I build software systems people actually work in.
Software Developer focused on web applications, reusable UI, and business systems — from database design and REST APIs to the interfaces teams use every day.

About
I like building software from the inside out.
I'm a Software Developer focused on building web applications and business systems. At ACS Engineering & Services, I work on Nexus, a multi-tenant facility and maintenance management platform, across the stack from PostgreSQL data models and REST APIs to React interfaces and reusable UI components.
A big part of my work is turning repeated patterns into reusable systems — data tables, calendars, dashboards, charts, forms, permissions, reporting, and application modules. I enjoy figuring out how these pieces should work together rather than implementing them one screen at a time.
Before software development, I worked in enterprise IT support, where I learned how software behaves in the real world — when systems break, users need help, and reliability matters.
Work
Selected projects — what they do and what they run on.
Nexus — ICMMS
Multi-tenant, subscription-based facility and maintenance management system running live across sites including DBKL Jabatan Saloma and DBKL Jejantas Tun Teja. Built operational modules, REST APIs, and database schemas covering task management, claims, inventory, attendance, tickets, notices, event management, team scheduling, dashboards, and reporting — plus a Presentation Mode that turns operational data into presentation-ready slides. The subscription model lets each organisation switch on only the services their operations need.
Building Link System
Resident and property management app for web and mobile: announcements, facility bookings, payments, parking, emergency requests, live chat, events, and resident services. Bachelor's final year project.
Healthy Diet Application
Mobile diet-planning app with meal planning, nutritional guidance, and healthy lifestyle tracking. Diploma final project.
Experience
Where I have worked and what I shipped while I was there.
Develop and maintain Nexus, a multi-tenant facility and maintenance management system built on Next.js, React, TypeScript, TanStack, Prisma ORM, and PostgreSQL. Build reusable components for calendars, data tables, dashboards, charts, and forms alongside application modules, REST APIs, and database schemas, and implement user management, CSV import, role-based access control, reporting, Supabase Storage file management, and a built-in Presentation Mode. Collaborate on feature planning, code reviews, testing, and troubleshooting across frontend, API, and database layers.
Onsite and remote IT support for enterprise clients including TNB, Sunway Group, and McDonald's. Installed, configured, and troubleshot servers, workstations, printers, software, and network devices while minimising downtime, and handled server setup, user account management, system access, and basic security controls.
