About Me

I have 7 years of experience building enterprise systems for Japanese clients — spanning desktop applications, batch processing, and web/API development. This shaped my approach to engineering: I think in systems, care deeply about code quality, and take full ownership of what I build.

In early 2025, I made a deliberate pivot toward modern web development — building real-world projects with Next.js, NestJS, and TypeScript from the ground up. Not tutorials. Real use cases, real architecture decisions: decoupled monorepo, stateless auth, atomic transactions, headless CMS.

I am now seeking a Full-Stack Engineer role where I can apply both my enterprise foundation and modern stack to build products that matter.

Systems first, quality always — and never ship without asking “what happens when this fails?”

Professional Experience

Independent Full-Stack Developer

Feb 2025 – Present

Self-directed Projects

•E-commerce Ecosystem: Designed and built a full-stack platform on a decoupled monorepo — Next.js as storefront and Identity Provider, NestJS as standalone Resource Server communicating via JWKS-verified JWT tokens.
•Admin Dashboard: Built a back-office management interface with React-Admin — integrated with NestJS API for product and order management.
•Auth & Security: Implemented stateless authentication with Better-Auth, JWKS (RSA), RBAC, and short-lived client upload tokens (Vercel Blob gatekeeper pattern).
•Data Integrity: Used TypeORM QueryRunner to wrap order creation and status updates in atomic transactions — ensuring loyalty points and order state stay consistent on failure.
•Artwork Gallery CMS: Built a headless CMS platform with Payload CMS featuring a block-based layout system (Masonry Grid, Hero, Bio blocks) for non-technical curators. High-resolution artwork delivered via Vercel Blob with CDN distribution.
•Workflow: Automated CI/CD deployments via Vercel and Render. Integrated AI-assisted development to accelerate prototyping while maintaining focus on architectural integrity.
