JavaScript / TypeScript Vite Supabase / PostgreSQL Turnstile Vercel
- Problem: Move from one-off calorie estimates to personal food tracking with protected user records.
- My contribution: Defined requirements, guided AI-assisted implementation, configured authentication and database access policies, integrated Turnstile, and manually tested workflows.
- Result: Deployed a mobile-first staging prototype with calorie calculations, accounts, and food logs; conducted usability validation with three users.
React JavaScript Vite Vitest Playwright
Live web prototype · Repository
- Problem: Give cafés, bakeries, and restaurants a focused self-ordering experience.
- My contribution: Defined architecture, customer journeys, technology choices, deployment requirements, and acceptance criteria; coordinated AI-assisted implementation and manually tested ordering.
- Result: Helped deliver a functional prototype in one day and identified two defects that were fixed. POS hardware and payment-gateway integration remain pending.
Python / JavaScript Raspberry Pi NFC / GPS Firebase REST APIs
Repository · Academic capstone
- Problem: Connect fare calculation, authentication, location, seat allocation, hardware, and passenger/driver/admin interfaces.
- My contribution: Led a five-member team, developed embedded software, integrated hardware and cloud services, and troubleshot GPS instability through circuit, wiring, and satellite-acquisition software changes.
- Result: Executed tests across 21 categories and consolidated 2,188 results; 2,156 passed (98.54%).
Java JavaFX JDBC MySQL
- Problem: Keep a shared desktop application and its relational database consistent during team development.
- My contribution: Executed schema migrations across eight tables and one view, coordinated AI-assisted implementation of the Services and Prices module, and performed acceptance testing.
- Result: Identified an order-status usability defect and retested a teammate's correction to confirm resolution.
