SHIPPED FULL-STACK PROJECTS (AI-ASSISTED & AGILE DELIVERY) — Flagship Internal SaaS (End-to-End AI-Built)

CafeTime — Internal SaaS for shift scheduling, attendance & automated payroll

Internal Tool / SaaS
Problem: The coffee shop tracked shifts with paper notes and spreadsheets, causing errors in split/night hours and 2-3 days of monthly payroll work.
Solution: Managed delivery across iterative Agile sprints and used Cursor + Claude to build a full-stack web app end-to-end: 1-tap mobile clock-in, Google OAuth role permissions, and automated split/night shift wage calculation.

Impact: Cut monthly payroll calculation time by 90% (from 2-3 days to under 15 minutes) and eliminated wage disputes completely. Active in daily production.

SHIPPED FULL-STACK PROJECTS (AI-ASSISTED & AGILE DELIVERY) — Real-time Web App & E-Commerce Platforms

GoldCar12 — Real-time fleet dispatch & shift revenue reconciliation platform

Real-time Web App
Problem: Drivers swapped customer rides informally via messages, creating messy debt records, missing trip details, and confusing shift-end settlements.
Solution: Standardized dispatch operations and built a real-time full-stack web app on Firebase Firestore: dispatchers assign rides in seconds, drivers accept trips on mobile, and the system settles commissions automatically.

Impact: Reduced dispatch time from 3-5 minutes to under 10 seconds; eliminated paper logbooks and bad internal debt across the fleet.
