Cover image for A comprehensive workshop and fleet
A comprehensive workshop and fleet management system for a 21-bus intercity transit operator, built to scale to hundreds of vehicles. Pre-departure safety inspections run on mobile — all checklist items default to pass, the checker only flags failures. Any failed item automatically creates a workshop job card and flags that departure as NOT CLEARED — defects cannot be verbally communicated and forgotten. The inspection checklist is fully admin-configurable without any code changes. Workshop job cards track parts used, labour, mechanic assigned, and total cost with attribution by bus ownership type. Built on Next.js 14, Neon Postgres, Drizzle ORM, NextAuth v5, Vercel — $0/month running cost. Currently in active development.

Cover image for A chain-of-custody system for a
A chain-of-custody system for a cargo storehouse eliminating parcel accountability gaps and TO_PAY cash leakage. Every parcel is tracked from entry to release with full staff attribution. Releasing a TO_PAY parcel requires confirming cash collection before the system allows it. At shift end, the handover screen snapshots total parcels and cash collected per staff member — locked and timestamped. A void bilty feature handles real-world edge cases with full audit trail. Daily cash reports grouped by staff member replaced manual reconciliation entirely. Built on Next.js 14, Neon Postgres, Drizzle ORM, NextAuth v5, Vercel — $0/month running cost.

Cover image for A kiosk-based Progressive Web App
A kiosk-based Progressive Web App for a bus terminal managing 100+ daily-wage workers. Workers find themselves on a photo grid, tap their tile, enter a PIN, and the camera auto-captures their photo on clock-in. Built with an offline buffer — punches are stored locally when internet drops and auto-sync when connectivity returns. No punches are ever lost. Supervisors have a real-time dashboard showing present, absent, late, and missing-checkout status. Monthly reports export to CSV. Built on Next.js 14, Neon Postgres, Cloudflare R2, Vercel — $0/month running cost.
