What I'm looking for

I’m looking for a role where I can own end-to-end feature delivery, context-switch across stacks when needed, and keep building decoupled frontend/backend systems that stay low-maintenance over time.

I built and maintained full-stack features for 10+ client applications at Industry Blitzm Systems Pty Ltd, working across ReactJS, .NET, Django, Node.js, and MySQL/PostgreSQL. I also acted as the solo developer and primary technical liaison for some clients—gathering requirements, managing scope, and delivering end-to-end features.

Before that, I shipped backend API endpoints and SQL-driven functionality at GoodHuman using Express.js, Knex.js, and ReactJS, including documentation to help frontend teams integrate faster. Earlier, my internship at Techvus Sdn Bhd focused on relational database design, responsive UI components, and interactive data visualizations powered by API-sourced data.
