VS CodeProof of Work
Real projects with real challenges, engineered solutions, and measurable outcomes.
Azurea Hotel Management System
Problem
Manual booking tracking and room administration created high administrative overhead and double-booking risks.
Solution
Developed a unified dashboard with transaction validation, room CRUD management, and a guest rating system.
Simulated API Latency: <150ms | 99.8% booking verification accuracy
Savoury
Problem
Cooking enthusiasts lacked an integrated tool to discover recipes and dynamically generate coordinate shopping lists.
Solution
Created a recipe-sharing portal built with Next.js App Router and PostgreSQL listing matching.
PostgreSQL Indexed Search: <50ms under load
Commitly
Problem
Developers struggle to build coding habits due to isolated GitHub streak tracking and lack of active notifications.
Solution
A React Native mobile app integrating manual entry sync, stats dashboards, and automated GitHub API calendars.
Local DB Sync: <50ms | offline persistence using Zustand & Firebase
PrintBit
Problem
Lack of self-service document printing stations forced manual operations in academic universities, leading to inefficiencies and long wait times.
Solution
Engineered a coin-operated document printing kiosk machine with multi-format support and real-time monitoring.
Coin Verification: <1s | Node.js serial controller verification
SariSari
Problem
Small sari-sari store owners lacked accessible tools for inventory and sales management, leading to manual tracking and financial inefficiencies.
Solution
Developed an offline-first React Native app with SQLite for inventory, sales, and loan tracking tailored to small sari-sari store needs.
SQLite local queries: <100ms | Offline data sync on reconnect
