What I'm looking for

I'm looking for a full-time backend or data engineering role where I can contribute to building scalable, reliable systems and continue growing my technical expertise and I need a full-time job to complete the PR application. I value collaborative teams, meaningful projects, and opportunities to work with modern technologies in a fast-paced environment.

I’m a Computer Science graduate from UNSW with a minor in Information Systems and strong backend development experience. I’ve worked on multiple large-scale software projects, including a short-term rental platform deployed on AWS and a collectibles trading system. My technical strengths include Python, SQL, C, Spark, and PostgreSQL, and I’m well-versed in software architecture, database optimization, and distributed systems.

I’ve also completed internships in cybersecurity and quantitative finance, where I built automation scripts, optimized SQL queries, and developed predictive models with scikit-learn. These experiences sharpened my problem-solving skills and deepened my interest in AI, cloud computing, and high-performance systems.

Outside of work, I run a personal blog, enjoy exploring algorithmic challenges on LeetCode, and occasionally create bilingual subtitles for educational content. I’m currently looking for a full-time backend or data engineering role where I can contribute to impactful projects and continue growing alongside talented teams.
