What I'm looking for

I'm looking to build production full-stack, mobile, and backend features, particularly for IoT-driven products, while contributing through agile delivery, code reviews, and continuous technical growth.

At SenzMate, I build production backend services and REST APIs with Java and Spring Boot, alongside React and React Native applications for IoT and energy-management products.

I was promoted from Intern Software Engineer to Associate Software Engineer within a year and recognised as Best Performer of the Year. My work includes device-to-cloud workflows, real-time data ingestion, secure JWT authentication, role-based authorisation, and reusable cross-platform interfaces.

I also built Lumix, a React Native electricity-management system that connects ESP32 devices, Node.js, Firebase, real-time dashboards, and energy-saving insights.

Across personal and academic projects, I've delivered finance, e-commerce, leave-management, and inventory systems using React, TypeScript, .NET, Java, Spring Boot, Node.js, PostgreSQL, MySQL, and MongoDB.
