Hands-on experience in Sprint planning, Backlog grooming on Jira/Trello, cross-functional coordination (PM/Design/QA), and milestone ownership.

Shipped Work

Real Products in Production

Software built from genuine operational needs, tested on real devices, and solving concrete frontline problems.

01Internal Tool / SaaS• Product Manager & Builder

In Daily Production

CafeTime

Internal SaaS for shift scheduling, attendance & automated payroll (End-to-End Delivery)

90%

Cut monthly payroll calculation from 2-3 days to under 15 minutes, eliminating hour disputes completely.

Frontline Friction

The cafe relied on paper timesheets and manual spreadsheets, causing errors in split/night shift hours, wage disputes, and 2-3 days of monthly reconciliation.

Product Solution

Managed the full delivery lifecycle across iterative Agile sprints and used an AI-Native workflow (Cursor + Claude) to build a full-stack web app: 1-tap mobile clock-in, Google OAuth role permissions, and an automated payroll calculation engine.

Key PM Actions & Rollout

—Captured frontline requirements, wrote PRD/User Stories, prioritized the Backlog, and configured AI context rules (.cursorrules)
—Leveraged Claude & Cursor to implement Next.js architecture, Google OAuth, and role-based access control
—Engineered and verified complex wage calculation formulas covering split shifts, night hours, and bonuses per milestone
—Performed AI-assisted refactoring, real-device mobile UAT, and staff onboarding
—Deployed to production on Vercel with automated CI/CD and managed ongoing operations

02Real-time Web App• Product Manager & Builder

In Daily Production

GoldCar12

Real-time fleet dispatch & automated shift revenue reconciliation platform

< 10s

Ride dispatch time dropped from 3-5 minutes to under 10 seconds, eliminating manual notebooks and bad debt.

Frontline Friction

Drivers swapped customer rides informally via chat, resulting in messy debt ledgers, lost trip records, and confusing shift-end settlements.

Product Solution

Standardized the dispatch workflow and built a full-stack real-time platform powered by Firebase Firestore: dispatchers assign rides in seconds, drivers accept trips on mobile, and the system settles commissions automatically.

Key PM Actions & Rollout

—Analyzed operational bottlenecks, defined the Product Roadmap, and scoped the core MVP Backlog
—Designed NoSQL collections in Firebase Firestore for instant real-time state synchronization across devices
—Used Cursor & Gemini to build high-contrast mobile screens optimized for 1-tap driver interactions
—Implemented and rigorously tested automated fee deduction and revenue-splitting algorithms
—Deployed to cloud production and coordinated adoption across the driver fleet

E-Commerce Platform03

Hobby Collectibles Storefront

Full-stack e-commerce storefront with instant multi-facet filtering

~70%

Reduction in repetitive price & stock inquiry messages through multi-facet filtering; customers self-serve quickly.

Friction:

The store stocked hundreds of model kits across diverse lines. Slow page loads and poor navigation made it frustrating for buyers to find items.

Solution:

Developed a fast Next.js & Tailwind CSS storefront using AI coding tools: restructured product taxonomy, built instant multi-facet filtering (series/brand/price), and streamlined checkout.

Interactive E-Commerce04

Luxury Perfume Boutique

Interactive e-commerce web app with scent attribute visualization

Direct

Visualized fragrance notes and occasion recommendations drove significantly higher direct consultation inquiries.

Friction:

Shopping for fragrance online is difficult when descriptions are vague and text-heavy, causing high visitor drop-off before checkout.

Solution:

Designed and built an interactive storefront that visually maps fragrance notes (top, heart, base), longevity, and occasion tags, paired with a 1-tap consultation trigger.
