from MYR 1,000 onwards About me
I like to build web app solutions.
Of all my experience building apps — from web apps to native mobile — I prefer to focus on the logic and keep the UI simple, so people can use it without friction.
- Where it started
A system for my community library
The first thing I ever coded was a lending system for the library in my own community.
- Software house
F&B and food-delivery marketplaces
Got hired into a software house to build ordering, kitchen and delivery-marketplace systems.
- Agriculture
Resource planning for poultry farms
Worked out ideal feed-transportation routes and schedules across farms.
- Before code
Direct-sales business executive
Sold direct-sales software before writing it — so I understand the business side of what I build.
Time spent during development
