How do you test a calculation without running the whole app?

Shop Inventory & Sales Management System

A multi-tenant inventory and POS system connecting stock movements, financial records, and role-based access. Built with Next.js and TypeScript, with business logic separated into domain modules and calculation functions that can be unit tested independently.

Contribution: Fullstack Developer
Built with: Next.js 14, TypeScript, Prisma ORM, PostgreSQL, Vitest

Look inside this system

Stock movements, financial records, and access permissions meet in one application. Read the work through its workflow, business rules, calculations, and data changes.

The workflow
Inventory and POS workflows connect stock movements with financial records.
The rules
Domain modules separate business logic from facades and database queries.
The calculation
Pure calculation functions can be unit tested independently.
The data changes
Prisma transactions group related database changes.

How does a sensor reading become something people can use?

Clean Water Monitoring

Final-year project connecting water-quality sensors to a real-time dashboard. MQTT feeds Firebase; React and an Express API support location maps, issue reporting, and separate LINE LIFF and admin authentication flows.

Contribution: Fullstack Developer / IoT Developer
Built with: React, Node.js, Express, Firebase Realtime Database, MQTT

Explore the project

Look inside this system

This final-year project connects water-quality sensors to a dashboard and a service-point map. The story continues in the automated checks built around the same system.

Sensors
Sensors measure pH, TDS, turbidity, and temperature.
MQTT
MQTT carries the sensor readings to the data service.
Firebase
Firebase Realtime Database stores and syncs those readings.
Dashboard
The React interface presents water readings alongside service-point locations.

How does a test become a reviewable record?

Automated Testing for Clean Water Monitoring

API, admin UI, and end-to-end testing for Clean Water Monitoring with Playwright. A custom Node.js pipeline checks server health before tests, exports CSV and JSON results, and uploads reports to Google Sheets. Tests use Page Object Model and environment-specific configuration.

Contribution: Automation Tester
Built with: Playwright, TypeScript, Node.js, GitHub Actions, Google Sheets API

Explore the project

Look inside this system

The Clean Water Monitoring test project connects API, admin UI, and end-to-end checks with execution scripts and report exports. Follow the path from a server check to a shared report.

Check readiness
A Node.js pipeline checks server health before test execution.
Exercise behavior
Playwright checks API, admin UI, and end-to-end flows.
Export results
Scripts export execution results as CSV and JSON.
Share the report
The pipeline uploads reports to Google Sheets.

Development
meets testing.

My work combines full-stack development and software testing: a multi-tenant inventory system with testable calculation logic, an IoT monitoring dashboard, and API, admin UI, and end-to-end checks with Playwright. These projects show both how I build a system and how I verify its behavior.
