What I built

  • Overview dashboard with occupancy, expected vs. collected rent, outstanding rent, and monthly expenses.
  • Shops & rooms and tenants modules to manage every unit and who occupies it.
  • Rent & payments with paid, partially paid, unpaid, and overdue statuses.
  • Electricity tracking per connection, including bills received, bills pending, and total due.
  • Maintenance, activity logs, and plaza setup so owners can run the whole building from one place.

International Government Programme — Field Operations App

A secure mobile app for field teams to register cases, capture data offline, and report back to programme administrators.

Platform · Flutter · iOS & Android

  • Flutter
  • Offline-first
  • Data security
  • Multi-language

Context

One of two international government projects I contributed to. Field staff needed a dependable tool that worked in low-connectivity areas and met strict data-handling expectations.

My contribution

  • Built offline-first data capture with local storage and conflict-safe sync.
  • Implemented structured forms with validation, photo capture, and GPS tagging.
  • Delivered multi-language support so the app could be used by local teams.
  • Worked within a larger team to meet the programme's review, security, and release processes.

Outcome

A stable app used by field teams in real conditions, with clean, consistent data reaching administrators.

HR & Payroll Portal

Employee records, leave requests, attendance, and monthly payroll with payslips — built as a custom web application.

Platform · Custom web app

  • Custom code
  • REST API
  • PDF payslips
  • Approvals

Highlights

  • Employee directory with documents, contracts, and history.
  • Leave & approvals workflow with manager sign-off and balances calculated automatically.
  • Payroll runs with allowances, deductions, and downloadable PDF payslips.
  • Audit trail so every change to sensitive data is traceable.

Hand-written code gave full control over calculations and permissions — the parts of HR software that can't be approximate.

08Management system2025

Inventory & Point-of-Sale Management System

A multi-branch stock, sales, and purchasing system with a mobile POS for the shop floor and a web dashboard for owners.

Platform · Flutter · Web dashboard

  • Flutter
  • Firebase
  • Role-based access
  • Reporting

The problem

Stock lived in spreadsheets, sales lived in a cash register, and nobody knew what was actually on the shelves until month-end.

What I built

  • Mobile POS with barcode scanning, offline sales, and automatic sync when the connection returns.
  • Owner dashboard with live sales, low-stock alerts, and branch-by-branch comparison.
  • Purchasing & suppliers module: purchase orders, goods received, and supplier balances.
  • Roles for owners, managers, and cashiers, so each person only sees what they need.

Outcome

One source of truth for stock and sales across every branch, with daily reports that used to take days now available instantly.

Platform · Bubble · FlutterFlow

  • Bubble
  • FlutterFlow
  • Payments
  • Notifications

Scope

Schools juggle students, staff, fees, and parents. This system brings all of it into one place.

  • Admin panel (Bubble): admissions, class & section setup, timetables, fee schedules, and exam results.
  • Teacher app (FlutterFlow): one-tap attendance and marks entry.
  • Parent app: fee reminders, results, notices, and attendance alerts via push notifications.

Why this stack

Bubble and FlutterFlow let the school launch quickly and iterate with real feedback, while custom code handled reports and integrations.
