporate site so that generative AI—ChatGPT, Perplexity, Google AI Overviews, and others—can correctly discover and cite it. Our work spanned from AI-crawler acceptance settings, to an llms.txt that summarizes the site structure for AI, to setting up structured data.
A Whistleblowing System: One-Week Prototype in Next.js + Prisma, Then Launched as PM-Led Delivery
We built a new whistleblowing system for enterprises on Next.js + Prisma + NextAuth + Resend. With a small team of one PM and one developer, we completed a working prototype in a week and carried it through to release in roughly five person-months.
Building a tablet operations system and multi-store analytics site for a beauty-salon chain
For a nationwide beauty-salon chain, we built both the in-store tablet operations app (C#.net + WPF) and the head-office multi-store analytics site (CakePHP + MySQL) together. We integrated on-site store records and head-office management analysis onto a single foundation.
Rebuilding a large commercial-facility site on PowerCMS to withstand multi-editor operation
We built the official site and CMS for a large commercial facility with PowerCMS / PHP / JavaScript / MySQL. We designed the permissions and templates to withstand operation by multiple editors updating tenant, campaign, and store information day to day.
Building a nursing-care smartphone app plus admin console end to end with Laravel + React Native, from design through operation
For a nursing-care provider, we designed and developed both the smartphone app used by field staff (React Native) and the headquarters admin console (Laravel) as a single package. Including the AWS / Docker operating platform, we shifted field operations onto a digital foundation.
Developing and Operating "Kitei Log," a Policy-Management SaaS, In-House
We develop and operate "Kitei Log," a SaaS that centrally manages the creation, revision, dissemination, and view records of internal policies, manuals, and labor-management agreements—in-house. It lets you graduate from file-name workflows and maintain a change history that stands up to ISMS and Privacy Mark audits.
Developing and Operating "Security Sign," a Security-Work Digitization SaaS, on a Revenue-Share Model
We co-develop and operate "Security Sign," a SaaS that supports recordkeeping, report creation, and staff management for security work, with a partner on a revenue-share model. Its design fits on-site operations as they are, helping teams move away from paper-and-phone workflows.
Introducing an Organization-Dedicated AI Assistant into Google Chat
We introduced a dedicated AI assistant (bot) into everyday Google Chat, connected to internal information and tools. Inquiries and routine tasks can now be completed within the chat people already use.
AI Modernization by Introducing MCP into an Existing Service
We introduced the Model Context Protocol (MCP) into an existing service, building a connection layer that lets AI access internal tools and data safely. AI capabilities were incorporated without rebuilding the existing system.
A Statutory Recordkeeping Service for Security Companies
A service that digitizes the creation and management of the statutory records required under the Security Business Act. It brings records that tend to be handled on paper—such as guard rosters and training and instruction logs—into a single flow, from data entry to storage and output.
Integrated Synthetic Monitoring with Sentry, UptimeRobot, and Resend
A monitoring foundation that combines synthetic monitoring, error monitoring, and notification delivery, unifying everything from anomaly detection through to notifying the relevant people. UptimeRobot handles uptime and synthetic monitoring, Sentry monitors application errors, and Resend delivers the notification emails.
Building and Operating a Whistleblowing System with Guaranteed Anonymity
We built an intake and management system for internal whistleblowing that complies with the Whistleblower Protection Act. It balances reporter anonymity with separation of access privileges, providing a foundation that manages everything from intake to response records in one place.
An Employee Stress-Check and Survey SaaS, Built on Next.js + AWS Amplify + Neon
We built an enterprise employee stress-check and survey SaaS on a Next.js + AWS Amplify + Neon stack. The design balances respondent anonymity, management of aggregated results, and tenant isolation.
Expanding a SaaS Product: Refactoring and Feature Growth on Rails + MySQL
We expanded a SaaS provider's product on its existing Ruby on Rails + MySQL foundation. We untangled the front-end and admin-panel permission controls and the operations team's management load with a YAML-driven permission definition.
A Major Manufacturer's Customer-Data Batch: From Source-Code Analysis to Infrastructure Rebuild
We took on the overhaul of a major manufacturer's customer-data processing batch system. Because the incumbent vendor had lost the infrastructure environment, we analyzed the source code and rebuilt the infrastructure from scratch on AWS ECS Fargate + Python. We relaunched it as an event-driven S3 → EventBridge → Fargate architecture.
Infrastructure build and operational maintenance for a listed operating company's website replacement
As part of a TSE-listed operating company's website replacement, we handled everything from infrastructure build to operational maintenance. We set up IaC with Terraform, centralized cache and SSL management with CloudFront + ACM, and ran staging and production in parallel.
Speeding up a medical university's website infrastructure with Terraform + CloudFront
We handled the website infrastructure build for a medical university. We managed the configuration with Terraform and improved page speed with cache delivery via CloudFront + ACM, including the separation of staging and production environments.
Replacing an ad agency's budget and revenue management with an in-house web system built on Slim + MySQL
We replaced an advertising agency's budget and revenue management, moving it from Excel-based operation to a web system built on Slim + MySQL. We set up per-project budget and actuals management and cross-department aggregation as an admin console the business team can operate directly.
Building the ticket issuance and admin console for an employee-benefits service with Laravel + AWS
We developed the ticket issuance and admin console for an employee-benefits service on a Laravel / Docker / AWS stack. Covering both the administrative and build sides, we delivered an admin console the operations team can use without hesitation and a foundation that handles the whole lifecycle from issuance to redemption.
Building a booking platform for a medical corporation with Laravel + AWS, from requirements to delivery
We built a booking platform for a medical corporation on a Laravel / PHP / AWS stack, taking responsibility for requirements definition, design, and project management. The full flow of booking, confirmation, and cancellation was designed to fit the way the clinical site actually operates.
Replacing a major retailer's EC site and admin site with React + Lumen
We replaced a major retailer's EC site and admin site with a React / Redux / Lumen / Docker configuration. As PM, we handled everything from requirements organization to progress management, moving to the new platform without stopping ongoing operations.
Rebuilding an offshore-built restaurant app to in-house quality with Laravel + React + Inertia
We replaced a restaurant app and admin panel that had been developed and operated offshore, using Laravel + ReactJS + InertiaJS + TypeScript + Docker. We restored the readability of the codebase and the stability of operations.
Building a financial product application service from scratch with Laravel + Livewire
We built a major operating company's new financial product application service from the ground up with Laravel + Livewire + Tailwind + AWS. Confirmation flows, identity verification, and terms consent unique to financial products are presented in progressive steps with Livewire, without multiplying screen transitions.
Bringing security guard dispatch and control operations in-house with a React app, from planning onward
We rebuilt a security company's guard deployment and control operations—previously run on paper and Excel—into a proper business system on React + Supabase + Vercel. We were involved from the planning stage, starting with on-site interviews and designing the screens and business flows in parallel.
