Tzu-Lun (Alan) Wong

// Atlassian

Worked on Jira Service Management Assets across CMDB imports, integrations, asset collaboration, and enterprise customer support workflows.

• Co-led a legacy CMDB import refactor to support customer-assigned ExternalID values and deduplicate Azure and customer-managed data sources.
• Scaled and supported imports of 5M+ assets, diagnosing enterprise failures through log tracing and support analysis
• Led end-to-end delivery of object-level comments for assets, incidents, and ownership records.
• Diagnosed stale JVM build-chain concurrency and memory leaks, reducing integration test failures from about 20% to under 5%.
• Raised legacy codebase test coverage above 80% and kept newly added code above that threshold through focused unit and integration testing.
• Investigated and resolved import edge cases involving large strings, repeated names, international text, and partial data recovery for enterprise customers.

// Tyro Payments

Built POS integrations, payment-terminal workflows, merchant-facing tools, monitoring, and scheme-compliance product changes in a full XP environment.

• Implemented tipping prompts on Tyro payment terminals for hospitality merchants, shipping a durable customer-facing feature still visible in restaurants years after launch.
• Solo-developed a terminal-based customer satisfaction survey flow that helped retain a major merchant.
• Delivered POS integration upgrades, integration monitoring, Alipay integration, scheme compliance maintenance, terminal and cardholder rating UX, and internal pricing/quoting tools.

// Integrated Research

Contributed to Prognosis enterprise monitoring across IP telephony, payments, support tooling, QA, and customer-driven product development.

• Developed product features and showcased new capabilities directly to enterprise customers.
• Voluntarily enhanced build tooling to cut product build times by around 50%.
• Mentored a graduate engineer and briefly acted as product owner during Graduate Innovation Week.
