Systems I've Shipped

Real products built and maintained at Cubixi WorldWide — for businesses, government agencies, and students across Malaysia.

I. CUBIXI 2022 — Present

Cubixi WorldWide — In-house SaaS

Cubixi's in-house SaaS for client and vendor project management, spanning CuCommand and CuPowerhouse. I helped shape its technical roadmap and architecture alongside the Lead Developer and business team, and built core HR modules for Leave Management, Claims, and Attendance. I integrated OpenAI to upload and extract files into Key Deliverable Details that export straight to the CuCommand Gantt chart, added an OpenAI-powered chat module, and built a 360 Organization feature giving visibility across peers, managers, and subordinates.

JKKP — Dept. of Occupational Safety & Health

A government system where I serve as a key-player developer in Java Spring and PostgreSQL. I built secure API integrations with MyKKP for bidirectional data exchange and single sign-on authentication, mentor junior developers and interns, and run code reviews that enforce standards. My focus is system reliability, scalability, and performance compliance.

A multi-merchant e-commerce platform launched within a three-week deadline: a scalable online bookstore letting major retailers sell directly to students. I built a voucher redemption workflow for secure, controlled fund utilisation, integrated the Google Maps API for student location verification and delivery validation, and wrote IC number validation logic to prevent fraud and duplicate voucher claims.

The developer

About Me

I am a senior software developer based in Malaysia with over four years of experience identifying, designing, researching, implementing, and managing software systems — internal programmes that make businesses more efficient, and full systems built for daily life, business, and management.

Most of my work lives inside Cubixi WorldWide, where I help shape technical roadmaps and architecture. I've built core HR modules, integrated AI features powered by OpenAI, delivered secure government API integrations, and launched a multi-merchant e-commerce platform under a three-week deadline — working in Java Spring Boot, Laravel, and PostgreSQL with an eye on reliability and code quality.

I'm drawn to the harder problems: debugging, reverse engineering, and untangling the kind of complexity that resists a quick answer. I'm now looking for my next role where I can keep building things that matter.

Mentorship

I mentor junior developers and interns through code reviews and technical coaching, enforcing coding standards and best practices.

Full-Stack Breadth

I move fluently between front-end and back-end, and across two major ecosystems — Java / Spring Boot and Laravel / PHP.

Architecture & Quality

I work with the Lead Developer and business team on system architecture, optimising for performance, security, and long-term maintainability.
