Overview

Tasukaru is a multi-tenant care-management SaaS built for Japanese welfare facilities. Care staff needed a single system for health tracking, Individual Support Plans (ISP), and post-interview documentation without drowning in paperwork.

I owned full-stack delivery spanning Next.js surfaces, FastAPI services, PostgreSQL data models, and Ory (Kratos/Keto) for identity and authorization. AI workflows turn interview audio into structured assessment fields with streaming, prompt caching, and batching to keep latency and cost under control.

The product ships containerized with Docker for consistent staging and production environments, SMS alerts for operational events, and RBAC that scales across facilities without sharing tenant data.

Overview

NipponHub consolidates several multilingual company sites into one pnpm monorepo so design systems, content workflows, and deploys stay consistent across brands.

A shared React UI library is the single source of truth for components. Editors work in Markdown through Decap CMS with localization baked into the workflow, no developer ticket for routine content changes.

GitHub Actions push static builds to S3, invalidate CloudFront, and maintain separate staging and production pipelines so releases stay repeatable.

Overview

At networking-heavy events, paper business cards still win, but typing them into a CRM is slow and lossy. CardCapture turns a photo into structured contacts in one motion.

Staff capture a card image; OCR extracts name, title, email, and company into the event roster. Event managers then send bulk follow-up or invitation email to the full intake list without exporting spreadsheets by hand.

Built as an internal Next.js / Node tooling surface optimized for live floor use: fast capture, clear confirmation, and email that can go out before the event ends.

Overview

GVS Group’s GOBI platform is the digital hub for Zustellkunden, online orders, logistics info, and service tools for system catering. The portal needed a helpdesk that felt native to Odoo, a dashboard where portal users can see live operational stats at a glance, and a customer UI that matched GVS brand language.

I implemented helpdesk ticket flows inside Odoo ERP, built a portal dashboard with live stats for customer users, and redesigned navigation, layout, and visuals so the experience aligns with the broader GVS identity instead of stock Odoo chrome.

Result: live metrics, service tickets, and day-to-day portal use sit in one branded surface at gobi.gvsgroup.de, clearer for customers, consistent with GVS marketing and operations.

Overview

Crudsmith removes the boilerplate tax when you need a working CRUD API yesterday. Install the package, declare a schema, and get a configurable Node.js server without scaffolding an entire framework.

Validation and flexible config keep the generated surface honest for prototypes, internal tools, and teaching demos, while staying small enough to publish and iterate on NPM.

Crossed 600+ downloads in the first week after publish, validating that the “declare and run” model solves a real friction point for Node developers.

Overview

Kirayapay helps landlords and operators run flats and plazas without spreadsheet chaos, tenants, contracts, and money flows live in one system with clear roles.

RBAC separates owner, manager, and staff permissions. Financial tooling and dynamic contract generation cut repeat admin work; Docker and Redis support a production-ready deployment shape.

Adopted by two companies for day-to-day property ops, with measured ~50% improvement in operational efficiency after rollout.

Overview

TabCleanser is a lightweight privacy utility: one click clears cookies across sites so sessions don’t linger longer than you want.

Built to work on both Chrome and Firefox with a minimal surface, no dashboard bloat, just a reliable wipe action when you need a clean slate.

Open-sourced on GitHub for anyone who wants the same one-shot cookie hygiene without installing a heavy privacy suite.

Overview

Arcade Machine is a personal PWA playground, classic browser games wrapped in a responsive shell you can install and revisit offline-friendly.

Built with Next.js and Tailwind to keep the cabinet feel tight on phone and desktop. Not a client product, just shipping something fun end-to-end.

Overview

Built for FAST-NUCES students preparing for placements: schedule mock interviews, keep CVs in one place, and run live sessions without cobbling Zoom + Google Drive together.

MERN stack with RBAC for candidates, interviewers, and admins. Socket.io handles real-time status; Jitsi Meet powers in-browser video rooms for practice loops.

Used by 100+ students as a campus recruitment practice pipeline, not a toy demo, a working system with roles and live video.
