Full-stack developer — from design to production.

I'm Khairul Imran. 6 years building for the web — the last 2 as a full-stack developer in fintech, shipping a payment gateway with ten official SDKs, a transactional-mail platform, and a WhatsApp business-messaging product.

Day to day that means Laravel, Node and Vue on top — and the Linux servers, Docker containers and mail daemons underneath.

Ex-web designer. I still sweat how things look — now I also own how they run.

Experience

2024 —

Full-stack developer · Web Impian

Payments (Bayarcash), transactional mail (Mailniaga), WhatsApp CPaaS and internal observability. Laravel, Filament, Node, and the servers underneath — I build it and I run it.

2020 — 2024

Web designer

WordPress and WooCommerce builds for Malaysian businesses — design, theming, and maintenance. Where I learned that shipped beats perfect, and that someone has to keep the thing alive after launch.

2016 — 2020

BSc Computer Science (Web Technology) · UTHM
