Summary

I’m a Full Stack Software Engineer with over three years of hands-on experience building reliable, scalable web applications across energy, industrial, and technology domains. I enjoy working with React, JavaScript, TypeScript, and Node.js, and I also have experience with Java, Python, AWS, and SQL databases. I’m comfortable working in Agile teams, setting up CI/CD pipelines, and writing automated tests with Jest and Cypress to keep code quality high. I recently completed a Master of Information Technology at RMIT University, and I’m especially motivated by turning complex requirements into simple, user-focused solutions through close collaboration and practical problem-solving.
