Dear Hiring Manager, I am writing to apply for the Software Engineer position at Tyro. With a Master of Information Technology from Monash University and experience building production software at a payments-focused SaaS startup, I am drawn to Tyro's mission of making payments seamless for Australian merchants. As a Software Engineer at Wabi, I have worked across the full delivery lifecycle of a cross-platform POS system with integrated payment processing, covering authentication, real-time transaction flows, WebSocket synchronisation, and REST API integrations. I have also worked with AWS services including S3, Lambda, and DynamoDB, and have set up CI/CD pipelines using GitHub Actions. My database experience spans MySQL, MongoDB, and PostgreSQL, including designing schemas to handle both structured billing data and real-time data streams. I am comfortable writing and optimising SQL queries, and I understand the importance of clean, maintainable code across the full stack. I have been using AI-assisted development tools including GitHub Copilot and Claude Code as part of my daily workflow, which aligns to experimenting with new technologies. I enjoy working closely with designers, product managers, and other engineers to solve problems and ship things that actually work. That collaborative approach is something I value deeply.
